Re: Frequent Packet Drops/Loss - SYNC Timing Syncronisation Failure?

I've been having issues with my Virgin Media fibre connection. At first, all I noticed was that occasionally during Microsoft Teams/Zoom calls whilst working from home, I would occasionally "drop" connection - though I could still see and hear other participants, my feed would freeze for them. 

Initially I shrugged this off as a quirk of those programs, as I was still receiving video streams. However, when gaming I noticed that I would get frequent (but irregular) packetburst and packetloss. This was intrusive, but also in some games causes autodisconnects even though the packetburst lasts for only a brief moment. As such this has made any sort of online gaming practically impossible. At the end of January I set up a Broadband Quality Monitor, and it shows these packetbursts very clearly.

The fact that they also happen in the small hours of the morning, although less frequently, indicates that this is likely an issue with the ISP rather than due to anything on my end as there is no usage during those times.

 I've checked through all the standard checklists, checked physical cable connections, rebooted the router etc. but to no avail. Virgin seems to have a brick wall when trying to contact them to address this however.
