[PROBLEM] Losing Wifi Connection

[patrik96]

Hi, May someone face a same problem and find the solution,

I was change the PI4 to PI5 because think it hase stronger wifi amplifier, what I need because the PI vs router distance is 7m and the signal strengh is only -68-70dB,

After changing the setup goes well no problem, the 1st rebbot is quite normal, but after no WiFi connection,
I try to put 1m further the PI nothing, the LAN is OK, and after LAN connection again search the WIFI and connect it is OK, if unpluged the LAN working good, but if reboot, no connection again,

Thanks
