Having a few issues with broadband dropout; my router can take a USB LTE modem for failover so contemplating this.
Can someone explain to me how it works? If I was mid-Teams call and the broadband dropped should things switch over seamlessly?
Thanks!
Well, first up, the solution to broadband dropout is to get your ISP to fix it, assuming it's not an issue with your house wiring.
In the Cisco world there's a thing called IP SLA. Basically you set it pinging (say) Google and if that ping fails for a given period of time then the routing switches over. This isn't instantaneous though - I think the default time-out for failover we set on our branch routers is three minutes.
This is on routers costing anything from £500 to thousands, quite how it would work on a cheap home router I don't know.
Thanks, it’s unlikely it’s the house, and the up time with previous ISP was weeks. I’ve been on to current ISP this morning who are working on it.
If failover takes minutes on enterprise then I doubt there’s much point in me exploring further for home as the dropouts we’re having mean that by the time it connected to LTE the DSL will be back up…
Get a dual wan broadband router. Plug existing connection and feed from 4g router into it.
Job jobbed.

It should be in the order of months if not years. Home wiring is easy enough to rule out in any case, what's your NTE socket look like?

As I said though, that's how ours are configured. It's backup for an outage, not compensating for a flaky line that we should be fixing.
A home solution could well be different as @oldtennisshoes suggests. On that router can you disable load-balancing and use it as a primary / secondary? Otherwise it's going to be using the 4G permanently which is probably not what you want.
