Slow speed on M100

[tinatulip78]

Hi,

I am having slow download speeds. I have tested my connection on speedtest.net and that is also showing that I am receiving only half of my download speed. I am on a wired connection. Please help!

Nothing really jumps out of the stats!

The only thing that slightly concerns me is the strange power level spread for the downstream channels..

Hopefully someone like Andrew-G, Jbrennand or any other VIP who know a shed-load more than me will be along shortly to advise!

Iotharmat is right - stats all look ok.

First thing you should do is change the ethernet cable to a new Cat5e or Cat6 one - old ones do fail and then test speeds again like this....

_________________________________
Connect your 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.

If they are still low – boot you 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, 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.

Have changed the cable with the new one that came with the hub, no change, same issue.

Have also tried a speedtest via wireless standing right next to the hub, same results.

I'll try the other suggestions and post back.

Thanks
