Wi-Fi performance and known issues on SBC


Recommended Posts

As already done with other topics this will be the start of a new thread collecting more information over time.

 

Since we had a lot of annoying discussions recently regarding Wi-Fi on Orange Pi Zero and in general I thought let's give it a try a few days ago. I did some preparations in the meantime (monitoring 24/7 Wi-Fi throughput in 2.4 GHz band for example) and then started to test in a not too crowded environment here.

 

As a start some quick Wi-Fi tests with a random 'quality' USB Wi-Fi dongle and 3 different Wi-Fi chipsets that can be found an a few boards Armbian supports:

 

  • RTL8192CU (used on a lot of cheap USB dongles and even on Lamobo R1)
  • Ampak AP6212 (based on Broadcom's BCM43438 module also used on RPi 3 and Zero W, nearly all Wi-Fi equipped NanoPi and Banana Pi)
  • RealTek RTL8723BS (used on Pine64+ and on CHIP for example)
  • RealTek 8189FTV (used on the more recent Wi-Fi equipped Orange Pi)

 

The usual Wi-Fi performance 'benchmark' results available here and there most of the time ignore a lot of important bits, eg.

 

  • Environment (Wi-Fi means shared media so in crowded areas with a lot of other Wi-Fis around you fight for free slots on the media, even USB3 peripherals or microwave ovens happily interfere with your Wi-Fi performance)
  • Environment (yeah, again: This time aerial/antenna used, position of antenna in relation to AP, distance, free sight or not, walls/stuff that filter or reflect signals)
  • Settings (Wi-Fi powermanagement enabled or not? Which cpufreq governor used? Performance results can vary based on at which clockspeed CPU cores run)

 

So for the test I chose to let all boards run with performance governor and Wi-Fi powermanagement disabled. All are equipped with the same el cheapo Xunlong aerial (sent with all Orange Pi that are Wi-Fi capable). Position of antenna is always the same, distance from AP (Fritzbox 7390) to board approx 50 cm, AP in cabinet (20mm MDF). Almost same environmental conditions (due to some testing delays I could not guarantee that Wi-Fi channel utilization was always the same but since I let a constant iperf3 monitoring run for the last couple of days I chose time slots where maximum throughput seemed to be possible).

 

Also no Ethernet connected (since it's easy to f*ck up performance tests in this scenario when wired and wireless interfaces of both device and router/AP are somehow all connected since some kernels then send packets over the wrong interface) and Wi-Fi connection established the usual way (nmtui --> 'Activate connection' --> done) with /etc/network/interfaces being empty (to let network-manager control all devices for smooth networking).

 

Now the results:

 

NanoPi Air with el cheapo Xunlong aerial, AP6212 module, Kernel 3.4.113, no BT configured: 39 Mbits/sec and 188 retransmits on average. Full log: http://sprunge.us/aPXb

How to interpret the results?

 

  • The test setup is stupid for any real world consideration (if distance between device and AP is just 50 cm then use a cable instead! ;) ) But this set of tests was about identifying the maximum you can get under perfect or at least pretty good conditions (no interference, rather good signal/noise ratio and so on)
  • All 3 onboard Wi-Fi chips perform identical. This is due to single antenna 2.4 GHz Wi-Fi: 65Mbps bit rate resulting in ~40 Mbit/sec TCP/IP throughput with ideal/good/identical environmental conditions
  • The only reason the TP-Link Wi-Fi dongle could outperform the onboard Wi-Fi chips is called MIMO. This is available with 802.11n and makes use of more than one antenna (2 in this dongle's case). Now we're talking about 130 Mbps bit rate resulting in almost 80 Mbit/sec TCP/IP throughput

 

Next steps:

 

Let's have a look how worse environmental conditions affect performance. This means increasing distance between AP and device, put a few walls in between, use a more crappy antenna. To save some time I will continue the testing solely with the TP-Link Wi-Fi dongle (connected to the ODROID but here the board doesn't matter at all, it's just about the driver variant/version used) and Orange Pi Lite since this is the cheapest 'general purpose Wi-Fi' enabled board Armbian supports and the same chip is also used on OPi PC Plus and OPi Plus 2E (which are both also priced very competitively for their feature set).

 

But I will add also results from Raspberry Zero W if this board ever arrives (if not I'll take RPi 3 instead, both use same BCM43438 chip that is also contained in Ampak's AP6212 which is the solution present on most Wi-Fi enabled Armbian boards)

Small update: Tried two more locations within the same building with OPi Lite and the other board with RTL8192CU MIMO dongle:

 

Location 1: 4 meters away, 2 walls in between, wall angle approx. 30°

 

Orange Pi Lite: 33 Mbits/sec on average

EDIT: Silly me forgot to disable Wi-Fi powermanagement. Will redo all tests now and update results in a few minutes.

 

I wanted to test with RPi Zero W but since the board is still not here I'm testing with RPi 3 now (uses same Wi-Fi/BT chip and also a small onboard antenna). I upgraded the kernel to latest available version 4.9.13-v7+ and applied all other updates. Some log output here.

 

All tests were done as above, I simply put the Raspberry in the 3 different rooms at exactly the same position and fired up the same set of tests again:

 

RPi 3 being 50cm away from AP: 37.4Mbits/s on average and over 3000 retransmits when testing in RX direction.

Now repeating the test with RPi 3 at all 3 locations again. I tested first with powermanagement disabled just to realize that not that much changed. So I decided to write a small script to automatically test through 60 second iperf3 iterations in each direction (TX/RX) with enabled and later disabled powermanagement. This will be repeated 4 times each and end result will simply be used as an average value:

powermanagement on:  39.22 Mbits/sec 
powermanagement off: 39.26 Mbits/sec

4 hours ago (see above): 37.4 Mbits/sec

 

Location 1:
powermanagement on:  20.17 Mbits/sec
powermanagement off: 22.72 Mbits/sec

4 hours ago (see above): 10.4 Mbits/sec

 

Location 2:
powermanagement on:  12.14 Mbits/sec
powermanagement off: 11.89 Mbits/sec

4 hours ago (see above): 6 Mbits/sec

 

So for whatever reasons results do not vary that much depending on powermanagement being enabled or disabled. But the numbers with enabled powermanagement from a few hours ago were a lot lower if tested in remote rooms. I thought what might have been different and two things came to my mind:

  • different board placement affecting efficiency of RPi 3's onboard antenna
  • a DECT handset lying just in between RPi and AP in location 2

So I put the handset back and re-tested:

 

Location 2 with DECT handset next to RPi 3:
powermanagement on:  12.02 Mbits/sec
powermanagement off: 11.74 Mbits/sec

 

Obviously other influences are responsible for the drastic change in numbers or powermanagement settings work somehow differently.

 

 

 

Bash script to test this (tested in Raspbian but should work with any recent Armbian installation too):

#!/bin/bash

Test() {
	iwconfig wlan0 power $1
	sleep 5
	iperf3 -c 192.168.83.146 -t 60 | egrep "sender|receiver" >>${tmpdir}/$1.txt
	sleep 5
	iperf3 -R -c 192.168.83.146 -t 60 | egrep "sender|receiver" >>${tmpdir}/$1.txt
	iwconfig wlan0 
} # Test

tmpdir=$(mktemp -d /tmp/check-wifi.XXXXXX)
for i in on off on off on off on off ; do
	Test $i
done
unset LANG
on_average=$(awk 'BEGIN {FS = " "} ; {sum+=$7} END {printf ("%0.2f",sum/16)}' ${tmpdir}/on.txt)
off_average=$(awk 'BEGIN {FS = " "} ; {sum+=$7} END {printf ("%0.2f",sum/16)}' ${tmpdir}/off.txt)
echo -e "powermanagement on:  ${on_average} Mbits/sec\npowermanagement off: ${off_average} Mbits/sec\n"
echo -e "powermanagement on:  ${on_average} Mbits/sec"
cat ${tmpdir}/on.txt
echo "powermanagement off: ${off_average} Mbits/sec"
cat ${tmpdir}/off.txt
rm -rf ${tmpdir}

Just to check the above thoughts I tested with the script on OPi Lite again. Only in 'Location 2' where results from yesterday were 23.5 Mbits/sec on average. Now the script reports

powermanagement on:  24.59 Mbits/sec
powermanagement off: 27.04 Mbits/sec

 

In fact powermanagement can not be enabled with legacy 8189fs driver (see messages below) so the difference is just result variation. And the same can be seen also from script output below since sometimes bandwidth drops down to even just 8.x Mbits/sec. So as expected the environment matters a lot, a single neighbor with a Wi-Fi active on same or nearby channels can ruin bandwidth/performance anytime:

Time to stop for today. I got notification from buyzero.de that my Zero W is ready to be shipped so next try is then with new Raspberry Zero's onboard Wi-Fi (according to RPi folks antenna should be better than the one on RPi 3 but to be honest: I don't expect good results in locations 1 and 2 as well since no U.FL connector ready for a real antenna is on the PCB)

Next round of tests in 'location 3' (still 5m away from AP with 2 walls in between, 1 m next to 'location 2' but with less troublesome stuff between devices and AP). I use the script from above to see whether enabling/disabling Wi-Fi powermanagement does change anything (or is possible at all). Obviously enabling/disabling on RPi 3 has no effect (brcmfmac driver), with RTL8189FTV and RTL8192CU is was not possible (same error message from iwconfig: 'Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Operation not permitted.'), only with AP6212 (using legacy kernel dhd module) there were huge differences in performance.

 

I chose two rounds of tests at different times of the day. The first ran was shortly after midnight and the 2nd run started at 10:00 in the morning. This time I tried to find optimal antenna position but obviously that did not work that great with the TL-WN823N dongle (I have to admit that I slightly changed antenna positions between 1st and 2nd run, also not the best idea).

 

Software settings remained the same to before (so you can check dmesg output and so on above) and boards were tested one at a time (test execution lasts ~20 minutes which is also bad since environmental conditions between different test runs can change in between since for example the neighbour next to me transfers 15 min large amounts of data in his Wi-Fi interfering with mine and ruining performance in my network)

 

Results as follows, on the left nightly results as averaged iperf3 throughput numbers followed by those from now. 

 

NanoPi Air, AP6212 module, external small vertical aerial:

powermanagement on:  5.53 / 5.16 Mbits/sec
powermanagement off: 30.14 / 14.66 Mbits/sec

 

Orange Pi Lite, RTL8189FTV module, external small vertical aerial:

powermanagement on:  30.47 / 32.41 Mbits/sec
powermanagement off: 30.57 / 32.56 Mbits/sec

 

ODROID-C2 with TP-Link MIMO TL-WN823N dongle, RTL8192CU module, upright position:

powermanagement on:  34.90 / 48.51 Mbits/sec
powermanagement off: 35.34 / 49.27 Mbits/sec

 

RPi 3, BCM43438 module, onboard antenna oriented obviously properly:

powermanagement on:  35.42 / 25.59 Mbits/sec
powermanagement off: 34.56 / 25.13 Mbits/sec

How to interpret the results?

  • Powermanagement on/off matters at least with AP6212. With the other implementations there was no difference and numbers for on/off are just result variation. Further investigation needed whether it's just not possible adjusting PM settings with iwconfig or if it's not possible at all
  • Environmental conditions matter at lot. Between the two test runs nothing regarding software/settings has changed, it was just different time of the day and slightly moving around antennas/boards. IMO it's already pretty obvious that this sort of 'performance' testing in real-world environments is too stupid to be continued since numbers depend highly on stuff you can't control.

When RPi Zero W arrives I will add it to the test setup and move the whole setup to 'location 4' (will have to ask my neighbour to host the cardboard box with the 5 SBC inside). And then I might rewrite the testing script so that I can test through each board every 60 seconds to minimize external temporary influences.

 

Also interesting whether performance of TL-WN823N dongle improves when operated horizontally and not upright (Edit: nope). Same with Raspberries and their onboard antenna but here it seems upright position is better (at least when comparing the average 30 Mbits/sec from this test with the results from yesterday with RPi 3 just lying randomly around: 6 and 12 Mbits/sec)

Finally testing 'location 4': 11m away from my AP in neighbour's flat with 3 walls and some chimneys in between.

 

NanoPi Air, AP6212 module, external small vertical aerial:

powermanagement on:  2.38 Mbits/sec
powermanagement off: 3.46 Mbits/sec

 

Orange Pi Lite, RTL8189FTV module, external small vertical aerial:

powermanagement on:  4.90 Mbits/sec
powermanagement off: 4.49 Mbits/sec

 

ODROID-C2 with TP-Link MIMO TL-WN823N dongle, RTL8192CU module, horizontal position and antenna oriented towards AP:

powermanagement on:  18.43 Mbits/sec
powermanagement off: 18.99 Mbits/sec

 

RPi 3, BCM43438 module, onboard antenna oriented obviously properly:

powermanagement on:  3.88 Mbits/sec
powermanagement off: 4.02 Mbits/sec

Some notes:

 

1) Still 'powermanagement on/off' has no meaning except for NanoPi Air since for the other boards it's just an example for result variation (to remember to never trust any 'benchmark' numbers you find on the net)


2) RPi 3 lost connection to AP in between (automagically re-established by network-manager a few minutes ago). That's the 'valley' left to the middle of this RX/TX graph (green are signals emitted from Fritzbox AP, blue are signals received and 'foreign' signals):
Bildschirmfoto%202017-03-09%20um%2012.08

 

3) Interestingly the difference between enabled/disabled powermanagement doesn't matter that much any more with AP6212 in this scenario (I guess I'll have to compare ping roundtrip times to get the full picture?)


4) Cheap OPi Lite with RTL8189FTV is the best single antenna performer here. But results differed a lot, there were some periods of time where 60 second average iperf3 numbers exceeded 13 Mbits/sec:

5) The winner is the TL-WN823N USB dongle since... 2x2 MIMO is useable here. Two antennas instead of one greatly improve performance in this scenario. Please note that this requires an 802.11n capable AP that also features at least the same count of antennas!

 

 

Edit: As outlined in 3) above I tried to test ping roundtrip times with AP6212 and Wi-Fi powermanagement enabled/disabled. First try from location 4 (neighbour) with active PM and 120 seconds ping:

rtt min/avg/max/mdev = 16.347/102.990/321.107/67.430 ms

Then NanoPi Air disappeared from the net and never reconnected back. So I put the boards back to my home and tried it in 'location 1' with NanoPi Air again. First numbers are with PM on, second off:

rtt min/avg/max/mdev = 3.566/77.707/342.230/44.283 ms
rtt min/avg/max/mdev = 1.902/3.780/32.376/4.540 ms

So obviously for doing anything interactive over Wi-Fi (eg SSH) PM disabled is a great idea (average ping times 4 ms vs. 78 ms!). I tested then with RPi 3 (same Wi-Fi module but here mainline kernel driver and not dhd) with PM on/off. Here only minimum roundtrip times increased with enabled PM but also 5% packet loss occured:

rtt min/avg/max/mdev = 4.682/55.697/409.561/97.636 ms
rtt min/avg/max/mdev = 1.653/59.969/493.176/65.494 ms

And another small update regarding the test setup. AP is a Fritzbox 7390 with latest firmware in a not so ideal location (mounted vertically in a wooden cabinet approx.  50 cm above the floor and 30cm next to another Fritzbox used as DSL modem and DECT basestation). The AP is configured to allow '100%' TX power (but based on the results above I would assume it's trying to play 'green' from time to time). The host all tests are running against is a virtualized Ubuntu running 'iperf3 -s' and the ESXi host is connected through GBit Ethernet to one of the Fritzbox' GBit LAN ports.

 

The AP is configured to allow 802.11n/g (no 802.11b!) in 2.4GHz band and to choose best channel possible (always 13 since least utilized compared to the other ones):

Bildschirmfoto%202017-03-09%20um%2013.06

 

So while this is a pretty 'normal'/real-world setup it's also not suited to do reasonable testing. I might need a lab environment where external influences can be minimized or at least controlled (not possible at all here) and a less intelligent AP too. But hey, why bother? Single antenna 2.4GHz Wi-Fi in crowded areas was already known as almost broken before and the few tests just verified well known facts.

 

From an Armbian (software) point of view we know that drivers/settings for onboard Wi-Fis that can be found on the boards we support seem to fit. Also maximum performance possible is defined by physical limitations (65Mbps bit rate on all boards with single antenna 2.4GHz Wi-Fi define ~40 Mbits/sec with TCP/IP max, theoretically 130Mbps on Lamobo R1 should show better results but reality looks different there). Real-world performance does not depend on driver/settings but obviously on physical/environmental conditions (type/orientation/position of antenna, utilization of Wi-Fi channels due to interference caused by other Wi-Fi devices or  stuff like DECT, microwave ovens, USB3 peripherals near the device/AP)

 

So what to look into next (real question since I still feel being a Wi-Fi noob):

  • powermanagement settings?
  • TX power settings (regulatory domain stuff, real power available)?
  • recommendations for capable USB dongles that work out of the box (mine does with Armbian)?
  • what did I miss?

In the meantime my Zero W arrived and it took me only 1 hour to set up Raspbian headlessly on the device: 

 

 

Quick Wi-Fi test made in 'location 1' using the well known script from above (still not showing differences regarding powermanagement since this also has no effect on the Zero W -- it's still just result variation):

 

RPi 3 (kernel 4.9.13-v7+):

powermanagement on:  23.36 Mbits/sec
powermanagement off: 22.54 Mbits/sec

 

RPi Zero W (kernel 4.4.50+):

powermanagement on:  28.54 Mbits/sec
powermanagement off: 27.68 Mbits/sec

 

RPi Zero W (after kernel upgrade to 4.9.13-v7+):

powermanagement on:  24.58 Mbits/sec
powermanagement off: 25.49 Mbits/sec

 

So throughput is the same or at least not lower (tests done all at different hours so not comparable since uncontrolled environment) and that's also a good reason to not further waste time with RPi tests. To my surprise onboard aerials of both WiFi equipped RPi work quite well but can't overcome 2.4GHz single antenna limitations of course. For some numbers with more antennas, 5GHz too and also 802.11ac see here for example: https://netbeez.net/2016/06/01/iperf-wifi-comparison-on-raspberry-pi-raspberry-pi-3-vs-asus-vs-hawking-vs-linksys-vs-tp-link/

I did some tests with the NEO Air in the recent days, borrowing the antenna from an OPi Zero. Since I experienced some serious lag while typing over ssh, one of the first moves was putting the thing line of sight to the router. This helped a little, but not much.

 

Now I have been playing with iperf and several different setups. I have a second antenna that came with an OPi One. It's the same model that comes with the Zero, but seemed to double the performance. I saw a jump from 10 MBit/s to 20 MBit/s.

 

Then I tried putting an old harddisk behind the antenna as as some sort of makeshift reflector (varying the distance as well). In one case it seemed to boost the signal, iperf went from something around 20 MBit/s to 30 MBit/s. Also, placing the HDD between the antenna and the router significantly decreased the signal.

 

Orienting the antenna differently also had an effect. At one point performance even went down to 1 MBit/s. That's when I realised the u.FL-connector was no longer properly connected.

 

So here is my takeaway: While they might do the job, OPi's stock antennas may vary in quality. I guess there is no quality check at the end of the assembly line. Also, it is very easy to screw up things. The consumer mindset -- plug it in in and expect it to work flawlessly -- is certainly not the right approach here.

 

The good news is: To a certain degree you can improve things by optimizing the antenna. I see a bright future for tinfoil reflectors and cantennas. . .

:P

 

Boring details: There are more than 50 Wifis in the 2,4 GHz band visible at my place, so none of this qualifies as a science experiment. When using iperf, distance to the router was apr. 4 metres through air and a brick wall. Above ratios came from iperf's default mode. Reverse operation (iperf3 -R) makes roughly a +10 MBit/s difference.

Maybe that was just 'casual benchmarking': you benchmark A, but actually measure B, and conclude you've measured C?

 

I exchanged the cheap Xunlong antenna on OPi Lite now with a much larger one and repeated the 2 tests from above: 50 cm next to the AP througput increased from 41.5 Mbits/sec to 44.8 Mbits/sec (so antenna seems to be 'better') and then I repeated test with 'location 4' at my neighbour's place, 11m away. With Xunlong antenna I got this a few hours ago:

powermanagement on:  4.90 Mbits/sec
powermanagement off: 4.49 Mbits/sec

When I tested now again with the larger antenna, numbers were worse. So I decided to repeat the test one more time and then once again. These are the results of these 3 running within one hour:

powermanagement on:  3.27 Mbits/sec
powermanagement off: 3.03 Mbits/sec
powermanagement on:  5.21 Mbits/sec
powermanagement off: 5.71 Mbits/sec
powermanagement on:  8.08 Mbits/sec
powermanagement off: 7.55 Mbits/sec

Nothing I would have under my control changed so we're talking about external influences (maybe his TV set, maybe something else, who knows). 2.4GHz single antenna Wi-Fi is a shit show in crowded areas anyway (I collected here 139 Wi-Fi networks and only 14 of them are in the 5 GHz band) so why bother? But if you're interested in improving things it's a good idea to monitor at least 'iwconfig' output in parallel and always check 'Bit Rate' and the 3 metrics from 'Link Quality' line. Sample output:

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I already thought about writing a daemon parsing this data together with iperf3 performance numbers to feed into RPi-Monitor but without a controlled environment it's not worth the efforts. If you're looking for Wi-Fi performance forget about onboard, single antenna Wi-Fi in 2.4 GHz band. It's that simple. :)

 

BTW: At work we consider everything below 100 Mbits/sec as broken. But customers carrying around MacBooks expect wireless to be as fast as wired connections and Apple eases this due to early adoption of new Wi-Fi standards, 5GHz support and putting enough antennas into MacBooks so that MIMO and 'antenna diversity' do work.

Hi
The channel used in the 2.4 GHz band is important.

High speed WIFI modes are normally impossible on channels close to the band borders like

1 or 13 because the spectrum of the signal would be out of band.

Depending on the drivers used on both sides this can lead to errors of interpretation.

Huh? Care to elaborate on that? What are you referring to with 'out of band'?

 

Common knowledge (most AP owners unfortunately aren't aware of) is to use only 1, 6 and 11 where 1-11 are allowed or 1, 5, 9 and 13 where 12/13 are also allowed. The band is 2.4-2.5 GHz, channel width is 22MHz and interferences are well known. That's the reason channel 1 is specified at 2412 MHz and will therefore interfere with channel 2 and 3 (so any AP choosing channel 3 for example is set up moronically to interfere with both Wi-Fis on channel 1 and 5/6):

1440px-2.4_GHz_Wi-Fi_channels_(802.11b,g

 

In my environement with totally overcrowded 2.4Ghz band (counted 139 networks within 48 hours) channel 13 is the only reasonable choice (AP's 'auto channel' settings checks every few hours and constantly remains at this channel due to least polluted).  

 

Some details/explanations:

This depends may depend on HW capabilities and driver settings - either HT40+ and HT40- can be used on all channels, so additional channel will be either lower or higher than primary channel.

I'm assuming this is what @Ford Prefect meant by "high speed Wi-Fi modes".

 

Well, HT40 with 2.4GHz band in 2017 means normally quite the opposite: less performance for Wi-Fi users at least when there's more than 2-3 Wi-Fi networks in the same location. I dropped the idea already years ago but anyway, let's give it a try again:

 

While I consider HT40 with 2.4GHz highly antisocial (see below) I just forced my AP to behave antisocial and enforced HT40 now. Direct result: my AP is now interfering with 9 channels (4-12) instead of only 3 (11-13, see a few posts above). Now I (my AP) disturbs a lot more other Wi-Fis compared to before when it was configured to behave social (allowing HT40 only when this is the only 2.4GHz Wi-Fi available and doing a fallback to HT20 as soon as other Wi-Fis nearby are detected):

 

Bildschirmfoto%202017-03-11%20um%2013.20

 

 

As expected nothing changed with NanoPi Air and Raspberry Pi (AP6212/BCM43438 Wi-Fi/BT is not HT40 capable for obvious reasons: Wi-Fi would badly interfere with BT functionality) and also as expected enforcing HT40 on the AP led to much lower performance since now the AP chose channel 6 which is way more utilized here than channel 13 used before. So enforcing a so called 'High speed WIFI mode' on the AP leads to low speed Wi-Fi on devices in reality. So far so 'great'.

 

With OrangePi Lite's RTL8189FTV I was able to make use of HT40. PHY data rate is now reported as 150Mbps instead of 65Mbps before ('Great! Twice as much!') so let's have a look what the difference is in reality (since it's still crappy single antenna 2.4GHz Wi-Fi without MIMO):

 

With HT40 enabled under ideal conditions (50cm away from AP, rather large antenna) I get ~54 Mbits/sec on average with iperf3 and the following ping roundtrip times: 1.752/10.919/899.372/81.537 ms (min/avg/max/mdev)

 

Responsibly allowing the AP to only use HT20 (and back at least utilized channel 13) using same setup I get ~43 Mbits/sec on average with iperf3 and the following ping roundtrip times: 1.483/7.695/646.101/58.739 ms (min/avg/max/mdev).

 

So by behaving antisocial and destroying everyone else's Wi-Fi performance around (interfering with 9 channels now) I get a laughable 'stream performance' increase of approx 25 percent (not 100% as doubling the PHY rate would suggest!) while decreasing latency by the same amount (as expected). So if my application depends on low latency I get worse performance than before by choosing 'wider' bandwidth.

 

All of the above is the reason responsible admins and AP firmwares don't allow HT40 in 2.4GHz any longer (or allow it only if no other Wi-Fi utilizing the same channels is around). Since 'responsibility' means accepting that Wi-Fi uses a shared medium everyone has to compete for. If people would stop to use wrong settings (HT40 or all the intermediate channels apart from 1/6/11 or 1/5/9/13) then in crowded areas Wi-Fi performance could double for all users. Wi-Fi performance seems to be more related to knowledge of AP owners and Wi-Fi users in general and social behaviour than 'drivers' or other stuff we (Armbian) could make a difference :(

HT40 with 2.4GHz band in 2017? Seriously?

 

On a close range and if you are the only one with better equipment on both sides ... why not? Consumer router + client with cheap wireless unlikely, probably impossible in residential areas.
 

Weeks ago I got Mikrotik's router with powerful (1000mW) 2.4 AP and can provide few real world testing once next week. I can only say that it works at almost full speed/signal in other router dead spots ... with lots of neighbours AP's around.

So it should be marked as "YMMV"

Hmm... if it's 20.1 Mbits/sec with HT20 and 67.4 Mbits/sec with HT40 then obviously something else is different too (since otherwise HT40 is not able to double HT20 throughput numbers and especially not able to increase it by 3.35 times as in your example). So it's about channel settings that obviously differed (that's the reason I always also collect 'iwconfig' and 'nmcli dev wifi list' output since this reveals sometimes the real reasons why performance differs).

 

Instead of 'YMMV' we should still try to collect more information here to be able to start with an Armbian Wi-Fi FAQ collecting some general Wi-Fi resources but also SBC specific (eg. lack of TX power).

 

I tried to repeat my 'location 4' tests (11m away from AP) with RTL8189FTV (HT40 capable, 1T1R antenna) and the MIMO capable RTL8192CU USB dongle (also HT40 capable but 2T2R antenna). With HT40 enabled my AP switches from 13 (good channel) to 6 (pretty bad channel here) and results with HT40 get really horrible due to 2 other AP close to 'location 4' sitting on channel 6 with high TX power:

 

HT40 and channel 6:

OPi Lite: Bit Rate:150 Mb/s, Sensitivity:0/0, Link Quality=36/100, Signal level=68/100, Noise level=0/100, 1.20 Mbits/sec on average

TL-WN823N: Bit Rate:300 Mb/s, Sensitivity:0/0, Link Quality=50/100, Signal level=-83 dBm, Noise level=0 dBm, 280 Kbits/sec on average

 

That's how 'nmcli dev wifi list' looked like:

To sum it up: My own AP was listed with same signal strength in both attempts (52 out of 100) but due to different channels performance either totally sucked (extreme example the small MIMO USB dongle with just 280 Kbits/sec (!) on average) or looked ok-ish (either 11.6 Mbits/sec with 1T1R but huge antenna or 12.4 Mbits/sec with crappy antenna but 2T2R MIMO).

 

So it's still that users have to learn how heavily environment matters. In my totally overcrowded area enabling so called 'high speed' modes totally ruins performance since way too much other AP sit on the same channels then). MIMO and antenna diversity can greatly improve performance even if antenna is crappy (see picture below) and in case of larger distances the type and position/orientation of the antenna matters even more.

Well, high TX power might improve transfer speeds from AP to device but not the other way around (something I had to realize already but it would've been too much of a waste of time to drop all of the above numbers since 'average TX/RX numbers' don't reflect TX power settings accordingly. So that's on the TODO for another set of example throughput numbers with a device where I can easily adjust TX power).

 

BTW: Over larger distances the small MIMO capable dongle shows best results when operated horizontally (makes sense) with antenna directed towards AP. But based on dimensions of the dongle it is obvious that any large external antenna will outperform the stick regarding both TX and RX performance. With my setup it looks like this:

NanoPi A64 has RealTek 8189ETV so i have ported it to 3.10.104 to see how it would performs on the A64 arena.

For the same distance, same antenna, no walls between i got the values below:

 

  • bpi-m64 AP6212 with BT enabled:  ~14 Mbits/sec
  • nanopi a64 with RTL8189es:  ~16 Mbits/sec

 

Unfortunately i don't have Wifi on my Pin64+ to compare with, but i realized it is very hard to get the same values (average values)  in different time of the day, for instance you get lower values during night.

 

RTL8189ETV seems to have better signal strength and better performance ( ~ 15% faster ) however i have had a hard time to authenticate with some of my wifi router.

Well, adding to your experiences (environment matters, eg. time of the day, you're never alone when using Wi-Fi) three things should be added:

  • 14 vs. 16 Mbits/sec is a difference of less than 15 percent so close to 'result variation' (especially when having in mind that the maximum with this implementation (2.4GHz/HT20) is around 45 Mbits/sec --> 2 Mbits/sec difference with 45 Mbits/sec max is not even 5 percent, so maybe it would be an idea to test again with 1m distance between board and AP?)
  • It seems you only tested from board to another host but not the other way around? If so I wonder whether different TX power settings make any difference (though no idea how to influence/test this, just based on a comment from Jon Smirl on CNX)
  • I would prefer to always get the output of 'iwconfig' too since some differences in performance/observations may be easy to understand by numbers/settings listed there (eg. with powermanagement active throughput might vary a lot and end result might look lower even if specific implementation would be faster)

Hmm... really? Thanks for the iwconfig output since I was looking for this:

testing 'location 4': 11m away from my AP in neighbour's flat with 3 walls and some chimneys in between.

 

Since I ordered in the meantime this cheap dual-band/dual-antenna Wi-Fi dongle (based on Ralink RT5572, 802.11n capable, rt2800 driver in mainline kernel) I just gave it a try again and tested from location 4 only (description and results with the onboard variants see above):

 

I tested with a board using kernel 4.9 so getting Wi-Fi up and running was just the usual 'nmtui-connect' call and I were in. Please take the 2.4GHz results with a grain of salt since I don't wanted to wait until midnight for tests and Wi-Fi testing in a city in 2.4 GHz band on a saturday afternoon is almost stupid (since neighbours dictate your performance more than anything else). Test setup is as before, there's a GBit Ethernet connected machine running 'iperf3 -s' and I test from the board both directions with 'iperf3 -c 192.168.83.146 -t 120 && iperf3 -R -c 192.168.83.146 -t 120'. So there's always two values, the first one is the 'board to other device' number and the 2nd the opposite.

 

2.4 GHz: 8.21 Mbits/sec / 8.52 Mbits/sec

5 GHz: 3.95 Mbits/sec / 18.4 Mbits/sec



wlan1     IEEE 802.11  ESSID:"Snort-Honeynet 5GHz"             Mode:Managed  Frequency:5.24 GHz  Access Point: BC:05:43:BE:C1:E3              Bit Rate=26 Mb/s   Tx-Power=20 dBm              Retry short limit:7   RTS thr:off   Fragment thr:off           Encryption key:off           Power Management:off           Link Quality=34/70  Signal level=-76 dBm             Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0           Tx excessive retries:17  Invalid misc:59   Missed beacon:0

As already said results in 2.4GHz band are questionable since saturday afternoon and 5GHz results not that overwhelming when comparing with the little cheaper 2T2R RTL8192CU dongle above (2.4 GHz).

 

Since I ordered a 2nd Wi-Fi dongle that came with much larger antennas I shut the board down, replaced antennas and repeated the same test with exactly same software/setup. So from here on only antennas matter:

 

2.4 GHz: 5.65 Mbits/sec / 8.26 Mbits/sec



wlan1     IEEE 802.11  ESSID:"Snort-Honeynet"             Mode:Managed  Frequency:2.472 GHz  Access Point: BC:05:43:BE:C1:E7              Bit Rate=39 Mb/s   Tx-Power=20 dBm              Retry short limit:7   RTS thr:off   Fragment thr:off           Encryption key:off           Power Management:off           Link Quality=40/70  Signal level=-70 dBm             Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0           Tx excessive retries:1240  Invalid misc:2494   Missed beacon:0

5 GHz: 7.61 Mbits/sec / 36.7 Mbits/sec



wlan1 IEEE 802.11 ESSID:"Snort-Honeynet 5GHz" Mode:Managed Frequency:5.24 GHz Access Point: BC:05:43:BE:C1:E3 Bit Rate=60 Mb/s Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=38/70 Signal level=-72 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:5 Invalid misc:50 Missed beacon:0

In 5 GHz band the huge antennas led to a nice improvement (almost twice the numbers) so it seems that's always worth a test.

Output: with another round of iperf3, 3M from AP, just some equipment turned on around. Small antenna
