When I follow the 'set up wifi' in advanced settings, it accepts the network name and password with no problem, but the wifi speaker does not appear in the controller. If I try and connect via the usual 'Add a Player' menu, then it never gets to the stage of the flashing green light, so it cannot be set up through that route.
I submitted a diagnostic report about 10 minutes ago.

If your router and extenders are not in the same room as each other and you want to achieve a seamless network around the house, it is advisable to set them all to the same channel.
Your Mac is currently joining the 5GHz wifi from the BT Hub; let's get this on the 2.4GHz band instead while we're setting up the system, as this seems to be the same network name (SSID) as your extenders are using.
If the wireless setup fails again, get all the Players in the same room with a at least one wired to the main router and try it like that.
