I have recently did a full reinstall due to having lots of packages I never used and since then I have been having severe network issues. I have to spend several minutes turning wifi and ethernet on and off until it finally registers it and connects. I never had issues like this before reinstalling so I think it may be due to a recent update but havent been able to pinpoint anything
Did you take a look at your logs? You should find some information in there as to what’s going on.
I think the real mistake here was doing a re-installation “because of packages you don’t use”. It would’ve been more worth your time to learn how to remove the ones you don’t use so you can better understand how to organize your system.
