I cannot connect to the internet via ethernet cable, but I can connect via wifi. Also, my computer does not switch to ethernet. I can still see the wifi. How do I find the source of the problem and fix it?

change adapter settings in windows network settings. The realtek ethernet adapter was disabled. Enabled it and still no ethernet.– bashboyJul 30, 2013 at 19:03

Sounds like you are in a campus or office environment.
If nothing else works when connected to that Ethernet port:
- The port in the wall may lead to a patch panel in your computer or telecom room which is not connected to any switch.
- It may lead to a switch that is powered off, faulty, or incorrectly configured.
- Some enterprise level switches have "port-security" that only allow a specific MAC or the first MAC detected to communicate on the network. There won't be a way for you to find that MAC out from the port.
- There may be issues with the cable in the wall
- There may not in fact be a cable in the wall leading anywhere

Thanks. Yes, I work in the kind of environment which you described. Yesterday, I connected to the same port using another ethernet cable. It was working. Now, I am using a different one. Its unlikely that the wall port is not working.– bashboyJul 30, 2013 at 19:26

Few households have Ethernet ports in the wall, though some newer apartments might. Jul 30, 2013 at 19:28
