Hi @RussGregory thanks for getting back to me, is it possible to connect the box via ethernet to test if the problem is caused by the adapters?
Are you sure they are wifi adapters as it's not recommended to connect the TV box via wifi? We recommend that you connect the BT TV box via an ethernet cable or ethernet powerline adapters, these use your electrical cabling to carry the broadband signal to your Hub.
Sorry, yes they are BT PLUG in adapters that connect the bt box via plug sockets and Ethernet cables to the router. I unplugged them both and Re plugged in and works fine now. 😀
