I have a Three 4G router I use specifically for a couple of rooms that were getting poor reception. Netflix picks up that router in those rooms and the main router in the rest of the house.
I assume they have different IP addresses but no problems from Netflix (yet).
Youfibre does their own mesh system as an add on for £7 a month - that gives you two nodes which will basically rebroadcast the signal from where you put them, so put them somewhere between the router an md the black spot
Another option is for full strength broadcasts is to run a wire between the router and one of the mesh nodes
You can buy the nodes yourself if you don't want a sub
Introducing Amazon eero 6 dual-band mesh Wi-Fi 6 extender | Expands existing eero network https://amzn.eu/d/8Z4aaBD
Or you can buy all router and nodes if don't want to use youfibre but depends on your use case and if currently using extenders I'd say not to bother and just get youmesh from youfibre
I'd flog them, or try take them back and say not working. you absolutely want a mesh network. Extenders are devices of the past and although they can serve a purpose; they often cause a lot of problems.I have only just bought my extenders a month or two back
These are what I have.
I have a deco too. No problems for a few yearsMissed that
The point still stands with Virgin for others though.
Sounds as though the most recent hardware is better but the problems have been around for years.
I personally would buy a mesh system for £100 rather than rent one for £84 per year.
I am vouch for the Tp link Deco devices but have had mine 2/3 years so could be better out there
