SH3 500mb - 100mb down / 37mb up

Hello all,

I recently upgarded my grandparents internet to 500mb. While the speeds did increase it was only from 50mb down (on 350mb connection) to 100mb down (on the new 500mb connection). I believe there is an issue somewhere so thought I would post the data here in hopes of some advice before calling technical support.

Thanks in advance,

Ant.

Re: SH3 500mb - 100mb down / 37mb up

What speeds do you get at >>  SamKnows << 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 ?

Then immediately after …

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 ?

Re: SH3 500mb - 100mb down / 37mb up

Your Downstream Power Levels individually are all within spec but, the differential between the lowest at -4.7dBmV and the highest at -1.0dBmV is too great.

This will need an engineer to put right.

You can either call in (08:00 is the best time) or wait on here for a few days (6 to 10 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'.

Re: SH3 500mb - 100mb down / 37mb up

In the meantime, if possible 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.

Please post a 'Live Link' to your BQM on here straight away.

Instructions for posting BQM Live 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.
