Modem manager interfering with Wifi?

Installing and Using OpenWrt
1

I recently built a new version of OpenWrt from source and I keep seeing hotplug events with related to my inbuilt WIFI and lan and modem manager should not touch them I believe just WAN and WWAN?

I tried disabling modem manager and rebooting my router my WIFI and lan seemingly starts working but I don't know something is weird..

Did you find a solution to this? I am seeing the same.

I think this was a red herring / coincidence in honesty and it has something to do with my bridging with purely WIFI interfaces.

I have ath10k chipset and it seems some people have problems with it if the bridge is not initialized before the WIFI is up and just happens on some devices causing the WIFI not to work.

Suggestions was to change to alternative WIFI firmware, small buffers and or switch from CT to non CT firmware but nothing fixed this issue

My solution was to add a sleep command to the rc.local file in root/etc as below:

sleep 10
wifi

exit 0
