  1. Check TCP/IP Properties.

    Start, Connect To, Connection, Properties, Scroll Down TCP/IP and highlight, click Properties and check that Obtain DNS and IP address automatically are enabled.

    I have checked this already and it is set to automatic, I have compared my sons wireless connection to hers and they both seem to be the same, unless I have missed something?
  3. I have thought about using system restore to a date when it worked , would this work?
