AT&T Cellular Problem

The nvidia geforce 8400 chip in my Dell XPS M1330 recently died.  It was under warrenty, and Dell promptly sent over a technician to replace the entire motherboard.  The tech did a fine job, and the computer is generally working well since this time.  In this computer, I have an internal cellular modem.  When the tech was reconnecting all the parts back together, there was one issue.  The cellular modem was not functional.  The error was that there was “No Sim”.  We promptly opened up the modem/wireless access panel, and checked the connections.  After, a restart, the modem was working again.  All seemed well.  I even used the cellular connection a few times over the next couple of days.

Then on March 17, 2009, the connection died.  I am not sure what is going on here.  The behavior is very different that the No Sim error.  This time, the computer can not find any connection, but it knows all is working.  The card is detected, and the Sim is indeed read, and has all the correct information.

I called AT&T to ask them if there as some somethign going on.  I was told that there is indeed an outage of sorts in my local area (NEW YORK CITY).  I asked the agent (who was very nice) if she could relay me the details of the problem and she basically dodged the question and said that it would be fixed by 5 PM.    Its now 9:30 and the problem is not resolved. I am completely clueless where this problem is coming from.

I think the main problem I am having here is that AT&T didnt tell me the source of the problem.  I should also say that this service costs $2 per day and its been out for 2 days now.  I don’t know what to do at this point, but I am making this post in the hopes that someone else is having the same problem and will find this message.
