Radios go offline

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi, I have this router:

Hostname	ArcherC7
Model	TP-Link Archer C7 v2
Architecture	Qualcomm Atheros QCA9558 ver 1 rev 0
Target Platform	ath79/generic
Firmware Version	OpenWrt 23.05.5 r24106-10cc5fcd00 / LuCI openwrt-23.05 branch git-24.264.56413-c7a3562
Kernel Version	5.15.167

After 10 days of work all radios went down, here is the log:

The router is parametrized as dumb AP and normally serves two WiFi devices and one rj45 (that was not connected at the time of failure).

I think, but I cannot grant, that this did not happen in 23.05.4 and earlier. What can be the problem ?

Likely changing ath10k kmod and firmware to -ct or vice versa can help.

No problem in your config. Lets try to change wifi driver.
Please post

opkg list-installed | grep ath10k

Here it is:

root@ArcherC7:~# opkg list-installed | grep ath10k
ath10k-board-qca988x - 20230804-1

Done. Hope that this is the solution. I will mark as a solution after 2 weeks without problem.

Many many thanks.
