Tethering problem

[DumbDumb]

Ok so.. I installed a custom Rom that had the tethering option(internet sharing) and it would never let me connect, So i down loaded another program in cab that was supposed to do the same thing.
Well it worked sorta.. Device and comp say it connects but no internet on my comp?
I have been able to load up Google threw fire fox for a split second then nothing after that(if i search or put in a different address it doesnt load.. and i go back to the offline connection error page..)
Any body have this problem? and know how to fix it?
1. I'm on metropcs
2. Ive installed 2 programs that let me sync up to my comp.
3. could it be the multiple programs?
4.my touch pro is the sprint version with a verizon radio.

Thanks in advance and yes i have searched before posting.
(thanks to my homie ray for letting me use his air card to try and fix this problem!!!)
Hurray for him going camping!
