Wireless issue every 3-4 days. Need to reboot #32

Hello,

I have an annoying issue with my Archer C7 with your latest stable release. Everything was working fine after the installation but then 3-4 days later, I had no more Wi-Fi and I had to unplug/plug again my router for getting back the Wi-Fi working.

Nevertheless the LAN with my PPoE was still working but the WiFi not.

Would you have some ideas for this? :blush:

Thanks for your help.

Regards,

SuperITMan

Can you post the output of dmesg (Kernel Log)? I infrequently have a similar issue where just my 5Ghz radio crashes on one of two C7s I have that are running a fork of this firmware. I have even tried compiling with a newer ath10k driver but get the same result after awhile. I think the issue may be due to a certain troublesome client rather than something with the router firmware, however I am not entirely sure.

EDIT: ath10k and 802.11w are currently bugged, details. Restrict usage of 802.11w to the ath9k radio only.

I've had the same problem. I found a post recently suggesting that disabling Distance Optimization on the wireless radios fixes it. I haven't had any problems since disabling that, but it's only been three days.

@lymanepp Is this still working for you after disabling distance optimization?

nigelhooper commented 6 years ago

I am currently having the same wifi drop out over 2.4GHz (not using 5GHz). In LuCI I don't have any distance entered for the Distance Optimization - I assume this means it is disabled? Quick question which radio should I use for 2.4 and which for 5GHz i.e. radio0 or radio1?

One thing that might also help is disabling disassoc_low_ack as mentioned here: https://github.com/enyone/tplink-archer-c7-openwrt/blob/master/README.md#update-nov-17
