BT Fibre and Best Mesh System

[Bobthebyk]

I am new to the forum and not overly savvy on the tech front so would appreciate help. I current have a BT Fibre Smarthub and get a speed of around 300 to 500. Connected to it are BT Premium Discs. There is also a wired link to a garage where I have put in a NetGear WAX 206 Access point. That provides a separate wifi network for the Garage which works well.
The problem that I have is that the BT premium wholehome discs constantly drop connection and are not monitorable from outside the home so I never know what is going on until someone calls me to tell me it is not working (generally my children).
Can people possibly recommend the best Mesh system to replace the BT premium discs and whether I should take out the SmartHub from the system as well or keep it? I need to cover a fairly large area so probably need 3 or 4 nodes I think and want to be able to monitor remotely too. I do not use voice services from BT, only internet and so could ditch the SmartHub.
If the recommendation is to keep the smathub but add a Mesh, I probably need words of one syllable to explain how I should set it up and any settings that need changing.
Thanks

Thanks - this is helpful and I can see a mixture of suggestions including TP Link PX50 and Asus products. What I am struggling with is working out:
(i) which of these work well with BT internet
(ii) do they replace the SmartHub and, if not, is there something that one has to do within the SmartHub to allow them to work; and
(iii) can one access the whole system remotely from any location to check it is working.
Again, apologies if this has already been covered. I am really just looking for a very simple recommendation and noddy guide to what to do.

Thanks Greg - I suspected that the "premium" discs were less than premium! Very helpful advice. On the Eero Pro 6, from memory that only has 2 or 3 ethernet ports and so I would probably need a switch if I need to connect more to the router.
Would you suggest the TPLink PX50 so I can try to use the powerline too. Would that also replace the BT router?
Sorry for so many questions.

Sorry - last question is whether any of these systems will have a problem with the separate Net Gear WAX206 access point in the garage. I want to make sure they do not block each other or have incompatiblity.
