Mi R3G WiFi not working with 22 version

Hi everyone, i'm having some issue with the Xiaomi Mi r3G and WiFi connection.
I'm using it as a wireless router with the wwan interfce connected to a wifi AP with open security.
I've tried to upgrade OpenWrt to version 22 and i'm facing issue with the wifi connectivity.

  • Version 22.03.0 gives me wifi instability as the wwan wireles connection drops lots of times during day
  • Version 22.03.1 is giving to me no wifi functionality at all (in luci there's no wireless menu)

Has anyone faced the same issue? Any advice? Now i'm with version 21.02.2 which seems to be stable enough.

here's some logs:

I'm still having issue even with version 21.02.2. Logs are in the first post.
