Intermittent loss of WiFi & visual speech not synchronised periodically

[JMJ2]

This morning Sky check acknowledged a week signal so feel a further check on the cable integrity would confirm if we have an intermittent issue. 
Also occasionally we've found the visible speech is not synchronised to the sound.
