Hello, today I've moved into my new apartment and got new internet, I'm having problems with it. When I plug in my ethernet cable it says "identifying network" and then goes to "unidentified network" when I try troubleshooting the only problem found is ""Ethernet" doesn't have a valid IP configuration". I tried calling the engineer who did all the work he said that it's 99% PC problem. I had same ISP for in my previous apartment. I would appreciate if you could help me^^
