Great stuff, thank you. I'm about to come to the end of my BB contract with BT and likely to move to Sky so perhaps the timing is helpful. Appreciate your expertise.
Well it was worth a try. There is obviously an issue with the BT Whole Home discs. I am surprised you needed four of them, as overlapping coverage can cause issues with some mesh systems.
I had a Tenda Nova MW3 with three units, and that gave similar issue to what you are getting, and the only way to get my phone to connect, was to turn off the phone Wi-Fi for a short while.
I now use the TP Link Deco M4 with four nodes, and it does not suffer from any issues. It also has the advantage of a separate guest network which can be configured to 2.4GHz only, which suits my 2.4GHz wireless cameras and some other devices. The Deco app is much better than the Tenda one, but you do have to create an account.
I am only on a 12Mb ADSL connection, but its just fine, as there are only the two of us living here.
Hopefully you should find the Deco much better.
It’s a large three storey house but possibly overkill. Thanks again for your input.
It’s a cheap way to resolve the wireless issues of the SH2 router. As explained by other posters in this thread.
Just to get this off my chest, BT second line support have got involved. They reckoned one disc had a poor connection despite the app saying it was good so I moved that, since then the system has crashed numerous times including overnight. I’ve just done the reset on all the discs and it lasted 35 mins before crashing. With BT support taking days to respond I’m totally unimpressed.
