Adding 4G as back up to Fibre ISP

[PeterTTT]

I have a pretty good Fibre ISP to my house. (600mbps) that was recently installed and I use a few Linksys Atlas Pro 6 Velop nodes that push the signal out well around my house. The nodes are CAT 6 wired to a network switch so coverage is great.
I also have a Netgear Orbi LBR20 that I used to use as I relied on 4G data sim from EE for my internet previously.
The Fibre connection is very stable but if possible I would liike the 4G to act as a back up if the Fibre goes down. Googling seems to call this a failover solution?
Is there an easy way to add the 4G as a backup if/when the Fibre ISP goes down so I have conituous broadband service?
Thanks
Peter

There certainly is. I can't give you specifics for other providers, but BT, here in our office, do exactly this. We have the fibre modem and another 4g modem. When the fibre one goes off line, the 4g one kicks in. It does take about a minute or so though, it's not instantaneous.
They are connected together , and I guess, communicate with regard to the fibre signal.

TBH I would go down the draytek route with a 4G dongle that will provide backup if the main circuit goes down and it can do basic SDWAN if the 4G carrier requires certain use per month

What you need is a router that can do load balancing with failover. Fibre goes into WAN1 and 4G into WAN2, you can then set the failover if one goes down.

Problem may be your Fibre ISP, will they let you use an alternative router? What router do they provide?

You could consider a tp-link er605 device being fed from the fttp device and from the netgear unit if that operates in modem mode.

You would have to change the velop into access point mode but easily doable.

no need to use an alternative router, just use the router you want to use as a single client to the ISP router. I have a draytek router in this configuration to a starlink router and works perfectly. Sure there's 2 routers running, but no issues so long as you ensure the IP ranges are separated.
