Dear Ubuntu community,

I'm a Linux newbie and I'm facing the problem of not being able to connect to the network via wifi or ethernet with a System76 OS (Pop!_OS 22.04 LTS x86_64). Any other mobile device, i.e. a Mac, a Windows desktop machine, a Iphone ect. however is able to connect to any webpage that comes to my mind.

I am struggeling with this problem for quiet a while now. I already searched the internet for a solution, i.e., I considered different dns settings, firewall issues, different browers (chrome, firefox), I changed the MAC adress of my router, and played around with IPv6 settings.

I found that if I ban Firefox from using IPv6 addresses, even becomes unreachable.

Maybe you can help me out here, since I am quiet desperate right now, what to do next.
