Hey there Ahmad, I just wanted to tell you that I've already went to that site from before, and I also did the same right now, and you aren't posting anything other than the obvious facts. Yes I do know my DSL modem's details, and I don't have to be told more than once :)
I need a way, that someone may have experienced from before, for connecting to the internet while running on Ubuntu. Keep in mind, having a DSL modem, not a router/wireless.
Thanks.

By the way, the steps you provided are for WINDOWS XP and not UBUNTU. I clearly asked for ways on Linux.
Believe me, I already called Q-TEL for such support, and once a guy asked for the spelling of the word!...
They couldn't provide any help except advising me to buy a router/wireless, or keep on searching the net - which I have been doing from the beginning of the year.
