[Lamobo-R1 wifi unstable in AP ("host") mode [better buy a good wifi dongle with proper linux support]]

Many thanks Rui for this.  I have a silly question, but do you build on the Lamobo or under Ubuntu like Igor describes?  I cannot get the build to work on my Debian Jessie PC so I will make an Ubuntu dev environment over the next few days to try this out.

Hi, 

just out of curiosity, did you run Step1, it is in my manual:

 

// Step 1 //

scan networks: iwlist wlan0 scan

show available channels: iwlist wlan0 channel

find least used channel: cat /proc/net/rtl819xC/wlan0/best_channel

First, thanks Tido and ruir and sorry for not responding earlier -- I was in need of a working solution so eventually had to use a different device, but I would like to get back to this now.  I did scan for the least-used channel and tried that, but I still needed to do enable_wmm=0 in order for it to become stable.  I also watched the signal strength and without this it was unstable, so my feeling is that it's something to do with hostapd, however I couldn't get a build environment working (on Debian Jesssie) and I don't want to get into Ubuntu just to build Armbian (perhaps when I have more time).

OK a quick update -- I got this working stable with only one change in /etc/hostapd.conf -- wmm_enabled=0

This apparently disables "wireless multimedia" which I think is a kind of QoS.  Either way I just want a basic, stable g and this works for me.

Hi Everyone and thanks to Igor and all who contribute!

I'm also trying to get R1 WiFi stable, I have compared this with the latest OpenWRT V4 image from 01/09/2015 on banana-pi.org) and that does have a stable WiFi (not great, but stable) so I'm trying to figure out where the differences are.  I haven't been able to get the alternate driver for the Armbian Jessie image working but I'm not sure of all the steps to make the change .... just changing hostapd.conf and hostapd to the -rt versions does not seem to be enough -- do I also need to blacklist the kernel drivers?

I will put a build environment together this weekend so I can play a bit more but any advice is wecome.  That OpenWRT image proves the hardware is good enough for my needs but I want to run Armbian for other reasons.
