Ok, so recently I purchased the Pantech UM150 Air Card through the Verizon Wireless network because I needed a substitute for a hard wired network in the dorms I'm living in. The biggest reason for this was online gaming, but no one on the internet seemed to know exactly how it would work out. I purchased the Cradlepoint MBR1000 router to allow for a WAN, and hard wired that to my Xbox 360. A few problems had to be worked out, but now I'm as happy as ever with my decision to go this route. I've played Halo 3 online for close to 3 hours just today, and I never had ANY problems with lag. So for you out there thinking whether this can work or not, I am telling you it can.
