One of my old D-link adapters died, and I was sent a new pair. Cannot get them to work, despite using all new ethernet cables, trying every socket, and resetting everything a million times. Trying to watch a film on Netfix or on catchup TV is impossible, loads very, very slowly, and then after a few minutes it starts buffering. Never had this problem with the old setup. My modem and powerline adapters are all fairly old, but until now have all worked perfectly. Have checked my internet speed and that's OK, and my internet generally works, just now cannot use apps and players on my You View box.
