95% drop in speed

Hello, I am a broadband user at home with the M200 option of 200 Mbps. For about two weeks, the download speed has collapsed, initially to about 40Mbps and now to 10-20Mbps. The upload speed has remained reasonably constant at10-20 Mbps.

I have tried all the DIY tests and checks suggested on the website, multiple times, every day. No change. An ethernet cable does not make any difference. Same speed on my different devices so it is not device-specific. There was no change to the room and router or cable set-up I can think about. I have tried to access the hub via 192.168.0.1 on the browser but it doesn't recognise the WIFI password, which is strange because I know for sure it is the right password I received with the hub.

Please help.

Re: 95% drop in speed

Have you checked the 'Check Service Status' at the top of the page ?

If nothing is showing try phoning 0800 561 0061, this will tell you of more local issues that may be affecting your district. Be aware that it isn't a manned line.

Go round all the accessible internal and external co-ax connections and ensure that they are finger tight.

If everything above is OK we need do some more troubleshooting; to start with …

 

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 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.

Then

 

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then click ‘Check Router Status’.

Copy and paste the contents of the Downstream, Upstream and Network Log tabs onto here, if you get a yellow warning click the Post button again. Use one post for each tab if you wish. Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Re: 95% drop in speed / My BQM graph

Thank you, here's the BQM link

https://www.thinkbroadband.com/broadband/monitoring/quality/share/40034bb31184675733bef3d6b635b16b969ef3fd

 

192.168.0.1 does not recognise my Router password and I don't have access to the info you mention for that reason.

You need to use the settings password ...

Re: 95% drop in speed / My BQM graph

Don't need to go any further with the Hub data.

On your Downstream Channels, several Power Levels are far too low.

You only have one Upstream Channel, we expect to see four.

This will need an engineer to put right.

You can either phone in (08:00 is the best time) or wait on here for a few days (6 to 7 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.
