I've been able to configure the USB DUN for my ppc-6700, however I lose the connection after a minute or so. The strange thing is that my computer still maintains an ip address, but I can't ping any other ip's.

Before the disconnect I definitely have a connection as I can hit internet sites.

Does anyone have any ideas as to why I am getting disconnected and what I can do to make it more stable?
