I think you have two separate problems.
Did you have a thunderstorm a couple of days ago, or other cause of a lot of instability? The reason I ask is because your downstream noise margin is very high.
I would have suggested you reboot the router, but it looks as though you may have done that this afternoon. I'm wondering if the noise margin has been hiked up by instability. That is costing you at least 1Mbps connection speed.
The second and more immediate problem I suggest is people at work watching Andy Murray. Even my IDNet latency is suffering a little.
