I have a Dell Inspiron 2500 connected to a Verizon VX8300 cell phone via USB. The phone accesses the internet properly under Windows XP using VZAccess Manager.

I am using Knoppix Live CD version 5.1.0 and have configured the Kppp dialer so that I can access the internet using
/devttyACMO. I tried the other modem options but I could not connect to the internet at all with them.

My problem is that the internet connection only works for about 2 minutes. Then I get the following message:

"pppd daemon died unexpectedly. Exit status 15"

I would appreciate any advice I can get that would help me understand my problem and hopefully suggestions to make whatever changes are needed to fix the problem.

Thank you.
Arthur
