Using a usb730l modem attached to a cradlepoint mbr1200b router. Had this setup for a year now with no issues. The other day, we couldn't connect to internet. The router says there's an issue with the modem. Plugged modem into laptop, went to Verizon's myusb page (192.168.1.1) with browser and it won't let me connect to Verizon network because page says there is no sim card. Well, yes there is a sim card in the modem - I popped it out, put it back in and the page still says there is no sim card. So what do I do now?
