@Chrisee 

Thanks. I thought that this would be the case. Its been like this for around six months so I am putting the lack of action down to the pandemic. I have gotten used to the 8pm-11pm slowdown but last night was the first time I have expereinced it starting at 5pm.

I have suffered multiple disconnects in the lat two days and lost 4mb in sync speed. Sync speed was 71213 now its 4m lower. Noise margin was also 3.4  Logs and stats below

[Fatmanp89]

The health check says there was an issue with my hub. It runs another 2 minute test and says thats fine repeat loop.

[Fatmanp89]

Would anybody have any clue why the health check fails at step 2 regarding connection to my equipment? There were no disconnections overnight but have noticed a thoughoutput reduction on speedtest sites this morning.

I often get the warning sign when doing the health check and just like you when you continue and complete the test it reports no issues and claims everything is ok - if you then test again the warning symbol returns.

Slow speeds again tonight btw - dropped down to between 30-40Mbps at the moments down from the usual 72-74Mbps <sigh>

Been over a week since my noise margin increased and sync speed reduced. Connection has been stable at 67mb but it resynced at 66mb with no noise margin drop. The heal check works now. So that's 5mb in 10 days lost.

DLM reset late last week. Just had a random disconnection at about 1pm today and the router resynced at 59mb despite the noise margin sitting at 3.4 so did a reboot and it went back up to 69700 (was 70100). @AndyStubbs any issues your end?

[AndyStubbs]

No issues that I am aware of - sync speed and download speeds have remained fairly consistent.

Absolutely shocking speeds again tonight - half of usual speeds. Anybody else having issues on Catford exchange (or in general)

[AndyStubbs]

Seems to be a nightly event now - after 7pm speeds drop by 50%. Usually at 72Mbps - but after 7pm its down to 30Mbps.
Never used to be this bad - I actually get faster speeds from vodafone 4g.

My internet dropped tonight aswell mate, Completely went off and then my conneciton speed also rapidly dropped 

[AndyStubbs]

Speeds are right down again this evening to roughly 50% of usual download speed.

Connected at a very healthy 

Line Rate - Upstream (Kbps):20000

Line Rate - Downstream (Kbps):80000

Yet download speed is down from its usual 76Mbps to roughly half that (upload remains the same as usual hovering around 18.8Mbps).
I have a feeling something much larger is going on tonight though as I have just tested my Three 5g connection which has also taken a nosedive in the speed department (Usually 250Mbps to 370Mbps but tonight down to under 100Mbps) and also my Vodafone 4G+ connection has taken a significant dive into the floor.
