WIRELESS QUESTION

[TEXASGUY]

We got my fathernlaw a laptop for Christmas, he works on gas wells in east Texas and wanted to play poker on the job. We went to cingular and got the card for their service. When we hooked it up, we kept getting disconnected. Is this just the service, or does the computer speed figure in? I see the commercial that says sprint is up to 5 times faster than cingular, is this the same thing? The computer is just a 256, does this figure in? Any help would be greatly appreciated.
