I have a strange issue. I recently changed my Virgin package from TV, Phone and 250mbs broadband to just 250mbs broadband. The costs were getting ridiculous and I never used the TiVo box or landline so I was wasting money. The day my contract changed the phone and tv services stopped though broadband speed appeared to stay the same which was fine. Phones and computers and a speed test confirmed this. However when i now try and stream certain content, YoutTube, more4 catch up services on my Linux based Sony tv it continually stalls and buffers. Before the change everything was faultless. I have switched the TV input now to wired on an old powerline adapter and everything plays really well with no buffering. I also have a firestick which plays through wireless faultlessly.
The hub is close to the tv the download speed looks correct on a phone speed test. Sony tv is using the latest software. Hubs been reset and checked online. Only thing I can see is there is some neighbouring chanel overlap from BT hubs. I'm a little baffled why a problem would suddenly affect one system as some of the TV apps are now unwatchable though I do thankfully have the android firestick to fall back on. Any clues?
