On other interesting point is that settings for the mobile data context are a bit odd in that the gateway and address returned from the operator are both the same:

Interface=ccmni0 DomainNameServers=149.254.230.7,149.254.192.126, Gateway=10.129.20.112 Address=10.129.20.112 Netmask=255.255.255.0 Method=static

This doesn't appear to cause problems when the mobile data connection is initially configured, however for some reason when WiFi is disabled it is causing an issue.

On initial configuration, we setup up the route for mobile data and then set it as default.

When WiFi connection, we setup a route for WiFi, then make it the default route ( ie. we don't remove the mobile data route ).

When WiFi is again disabled, we remove the WiFi route, and attempt to set the mobile data route as the default again. It's during this logic that the failure occurs.
