Not sure how to get the hardware version as I don't see it, but I have a Verizon LTE GateWay that I used to have as a backup to my Unifi but that Unifi router died, so I am looking and can't see if this XE75 supports duel WAN.   There are several pages I have read about load balancing etc.

Basically I want to keep my 1G Fiber as the primary, and if that fails, to just switch to that one, so is that possible?

Thanks
