My BT Home Hub 5 is located in an upstairs bedroom and provides decent wi-fi coverage to my 3 bed semi including part of the lounge. Running SpeedTest on my laptop in the lounge gives me 63Mbps - the same as a wired connection upstairs. But on the other side of the lounge where I have my Loewe Smart TV, Sky Q and Oppo 203 UHD player the wi-fi signal is severely hampered by the chimney breast. So all those devices are connected via ethernet to homeplugs. Watching YouTube videos on the TV (via ethernet) shows a download rate of around 22Mbps - virtually a third of the wi-fi speed on the other side of the room. Downloading a 4K film from Sky takes several hours and I tend to leave it until I go to bed to start it. I want to use the full capability of my BT Hub but the only way possible seems to be via mesh wi-fi. A satellite in the lounge would greatly increase the speed. The proposed location of this satellite would be on the opposite wall to my TV etc. so it can pick up the signal from the router upstairs. However, there is a fly in the ointment. Whilst the TV, Oppo 203 and Sky Q box have wi-fi capability the Yamaha RX-A3010 AVR doesn't. It's ethernet only. And I have two PCs, a printer and a Synology NAS box in the same bedroom as the existing BT Home Hub 5 all connected via ethernet. The NAS box has my music stored on it which the Oppo needs to 'see' in order to play it gaplessly. I suppose as long as those are connected to the mesh router via Ethernet they will be fine. Is that possible? But the AVR appears to be the sticking point since I can't see any way other than ethernet via a homeplug to connect it to this new 'mesh' network. Is that the only solution but given the AVR isn't going to be downloading anything off the internet is it important? Any advice greatly appreciated.
