I just upgraded from a NEXTEL 7510 to a 7520, both were running the latest OS. When the 7520 starts up, I do not get a "network" connection in the top corder, then I get a full strength connection (all bars) but the "nxtl" stays lowercase, then the radio resets and I have no connection, then the process starts all over again.

Any ideas on how to fix this? Needless to say all I really have now is a paperweight with GPS.

Thanks.
