Broadband speed dropping

Hello

I'm having issues with my Internet speed dropping. This is causing me major issues when in virtual meetings or in the middle of working online and losing work. 

I have checked the cables, carried out several reboots and run a test on the line. Each time I run a test I get a message saying there is an issue and virgin are aware of it, this has been the same for months with not being sorted. 

Any help would be very much appreciated

Re: Broadband speed dropping

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 …

Disable any VPNs that you have running.

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.

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, Configuration and Network Log tabs onto here, if you get a yellow / straw box 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: Broadband speed dropping

Several of your Downstream Power Levels are too high and several others are knocking on the door.

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'.
