Getting consistently much lower speeds than I should be ever since my 'upgrades'.
I used to get more or less what my package level said but firstly I was moved to the 100 Mbit service and more recently onto Volt M200 Fibre Broadband.
I still never get anything above 75.
I have tried turning off the hub several times and even tried phoning support - little use that was other than to waste an hour of my time repeating myself over and over to someone who appeared to have no idea what I was talking about.
My hub logs are as follows:

Checked all indoor cables and reseated them. I have no access to the outside cabling as I'm on the 2nd floor.
Restarted the hub and waited 20 minutes and this is what's new:

I still only get 75 Mbit!

Hi @MillmoorRon,
Welcome to our community forums and thank you for your first posts.
Sorry to hear you have been having issues with slow broadband speeds. We can understand this is not ideal and we want to best help.
I have been able to access your service on our system and I can see there are a few hub issues that need a further look into. In this case, I have sent you a private message. Please lookout for the purple envelope and provide a response when you can.
Thanks,

So, can you test speeds directly like this. If you expect >100Mbps then connect a 1GB enabled computer/laptop, with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode ). This ensures that NO other devices are connected
Report back what that gets.
Sorry for the long delay.
Finally got a PC set up near the hub to test this and it does seem to be fine that way.
I have been running for years in modem mode and using my own router and I suspect that it is this which is limiting the throughput.
I have tried putting the hub into router mode (and removing my own from the network) but the hub will not detect any wired devices which are connected through my switches .
Does the hub not work with switches?

Hey MilloorRon, thank you for reaching out and I am glad the connection has improved.
With the switches, please can you attach a picture so we can confirm what switches you mean?
I have also taken a look and the connection is look great from our end. Thanks

The switches are Netgear GS308.
