BT Sport has always worked fine but we installed a power adapter this week to improve wifi in the house and now find that BT Sport keeps cutting out - black screen, no sound - then comes on a minute or two later. Is the problem likely to be caused by the power adapter? I'm probably being dim about this. Do we need to input the new power adapter wifi code in the same way we did for our laptops etc.?
Any advice much appreciated.
Are you sure it's a wireless connection. The Youview boxes only have a LAN connection rather than wireless. They connect to your directly to the router or as an alternative using HOMEPLUG technology which runs the LAN connection over your electrical wiring. Both of these present a LAN connection to the Youview box. If as you say the hub is only 3 metres from the TV (and I assume Youview box) then the easiest seems to be a LAN cable.
If you are using a HOMEPLUG the recommendation is this is plugged directly into the wall socket and not via 4-way adapter although it does sometimes work.
Never can be wireless or do you mean you have a Wi-Fi extender PLA?
