AR9271 random freezes in AP mode when distant client is connected #137

Open rlking opened 7 years ago

rlking commented 7 years ago

I have a RPI 3 with raspbian stretch using a TL-WN722N in AP mode with 802.11n enabled. It runs stable for days until I start connecting to it from a distant room, then I get unpredictable freezes within hours and only physically detaching the stick fixes the issue. I tried most of the 4.9.x kernels and also 4.12.x but it doesn't make any differene. I'm not sure if this is kernel/driver/firmware related.

Here is some output

If you have any suggestions how to further debug this just tell me.

Kind regards

It would be really interesting to get log from firmware. Can you solder and have some experience with UART? Here you can find info about this chip https://wikidevi.com/wiki/Atheros_AR9271

rlking commented 7 years ago

I will look into this, I should have everything

rlking commented 7 years ago

I bricked it while removing the internal antenna 😔

olerem commented 7 years ago

In case you still wont to play with this chip, i would recommend this model https://wikidevi.com/wiki/ALFA_Network_AWUS036NHA it has accessible uart pins and external antenna.

olerem commented 7 years ago

For RPi users, if you find a way to power cycle the usb port, there should be no problem to reset the usb adapter. Some thing like this https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=93463#p651809

I have a really similar issue with AWUS036NHA in Ad-Hoc mode on kernel 4.15. We are using a network of around 8 devices connected to NUC PCs in our tests. Every time a device disconnect, other devices have a chance to crash. I reproduce it by rebooting one of the PC and eventually other devices start crashing the kernel thread freeze on those crashed nodes.

Here is the kernel log:
