We have been sent a Sky extender but the signal is very poor. We have 400+ mb in the room with hub but only 25 on average in the room next door and only 2 bars on signal and this is obviously not adequate enough to uninterrupted 4K signal We do have concrete walls but we can pick up next doors EE WiFi signal at full strength !!!!
@Sean184 You may be better to take a look at Powerline then if the wireless wifi cannot get through the walls by the sound of that then that's what is happening!
