Nothing changed at all, was watching iplayer (in hd without issue) and the connection dropped. It came back up at 512Kbps so I then changed the router in case to rule that out. After many reboots the router(s) are now syncing consistently at 6Mbps. I will try replacing the filter tonight.
I have enabled the broadband quality monitor to see if that sheds any light on the issue:
Any other suggestions?
