1gig dropping below 300 at times

[Stevehel]

Hi. Recently upgraded to hub 5 and over the last week the Ethernet sports are all over the place but mostly well below 1gig, being around 300. This is connected directly from the router via a Cat 7 cable into my PC. I’m testing using the recommended SamKnows real test and the router itself is always hitting over the amount, but the device as mentioned is not. I’ve reset my router, tried two different cables but to no avail. I’ve also double checked via device manager, Ethernet  that I am on the right speed 1.0. My wireless speeds are better than my Ethernet. 

Any help much appreciated.

try this...

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 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

As soon as I put it in safe mode with networking im getting speeds in the 900’s consistently. Any ideas what could be causing this in windows 11? The pc itself is only used for gaming and is brand new with a fresh install of windows. All drivers are up to date and I only use Microsoft defender with no third party anti virus. 

It’s great that it isn’t a problem with Virgin Media but I’m even more confused as to what could be causing this now.

Thanks for your recommendations, and fast response.

whats make is the Ethernet? maybe you can try new drivers or disable EEE Energy Efficient Ethernet

[Stevehel]

I’ve tried that. As soon as I open a programme called Hardware Info 64 my speed test drops. Now I don’t know if it’s interfering with the result itself and I am getting in the 900 range, or it’s actually affecting my speeds.

If it's working fine in Safe Mode you will have to disable all startup programs and then enable them one at a time to find the culprit.

At least you know VM are not at fault.

What make is the NIC on the PC?  Is it built into the Motherboard?  It may be a better NIC is needed to keep up with the 1Gb speeds? A 2.5Gb NIC connected to the Hub 5's 2.5Gb port would give the best results btw.

[Stevehel]

It’s built into the motherboard but it is a high end Z790 Rog Maximus Hero with 2.5gb. I’m sure it’s HWInfo 64 that’s the culprit. It’s very useful software however. I can’t find anywhere with similar issues. I will try and roll back to a previous version to see if that helps.

Thanks.

Try the Intel(R) I226 Gigabit Ethernet Driver V1.1.3.28

I’ve uninstalled and installed from the Asus site as recommended, and I’m now getting solid speeds. 

Thanks for your help. All sorted now.

Hi @Stevehel 

It's good to see it's all working properly now,

As an aside have you tried the portable version of /hwinfo ?

It may be more up to date than your current version, and if running it from a portable drive/pen drive should ensure it won't affect the speed of your PC if not in use.
