Mac Forums

All of a sudden i cannot connect my MacBook Pro to my home wireless, everything else in the house can connect fine it is just my Mac that i am having problems with, the wireless is showing up in the airport but stating no ip address. I have phoned Apple (UK) and spent 2 hours on the phone with them only for them to be completely stumped and say they have never heard of this problem before, i am hoping someone can help me please!!!
