Hub 4 not working correctly

on ‎12-09-2022 

Hi,

Hub 4 1Gig fibre. Had a week and still not working any where near desired speeds on wired connection at best 50%
Wi-Fi is not great either  around house and nowhere close to speed promised, not even 30% not even whilst standing next to it using different devices ( Samsung flag ship S22 Ultra and an older Samsung S10 show similar bandwidth 330mb/s)
But it's the wired connection that's the main problem.
Followed instructions on website. Wait 2 hrs as service updated.
No change at all.
Called tech support. Went through the motions, have you down powered and reset etc.
Then told to try a new network cable as i  was using a cat 5, new cable issued by VM within 48 hrs, No change at all and to top it all off it was still a cat 5 ethernet cable.
Called service support again and cannot see any faults, so is stating it could be my PC, so was told to try either someone else's pc or equipment like an Xbox etc to connect to it or buy a new cat 6 0r even cat 7 ethernet cable.

I don't believe that any of my equipment is at at fault.

Please help

Virgin "promise" 20mb over wifi, are you getting less than this?

Can you visit https://samknows.com/realspeed/ to see how your wired speeds are so you can find out where the bottleneck is

Buy yourself a good Cat6a ethernet cable and use that to test speeds.

The VM wifi promise (that you qualify for on 1GB) is here...

Hi John,

Thank you for your reply to my query.
I have now ordered myself some cat 7 cables and even going to try a cat 8 to my pc.

I've also used the virgin media connect app which shows my hub speed to be 1133Mbps and my wi-fi speeds to be 433Mbps whilst i'm within 2foot of my Hub 4 router .
It also quotes my device capability to be 867Mbps.
So maybe it is all down to Quality of ethernet cables to my pc.

I shall update with my findings once new cables arrive.

Best regards,
Chris

Thank you for your response to my post.

I have tried the link you suggested and it truly shows there is a concern with my PC not receiving the full bandwidth.

 So I am now investing into some new Quality Ethernet Cat8 and Cat7 cables to connect through and see if that makes the difference.
If not then it may end up being more hardware upgrades in my pc.

I shall keep you informed of any findings / progress.

Best regards,
Chris

The Hub4 is only wifi5. The maximum speed you will receive on a single ordinary device is ~500Mbps. You need wifi6 equipment to guarantee get any higher wifi speeds.

But see this excellent thread with good examples of maximum theoretical wifi speeds on wifi 5 with different “parameters” varying.

To test speeds correctly can you do it this way.
_______________________________________

As 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 as Chrome sometimes gives odd results.

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, anti-virus, 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. For examples of why... see message 7 in the first thread and 9 in in the second and 3 in the third
