I have the 24 port Cloud Router (CRS125-24G-1S-2HnD-IN) and would like to setup a backup Internet access using the MiFi® 4G LTE Global USB Modem U620L from Verizon Wireless. This is not listed in the compatibility list. Has anyone successfully used the U620L from Verizon? If not, can anyone suggest a good solution for a wireless backup WAN to use on the Cloud Router?
