Toggling Network on Motorola Q

I'm building a Jabber client for the Moto Q and am having issues with the "network" interface turning off on the Q. When the "network" connection is on, my app works fine. When it goes down, I get a "dead network" error.

Is there a way with .NET CF to turn the Windows Mobile 5.0 network interface on I've checked the Moto site and can't find any reference to this. Thanks...
