I know this has been covered in the past, but...
We have FTTP 100M and a BT smart hub2.
The hub is connected to a Netgear GS105E that has outgoing connections to 2 TVs , Sonos and the BT TV box.
The BT box is connected to a 2*2 HDMI switch with the BT box and a DVD in and 2 TVs out to allow "independent" watching on the TVs.
If we watch the BT box it kills the bandwidth to the point that you cant do anything else on the internet.
If the TV is HDMI straight to the BT box the internet is fine, as is the BT TV picture.
Does anyone have any thoughts please?
