I am now getting a differnt message in the diagnose/repair box.
It says "turn off the TCP setting that is not compatible with your router."
When I click on it it says the problem has been resolved. I then re-started the computer as it was still not connecting.
it did not connect so checked the diagnose/repair bit again and it said: "turn on TCP performance improving settings" I clicked this but still no connection. Ran diagnose and it syays the first one again!! (turn off tcp setting....)
