Hello, been fighting with a getting a MC7750 to connect to verizon 4G properly. i have it hooked up to my laptop over a USB adapter case, and running the sierra software and VZWaccess manager and neither can get it to connect to 4G, all i ever get is edge. It’s not a signal problem im running a large antenna and a booster. Tried talking to Verizon and they said everything is all good on their end for the sim card. kinda stuck on what to do. i think there might be a problem with the card since everytime that VZWaccess opens it offers to upgrade the firmware.
Thanks for any help!
