I bought a new Panasonic ultra hd television this week (TX-55FZ952B). But have not been able to connect it to the internet yet. My elderly BT home hub 3 is upstairs and the TV is in the lounge. I think a new Home Hub would be required, but which one would be suitable.
Have you actually tried to connect the TV to the HH3 via wifi/wired/other method? If you have and not satisfied with the router's performance then perhaps ask BT to send you their latest & greatest router? You may be lucky enough to get it free from BT.
