1GB Upgrade feels pointless: Hub 4 speed issue (ethernet)

[JTN]

Tried the pin reset, tried calling customer services who ran through the same WiFi tests every time even though I'd shared that the speed tests have already been completed and I'm looking at the ethernet issue.

Was told a ticket can't be raised for a technician to visit because they have to send me a cable first. I've checked all the cables, they all work, and are cat6 etc

I'm getting the 1GB hit the router but none fo the devices are getting anywhere near. Most top out around 90-300mbps.

On a iMac (ethernet Cat6) and checked the hardware settings and MTU settings. All seem correct.

Not quite sure what to do next.

Any help would be much appreciated.

You test to see where the speed is being lost.

Assuming your Hub is in the regular Router mode the link below attempts 2 tests

+ first a speed test from the internet to the Hub - this should reflect the subscription rate

+ second a speed test from the hub to the device - the results of this are very dependent on
   the connection method and are often limited by the capabilities of the device especially where WiFi is involved.

Yep, done both of those many times over the last few days.

Current numbers are...

Router gets 1149

Device (ethernet) 189

Do it this way...

Can you test speeds directly like this. 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/ - or https://www.speedtest.net/ - try on 2 different browsers - as Chrome sometimes gives odd results.

If they are still low – boot your device into 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

Thanks for the detailed response. Much appreciated.

After testing speeds across MBP and iMac and iPads/iPhones etc with cabled vs wifi I think I found the problem.

Even though the spec of the ethernet cables are rated cat6 1GB, it seems one of the cables is throttling at 100mbps.

This was proven by switching the router ethernet out from the switch box for a direct link to each machine. All speeds dropped instantly.

Now getting the expected speeds.

Can anyone suggest a good brand of ethernet cable for 1GB please? need to run from downstairs to an upstairs room (approx 25M).

Cheers for all the help so far.

Yes that will be it .... see Tudors response in message 7 here...

You probably just got unlucky or it was damaged when plugging in and out.

I have had good success with Amazon Basics Cat 6 cables for short patching.  For long runs I make my own cables.  Try and avoid "CCA" cables, as these are Copper Coated Aluminium.  Look for a solid copper cored ones, and not the flat cables either.

I've also used Kenable and Rhinocables in the past.  Anything over Cat 6a will be a waste of money btw.

Great stuff, thanks.

That will definitely help avoid buying the wrong cable.

All brilliant advice and appreciate you sharing the money saving tip.

I'm on it! Fingers crossed.
