It can still be a issue with the network card and the router. Could not be communicating correctly. No matter where it is located. Could be incompatible. Could be there is a glitch in the firmware. I have had routers that wouldnt never work on my machine but work fine for others. Does that mean something is wrong with my machine? No cause it worked fine with a router change. There was just something about that router that didnt work with my setup.
