Problem with hostapd & ALFA AWUSC036AC

Ireng · July 21, 2015

Hi to All!

Currently i am using 3.4.107-cubietruck #14 SMP PREEMPT Wed Apr 29 11:57:42 CEST 2015 armv7l GNU/Linux including a WLAN USB Adapter AWUS036AC from ALFA.

First question: Does anybody got this adapter to work with a cubietruck as a WLAN-AP?
Second question: If yes, what driver did you use for the successful implementation?

Third: How to disable the onboard WLAN?

I want to use it as a 5GHZ (AC-standard) WLAN-AP!

Many thanks in advance.
Regards, Ireng

I have similar (Realtek 8812AU chipset) but haven't got far yet.

Most promising driver, not sure that AP is operational and stable @5Ghz.

Hi Igor,

thank you for your reply and support!

Since I opened this subject already twice on cubieforums.com, I thin we should discuss the issue here and in the other two threads should refere to her!

I tried the ALFA driver, and it is a complete mess. Currently I try get the adapter to work with the rtl8812au-linux driver. However, I'll give your reference https://github.com/gnab/rtl8812au a trial as well and will report back here later.

Thanks for your help, support and references. I'll keep this thread updated!

regards, Ireng

Hi Igor,

at the moment the WLAN AP is working in 802.11.a mode(5 GHZ) including the current installed driver (rtl8812au-linux).

However I still can not connect with my TAB S or Glaxay mobile phone.

/usr/sbin/hostapd-rt /etc/hostapd.conf-rt starts the WALN-AP.

Please have a look at the enclosed hostapd.conf-rt, maybe I made some mistakes or overlooked an option:

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
interface=wlx00c0ca8184e0
bssid=00:c0:ca:81:84:e0

#ht_capab=[HT40+]
wpa_key_mgmt=WPA-PSK

wpa_group_rekey=86400
### hostapd event logger configuration
logger_syslog=127
logger_syslog_level=2
logger_stdout=127
logger_stdout_level=2

the strange looking WLAN devices name was derived from the driver rinstallation.

ifconfig results into the following output:

Hard to comment on this. If you can't connect it's not working Try open mode - without password. The config looks fine but I guess the driver is probably not capable of AP @5Ghz Try the suggested driver. I think it's the best we have than check / open an issue.

I know. Pity

P.S.

I have two sample hostapd.config for my hostapd binary. Have you tried that?

/etc/hostapd.conf-rt

and

/etc/hostapd.conf

Ireng · July 24, 2015

Thanks, Igor for your advice.

Checking the MAkefile I found 2 otions for the ARM Architecture:

CONFIG_PLATFORM_ARM_SUNxI = n
CONFIG_PLATFORM_ARM_SUN6I = n

Which one is the right one for the cubietruck to set??

Thanks in advance for your advice!

regards, Ireng

Igor · July 24, 2015

Very simple You don't need to edit anything.

git clone https://github.com/gnab/rtl8812au
cd rtl8812au
make ARCH=arm
insmod 8812au.ko

Plug-in WiFi adapter and voila.

AP mode @2.4 working out of the box, I can try 5G tomorrow.

Kernel is 4.0.5, board Orange Pi.

Can you paste your network configuration. Maybe there is a problem?

Enclosed you'll find my network configuration from /etc/network/interfaces:

Cubie5 is the system in trouble! :-)

Ireng · July 25, 2015

Now the Infor in the router changed (without my interaction)

But still no access to the net!

Ireng · July 28, 2015

Hi Igor"

Did you have a chance to look at my last postings?

Regards, Ireng

Igor · July 28, 2015

Not much but look what I did.

- latest fresh image 4.1.2

- git clone https://github.com/gnab/rtl8812au

- make and load driver

- use default hostapd-rt.conf and hostapd-rt binnary

- use interfaces.hostapd

it works normally. Not tested for 5ghz.. busy @moment.

Ireng · July 28, 2015

Hi Igor!

Thanks for your support. The current configuration and driver shows a 5 GHz WLAN available. The only problem is, that I can not connect from my mobile phone or tab to the AP. It always refused the connection. Perhaps a misconfiguration of the network?? The mobile devices are ac capable devices.

Regards, Ireng

PS. The reason why I want to use 5 GHZ network is because the 2,4 GHZ is over crowded in my location. Nobody is using 5 GHZ.

The reason why I want to use 5 GHZ network is because the 2,4 GHZ is over crowded in my location. Nobody is using 5 GHZ.

I am having a similar situation but failed to find appropriate / cheap 5Ghz AP. I own three dual band wifi devices (2 x mPCI 1 x USB) and this one is the only one that it (almost?) work. Others, Atheros 9382 doesn't work at all and Intel 7260AC simply does not support AP in 5Ghz.

You'll need to ask driver maintainer for additional help & tips:

Hi,

is there any progress / good news on this issue?? LINUX -Driver, etc.??
