I'm trying to get an MBR1000 Cradlepoint 4G router working, but every time I plug the 4G aircard in, the router constantly resets itself about every 10 seconds or so. If I take the aircard out, the router is fine (of course doesn't have internet connection), and I can plug the card into a PC and it works fine. I talked to Verizon, and they told me that the air card that we DID have wouldn't work with a router, so they exchanged it and gave us a newer one. The 4G card is the Pantech UML290. Any ideas on why it might be doing that? I've tried everything I can think of, including updating the firmware on the router (and the router's 4G firmware), I've reset the router to default settings in case a setting got messed up. The guy at Verizon told me that I should basically be able to plug it in and have it work.
You will not need to update the 4G Firmware Driver for your modem.
