Internet keeps dropping out - SYNC Timing Synchronization failure

Hi,

Been having this intermittent issue for approximately 2 weeks now.  When i say intermittent, its everyday, at intermittent points through the day.  
To confirm:
This is on multiple devices including Android phones, android tablet, 2 laptops on both frequency bands (2.4 & 5ghz), & desktop hard wired ethernet direct to router.

All devices drop at the same time.

I have ensured connections are tight on back of router, and on connection point internally in the house.

I have power cycled the router multiple times.

I have factory reset the router.

I have setup on thinkbroadband the monitoring wherein it pings continously.  See below of results.

Upon visiting the status within my account, where i enter postcode and surname, its had on there listed there is a broadband issue pretty much everyday.

To put it lightly, I'm tiredof this, who do i speak to / what do i do next, as both my wife & I wfh?  The support desk is frustrating, as they just blame your equipment.  I'm technical, so please do let me know if i can try something different, or whether its needing an engineer to come out?
