Random Route Change - D600 with Broadcom Wired and True Mobile 1450 Wireless

Been working with Juniper Networks to troubleshoot a problem with their SSL VPN solution, using their Network Connect option. The symptom is this - when we launch their Network Connect component to establish a tunnel (either via wired or wireless) the connection randomly is dropped with the error message "Route change detected". So we start doing "route print" to watch what is happening and catch the D600 inserting one or the other network adapters in to the OS routing table - but it has no IP address, just shows up as it would in the "Device List" you see at the top of the data displayed by doing a "route print". So this device gets inserted randomly, has no IP address, and is causing the SSL VPN software to freak out - it just knows the route on the OS is changing and that's a no no.

 

Thoughts on how to resolve this other than disabling the network adapter not in use (which for the most part solves the problem but is not really something we can rely on our users to do always).
