Eduroam unstable

Hi everyone,

I have to use Eduroam at my Uni and with my older laptop (also with linux) there was no problems.
However, with my new Legion 5, Eduroam is very unstable (sometimes works, sometimes any website is unreachable (but I can still connect)).

At home such problems does not exist. I’m on a fully updated (including kernel) Manjaro install.
