I download speed goes down when doing speed test

[Tomo32]

Basically random parts through the day my discord will start lagging amd then I will be on like 5k ping getting insane amounts of packet loss and when I do a speed test it will start high but go lower and lower and the test is happening

Do a pure speedtest like 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

this happened a year ago at random intervals of the day my internet would get insane packet loss and we had a guy come out and he lowered the internet frequency or somthing

Hi @Tomo32

Thanks for your post and sorry to hear about the issue with your broadband.

I have had a remote check and everything looks fine on our end right now, could you follow the instructions from our very helpful jbrennand please and keep me updated with how you get on?
