Ever since the last major update a while ago, I have been unable to make a connection via Ethernet to my broad band router. When I look from the network panel on my desktop (Plasma) I see it attempts to set network address (to get one for itself from the router for the internal network?) and after a 5 seconds or so, it cuts the connection and starts a new attempt.
First problem I had after the update was that my Realtek Ethernet adapter’s driver had vanished so I had to reinstall it. Connecting through USB via my phone works fine. On the Windows side of the dual boot, there are no problems. Some times the Ethernet connection starts working either in a limited capacity up to the router but not further, in a full capacity but slow speed, or even in a regular manner. Seems to consistently happen around 1h 30min uptime mark, not always though. Switching kernels does not solve the issue.
Oh, and it’s a pretty old Inteno router (around 7 years), I can check the exact model when I get home if some one needs that. I’m out of ideas and would be happy for assistance.
