I am trying to hook my Xbox 360 up through my laptop computer using its wireless network system into a pay by month service. I had it working and was able to play Xbox Live. Then it stopped (I'm sure due to my intervention). One of my computer friends found a virus in the command structure and we wound up wiping the hard drive and reinstalled the software.

I am running XP Professional, Media Player 11, Service Pack 3, & McAfee protection programs. My Xbos is plugged into my computer via a CAT 5 cable. Xbox service told me Service Pack 3 was the problem. I removed it and installed Service Pack 2 but lost my sound drivers. Even after turning off McAfee, my Xbox states it is not connected to my computer. I’ve tried matching the IP address off by one for the Xbox. Still the Xbox does not recognize my computer.

I have reviewed most all of the other posts on a similar topic but found nothing matching my situation.

What am I missing/doing wrong?

Thank you in advance for any assistance!!!
