Have got BT Business Infinity on 300/50 GFast.
The 4G assure dongle came in a separate box, which has never been opened, and the BT Business Hub was switched off once the OpenReach technician had left to be replaced with the GFast modem plugged into my own router instead.
Having had an annoying temporary outage for a while at a particularly inconvenient moment, I've now decided that a failover would be a good thing. So...
- Can the SIM from the 4G assure dongle be extracted and stuck in a separate 4G Ethernet modem for my own router to failover between? Or is it locked to only work with the BT router?
- If the dongle only works with the BT router, can the BT router be put in a Bridge Mode, with the GFast modem plugged back into the BT router, and then the the Bridge output from the BT router then goes into the WAN of my own router which then doesn't know the difference between that and today's setup where it has the GFast modem directly plugged in?
- When it's doing failover, how quick and how sticky is the BT router? Does it wait for a 10 minute outage, or would dropping ping for 1 minute trigger it? And how quickly does it come back to DSL once it's back online?
- Whilst the running on the 4G assure, do I keep the same static IP address? Or does it temporarily have another IP address until the DSL comes back?
Does anyone have any experience of using it generally?
