hello linuxlover.chaitanya.
The results of your last post requesting the results of iwconfig are below. I think it says the access point is not associated. I have no idea how to do that. Virginbroadband can not help,they have no experience with ubuntu. A technician I talked with did not know how to fix it, but did say, if i could fix it I would have the best system out there.
