i have an xbox 360 and wireless network adaptor. i have a pc which is linked up to a netgear Dg834g router and a laptop with built in wifi. everything has been working fine for a year, internet on my pc, internet on my laptop and i can get on live on the xbox. Now i cant get the internet on my pc, i can on my wifi laptop (i thought this was strange) and i cant on my xbox. the xbox says that it cant obtain an IP address, anyone have any suggestions what-so-ever?
