Disabled the DSL path as we don't have a phone line near us. Got 21Mbit/s from an O2 High Speed Downlink mast nearby which is pretty much capacity for this type of mast and running Giffgaff Sim. Using an external aerial 15 + 15 dBi and 10m of supplied coax and two TS9 to SMA tail leads ty-wrapped to the modem body for strain relief. Simple to setup and very quick
I had a few issues updating it at first (you have to be in the right mode for it to work). But once set up it is decent performance for the price paid. I have it in bridging modem with a unifi router. I briefly tried failover mode, but did that through the router in the end as I had some issues.
Excellent solution for fail-over connection if you really need it. In my case is required because of all smart things around the house including the alarm system, now this (plus an UPS for power redundancy) will keep the network up even in case of broadband outage. Easy to setup, good documentation.
