Slow speeds

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:

Stats look ok - but can you start from a clean sheet by doing this...
_____________________________________________________
Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check from time to time to see if they start reappearing - they shouldn't.

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's & TP-Link Archer C64 WAP. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

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!

Ok if that is over an ethernet cable, swap it to a new Cat5e/6 one and try again. Ensure the device has up to date drivers and the Network card is set to 1GB and not 100Mbps.

If still slow - test this way
_______________________

If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, you cannot rely on wifi tests, - no BB supplier guarantees those - only speeds "TO" the Hub are guaranteed.
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

Test speeds at https://speedtest.samknows.com/ - try on 2 different browsers.

If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.

There are many posts on here (I have a list of ~30!) where QoS software, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.

Report back what that gets.

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,

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.

Do all the link lights come on when you connect the switch to the hub and a device to the switch? Have you tried different Ethernet cables?
