for a couple of months, I have been getting slow download speeds 100mbps - 150mbps (not what I pay for) but for the last day I have been getting consistent disconnects from the internet. I have done the standard troubleshooting steps (restart the modem, restart the router, and put the Virgin Hub 3 back in router mode) this has not made any difference. Please see below the logs from my modem.

Please help as I have to work from home and this is becoming a real issue.
Please can you post the other downstream and upstream tables - the ones with the error counts on / timeouts!
Thank you for your reply, please see the requested tables below.

Stats look absolutely fine!!
Yet the log (RCS Partial Service = Downstream trouble) tells a different story!
I'd hang tight for VM Staff to take a look from their end!
In the meantime:
can you set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Oh lordy - that's awful! Hopefully VM staff will see this and respond soon!
Update: I have just lost connection again and can now see the below on the network log, I am currently getting 30-60mbps download.
