I need help. I have DSL Lite through AT&T (formerly Bellsouth), and I want to put a wireless router onto the modem so I can use the internet, and use a wireless adapter on my XBox 360 to get onto XBox Live. What I am wondering is 1: What router will I need to get so that it is compatible with my Westell 6100 AND my XBox 360 wireless adapter, 2: How would I go about setting up the wireless connection, and 3: Will the addition of a wireless router increase my monthly billing from AT&T?
