My connection speed seems to be limited using EVDO/UModem card. 
 
Any assistance would be greatly appreciated.

I have successfully connected to Sprint network with:

PC5740 -or- PC-5740
PX500    -or- PX-500

using UMODEM driver and "ppp" but speed is about a quarter of the speed 
I get when using the card on a WinXP system.

Any help you can provide will be greatly appreciated!
