Since some months my phone needs several seconds to start operation, when I switch it on. There is no WLAN icon in the top line, and often it tells me, that there is no WLAN connection:
After “activation”, the phone reacts rather smooth, I guess “normal” (for an FP3+ 
).
My Android 13 has Build-No. 6.A.039.7, I have 15 GB free space out of 64 GB.
The problem is independent of the strength of WLAN (2,4 GHz and 5 GHz); I have several access point at home:
I tried already to deactivate 5 GHz, 0r to deactivate the Fritzbox-mesh, no success.
Any idea?
