You need to use either a loopback jack or a snifter for this job.ġ. Your next step is to test the wall jack, which is the most important part of an ethernet connectivity test. Repeat the above steps using the “LAN 2” if applicable. Open a web browser to see if you can do something that requires a connection.Ĩ. You need both green lights to ensure connectivity.ħ. Check for those green lights above both the WAN and Lan 1 ports on the Ethernet switch. Plug the ethernet switch power adaptor into a wall outlet once everything has rebooted.Ħ. If you don’t do this, it may not recognize the ethernet switch at all.ĥ. If it doesn’t have one, unplug and let it out of the power socket for a few seconds before rebooting.
