Devolo 1750c/i unstable/stops routing

Installing and Using OpenWrt

Hi, I use a lot of Devolo 1750 series AP. They were dirt cheap some years ago and offer a decent performacen.

however starting something like a year ago they started to drop of the network from time to time. It doenst matter if they are powered over POE or standard power supply.

usally it shows, that they still provide the WIFI but no DHCP requests are forwarded. Also the AP itself is no longer available over IP (I configured the APs also with Client DHCP.

I tried upgrading and downgrading but to no avail.

On some platforms ath10k kmod+firmware from mainline or candelatech works better than other, like radio not crashing, or totally good speed etc.
If you want precise command line to replace show

ubus call system board
opkg list-installed | grep ath10k
