Do the usual: first, power cycle the router. Failing that, power off, remove and reinstall the SIM card to reseat it and power back on. Failing that reset the router to factory defaults! If the issue is still not resolved you may have to speak to Customer Service (800) 922-0204 about a replacement if under warranty.
