Slow Download Internet Speed that geetting Worse and Well below Guaranteed

I have Superhub 4 and on M350.

I get now around 59 to 70 Mbs, and that is testing with the laptop connected directly to the Superhub 4 over cat 6 cable.  The upload is fine and to be honest, is usually just about the 35Mbps at around 36Mbps.  I run the tests at various times of the day and certainly not getting anything close to Guaranteed 181 Mbps.

Here details from my Superhub4

Re: Slow Download Internet Speed that geetting Worse and Well below Guaranteed

Please post the data from the the 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 shots.

A Guru will be along soon to decipher the info.

Re: Slow Download Internet Speed that geetting Worse and Well below Guaranteed

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.

Re: Slow Download Internet Speed that geetting Worse and Well below Guaranteed

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: Slow Download Internet Speed that geetting Worse and Well below Guaranteed

Your Upstream Power Levels are all too high.

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: Slow Download Internet Speed that geetting Worse and Well below Guaranteed

Thanks for the update, what should the upstream power levels be?

Ideally around 45dBmV but anything above 40 up to around 48 is good.
