Sound and picture stuttering

[Anonymous User]

I usually watch Now tv on a Youview box but the sound has started stuttering and picture distorted?
This has only just started happening...
Also I used to be able to cast to a chromecast but it looks like its going to cast and throws it out at the last minute?
Any suggestions?
Its now making Now TV unusable...
Thanks

Hi @Anonymous User

Have you tried switching off your router for a minute or so then switch the router back on again to see if there is any improvement ?
