Hello.

My download speed has recently slowed down - currently testing at around 90Mbps down, 25Mbps up (e.g. ThinkBroadband ) - I think that's less than the "Minimum Guaranteed Download Speed".  Here's the Broadband Quality Monitor report - there's a spike of packet loss when I disconnected and reconnected everything: BQM

The connection is normally reliable and fast - when I tested in November, I was seeing about 280Mbps down, 25Mbps up.  The values for Power, SNR, and Errors all seem fairly static, at least over about 10 minutes.

Could you do a test with this link : https://www.samknows.com/realspeed/  ( share the results )

For Hubs(3/4/5) in Router mode it tests the service to the Hub and then tests the performance of the computer / device.

Once the test starts click on : Run full test    - to include the Upstream figures.

The speed to the Hub should reflect the subscription rate - if not check for a local faults on 0800 561 0061 ( it is automated )

[jpennycook]

I get this, probably because my Hub is not in router mode:-

RealSpeed is not available on this network

There were no local faults when I checked on the Virgin Media website.

[Client62]

Modem mode & no faults OK.

The 90/25 speed test is typical of a network cabled connection that is at 100Mb/s.

Perhaps look at your computer's network connection to see if it is at 100 / 1000 Mb/s. 

Also does your Router have any connection info screens to show the current Router to Hub data rate.

Ports that drop from 1000 to 100 are often triggered by loose or defective network cables.

[jpennycook]

I checked the cables - no problem there. However, I rebooted everything except the cable modem - speeds are back to normal.

So it looks like it wasn't a Virgin Media problem after all.

Thank you for updating the thread Jpennycook, I am glad all is looking good since your post.

Please let us know if anything changes.
