my ethernet was working fine for some time and then started like switching between trying to recognize the network and saying that the ethernet cable isn't even connected and after some time it would connect and everyhing is fine, but now it's doing the same thing but it doesn't recognize the network at the end, network tester says that it should work just fine and my pc has no problem with connecting to other ethernet outlets(with 10m ethernet cable to another room) but it's not working with the one at the same room..
