It wasn't a fix on my end, rather they had to manually create my account on their end, and they did it wrong (didn't properly enter the WiMax MAC address from my device to my account). So they made a new account, and credited me the amount I paid for the old account.

Also, while driving around yesterday, the signal would drop a lot. I started from Sefton Ave (northen part of the city) and headed down Hartford Road to North Ave, then to Howard Street, then to MLK Blvd, then to 395S then to 95S, and the signal was gone for good about a mile from the City/County line, which I figured. But I didn't think I would have to reconnect to WiMax every 3 minutes or so. Also, there were a lot of dead spots along Hartford Rd about 2 miles from North Ave. I don't know how the others who reviewed Xohm with a laptop and express card were able to get solid signal while driving (I think it was Laptop Mag that said this).
