Hi,
I've been struggling to connect to the eduroam wifi for the past week on my laptop. I ran the cat installer tool to setup the connection settings and that worked fine. I use NetworkManager either with nmtui or plasma-nm. The problem is NetworkManager tries to connect to the wifi and it asks me the password multiple times without ever connecting.
Sometimes the wifi shows up as connected but I can't access anything on the internet, let alone ping google.com. I've tried switching from networkmanager to networkmanager-iwd without much success. Sometimes the wifi works but then it stops working.
The driver and firmware seem to load correctly, I've fixed an issue where to firmware failed to get out of lps state, but I still can't connect to eduroam. I believe my connection settings are fine, they are from the eduroam cat installer. I'm beginning to think there's a problem with my arch installation or my network card.
My network card is Realtek RTL8822BE. I have a decent experience with linux and arch, but I believe this is out of my range as far as troubleshooting and fixing the problem. I hope you can help!

Update:
Eduroam seems to be working today, which is weird because most of the time it doesn't. However, I tried pinging google.com and it didn't work at all. Everythint else works. At home, on my own wifi, I can ping with no problem. I hope there's a way to have a stable connection to eduroam so everything works out of the box everytime I connect to it. Thank you.
