I am working on a project where I need to connect my RPi 4 to a laptop hotspot. Everything was running OK when I had Ubuntu 18 LTS installed on laptop. After I switched to Ubuntu 20 LTS, RPi 4 won’t connect to it.
I tried connecting RPi 4 to other Wifi networks and to hotspot created with Ubuntu 18 and it worked flawlessly. I tried connecting RPi 3B to the same Ubuntu 20 LTS hotspot and it worked to. So only RPi 4 won’t connect to hotspot with Ubuntu 20.
I am running Raspbian headless and I tried reinstalling it and still doesn’t work. Tried switching a Wifi channel hotspot is running on and no luck. Since I have only two RPi 4 I tried with both of them and got same results.
Does anyone have any idea what is happening?
Where is best to look for some Wifi log files?
Appreciate any help.
