We have multiple computers in our house running Windows 7 and one running Windows 8. The windows 7 computers have not been able to search for updates since mid 2012. The laptop running windows 8 is brand new and is doing the same thing. When we connect the windows 8 to internet connection from a mobile phone it works.
We have a linksys WAG200G modem/router. Could there be settings in the modem/router that could be bloccking windows updates? I think some settings may have been changed when setting up teamspeak server. Can anyone help please?

Thanks
