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.

- @LawrenceC - computer ethernet port and another ethernet port. Why ?

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.

  • Few households have Ethernet ports in the wall, though some newer apartments might. Jul 30, 2013 at 19:28
  • might be your new cable is a crossover cable. don't use those.
