Personally I've had about 10 days, although I'm sure it tied in with a Windows Update, even typing this it's SO slow

Use to get 100Mbps all the time, now down 10, 30 tops is around 75

So is it Virgin or Windows !! ??

Maybe it's to do with the massive hack that the world (USA, E.U, Asia etc.) suffered this year

[apcyberax]

a hack wouldn't result in slow speeds. this is a tin foil hat comment.

In my experience Windows update is a very carefully managed process that has little impact on day to day operation.  So a VM problem is more probable.  In terms of "everybody getting slow speeds", nope, my connection has been absolutely fine, and that's got four Windows machines, a Chromebook, and I've been playing around with multiple Linux downloads for another machine, not to mention the new Fire stick downloading a ton of updates, the Chromebook auto-updating, and the older nipper running collaborative degree-level aerospace engineering virtualisations (and gaming and video-calling around that).

Of late we've had a further lockdown, and the start of the 2020 game and console release cycle, both of which have driven traffic up hugely.  So possibly your problems are related to that, rather than your conection?

I'd suggest as a start to see if we can identify a problem, you post your hub's status data for Downstream, Upstream and Network log (as text not screenshots).

Still flucating speeds from 3mbps to 60mbps

No help those logs ?

22/12/2020 06:42:14 critical No Ranging Response received - T3 time-out;VER=3.0;
21/12/2020 18:40:28 Error DHCP RENEW WARNING - Field invalid in response v4 option;CM-VER=3.0;

Is critical and error anything or just a standard ?

The downstream power is much too high. You'll need an engineer visit to correct this, the forum team can arrange this but it takes them a few days to reply. Can a superuser flag this thread to the forum team? 

[jbrennand]

Your downstream power levels are all out of range - all above the maximum (+10dBmV). That will need a tech visit to bring them back into range. call it in asap - although 08.00 is the best time to get through qith no long waita

Thanks for the replies

Yesterday the speeds were great from 11am all above 100Mbps (alas never checked Hub readings as we had managed to get an engineer booked and I presumed he was up the road at the box).

The engineer turned up at 3pm added an attenuator to the hub even though speeds were great he showed me his test phone were some of it was showing red alas can't remember what now.The 100Mpbs lastest for the 8hrs I was logged on too.

This morning the speeds are back flucuating between 33 & 80 Mbps with an Average of 60 Mbps over an hour (20 test readings)

I've called them again and they aren't willing to do anyway as the tests done when on the phone with them were over 55Mbps the min guranteed speed, really strange as we've always had great speeds and I only noticed as I actually thought it was my laptop running slow !

I'm still suspecting dampness in the joint on the pavement as that's where we had our only issue previously in the 3yrs we've had Virgin.

Power is a lot lower down to around 5dBMV
