So new TV arrived yesterday, very nice, very light in weight.
Then found that ethernet connection on the Virgin box is disabled - first idea was to get the wireless dongle that comes as extra with the TV. However was out and about to get a network socket for werk and ended up buying a pair of TP-link powerline adapters and a Logitech wireless keyboard. Got home, plugged everything in and hey presto, it all werks!
Internet connection good over the powerline (500 Mb) and keyboard was recognised by the TV straight away - Mrs Tel may now decide to use the interweb for the first time.
