I have 2 Archer C6 v2 routers, connected via Ethernet. One of them has this problem where every few days or even hours Wi-Fi completely stops working, but devices are still connected. They can't ping any host or the Internet. Running wifi on the AP temporarily fixes the issue. I've tried everything I found online (setting WPA rekey to 600, enabling multicast to unicast, downgrading to 22.03) but nothing worked. Sometimes the Wi-Fi breaks for a couple of seconds then comes back on its own. What baffles me is that it only happens on one AP, it never hapened on the other despite identic configuration. I'm tired of having to change settings hoping the issue will go away - I just want something that works without having to reboot everyday.

I'm using ath10k
Happened again. Wifi went down for a couple minutes (couldn't reach the router at 192.168.0.1, but still connected) with this error repeating in the logs: ath10k_pci 0000:00:00.0: failed to flush transmit queue (skip 0 ar-state 1): 0
