Hi there,

My broadband speed has dropped significantly over the past week or so. I was getting around 190mbps, which I was really happy with, but now I'm averaging about 20mbps.

It's infuriating as the drop is actually noticeable and I know that much higher speeds are actually achievable. I don't know what could've changed.

I've followed all of the troubleshooting tips on the website other than trying to connect via an ethernet cables, which I don't have to hand.

The 190 was achieved wireless. I'll try and post the information from the router that I've seen requested in some other posts, but any help from Virgin Media staff would be great (the messaging feature on the app has been less than helpful and I gave up trying to get through via telephone).

Many thanks!

What speeds do you get at >> speedtest.net << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Can you Login to the Hub Settings and navigate to the Connected Devices page - what is the reported 'connection speed’ for the ethernet cable connected device you used for the speed test ?

[MikeRobbo]

Can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Hi Mike,

Thanks for reaching out. I've connected via ethernet and put my hub into modern mode, but now I can't get online and the light on the front of my router is purple.

Any idea what's going on? Should I restart my router?

[Mister_TC]

Managed to restart my hub again and get back online.

In modem mode, with no other devices connected, I get higher speeds, but still not close to 200mbps. Download was 111 mbps and upload was 21.

Connection Speed in Connected Devices is 1000 mbps (!)
