Slow ethernet speeds

[willhub]

Hi, I have a peculiar issue that still presents even after factory resetting the hub 

I've tried two different devices via ethernet cable to eliminate a device being the problem.

My phone gets around 888mbit last speed test on wifi6, however for some reason my desktop and laptop connected via ethernet seems to peak at 670mbit.

This is a gig1 line, it's not a fault of the cables either, the configuration here has always been the same and used to hit around 950mbit on the ethernet.

It's almost like the ethernet is capped?? The gigabit port and the other ports produce the same speeds. 

This is on a Hub 5.

Any ideas what could be going on here?

Cheers.

Can you test speeds directly like this. 

As you expect >100Mbps then.... Connect a 1GB enabled computer/laptop (check network card is set to 1GB) , with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have first put in “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode ).

Or - go into the Hub settings and turn off/disable the wifi channels and also disconnect all ethernet cables from the Hub, except your one device. This ensures that NO other devices can be 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 (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

After typing safe mode and also when the router was in modem mode, the issues presents itself still, hitting around 660mbit.

I've tried different cables, it's almost as if a standard Lan port is maxing out and I'd have to use the gigabit port to go higher (it's already connected to the 2.5gbit port).

So two devices used, both on Windows 11, and tried in safe mode and modem mode, I've also tried a separate router and speeds are the same on ethernet 

Something weird is going on here

Hi willhub,

Thank you for reaching back out, I was able to locate you on our system with the details we have for you and cannot see any issues, as you have tried all advised by jbrennand, have you tried a 1 minute pin reset on the Router, this will rule out a software issue.

Regards

Paul.

Hi, the router did a full reset and took 20 mins to factory reset, still issue, I get the feeling the router is defenitly on the blink

Sorry to hear this is still a concern for you @willhub 

I have checked the systems at our side and can see that the hub is receiving the full speed. There can be many reasons for the device showing a slow speed, QoS software, anti-virus, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests to name a some that @jbrennand has mentioned. 

The community is a great space to find and test any 3rd party issues you may have with devices to try and locate/pin point the issue. We recommend using the links and tips kindly provided by @jbrennand to see if these tests and check help your device in achieving the available speeds in the router.

or bad ethernet ports and wifi on the hub...just saying😬

Hi, the reasons for slow speed you given for slow speeds have all been eliminated as per previous comments. 

Two different devices are unlike to suffer from the same problems also. 

And after a factory reset of the hub 5 there is no other reasons I can find clearly must be a hub issue.

Thank you for that information. As you feel that is the case we can take a look into this. 

I will private message you now to confirm your details.
