Personally I have a cable running to my Xbox 360. I was thinking about getting the wireless network adapter but am unsure what the connection will be like and if I will have any lag. The last thing I want after spending 100 bucks is to find it not working. I have a wireless router in which I use my DS and PSP no problem. I will wait and see if anyone else has any problems with it. At the moment though I am more than happy with my cable but is a bit of a pain because of the 20 foot cord running from my computer room to the living room. If anyone has the wireless network adapter please let me know. Thanks
