Windows 7 media centre won't connect to xbox

[Markfcc]

Hi there, I've recently changed my pc connection from wired to wireless and now my pc is unable to communicate with media centre on my xbox! I've allowed media centre extenders on my windows firewall and still no luck. I've tried turning the firewall completly off and turned off all security on my router any ideas? Thanks in advance

On your PC, in WMC remove the extender from your PC. Then on your Xbox, remove it from being an extender, then set it up again from scratch.

Thanks for the reply I tried that already if I go networks it sees my xbox but won't communicate! Any ideas
