Have you tried their ‘whole home wifi’ access points … these provide a very good mesh service.

They are excellent, but the version for any ISP seems discontinued The rented version for use with BT SmartHub's may still exist, but with ongoing rental??

It was not a slight on the RT-AX88u which is a really good router.

It was whether, (when using very little wifi and mostly using ethernet for almost everything), that an SH2 could cope

I would certainly expect it to cope well enough, given that BT sell a 900M service, and this BT-supplied router is specifically designed to be used with that service (and to keep customers happy).

That was my view and was why I asked for views about using the SH2 in this thread.

As I understand it; the SH2 has a 1Ghz 2 core CPU and thr RT-AX88u has a 1.8 Ghz 4 core CPU so both should have been able to cope with the ethernet and I did not notice any ethernet issues but with 900 Mbps I did not expect that I would. - However, with Wifi, I did notice that Wifi browsing intermittently hung on the SH2 which may have been due to it being busy looking after ethernet but obviously that is subjective.

The Wifi Range of the SH2 was really good but some web pages hung. - (Possibly because the SH2 was busy with ethernet. - I do not know).

Also, the theory that using the SH2 would enable BT to keep a contemporaneous record of BT SpeedTests Carried out via the BT App appears to be junk since BT Customer Services have told me that every new BT App Speed Test overwrite the previous test.

One of the reasons that we asked about the feasibility of just using the SH2 was that we were considering uprating and buying the new RT-AX88u Pro, (virtually not difference to the RT-AX88u with a slightly faster 2 Ghz 4 core CPU), and we did buy one and after we installed the RT-AX88u Pro no issues whatsoever.

We are now using the RT-AX88u in Access Point mode to give better Wifi to the rear garden.

Presently cooking on gas.

As well as worrying about the GHz of a processor you should look at the family. For example a modern intel i5 11th generation at 1.0 GHz vastly outperforms a 3rd Gen i5 and 2.4 GHz. Clock speed is not really a measure of performance anymore.
