Slower speed after upgrade

A Virgin engineer visited this morning to upgrade my M350 broadband with no telephony service to M500 Broadband with telephony.  The visit smply involved attaching a small phone adapter to the router.  He advised that the speed upgrade would take anywhere between 5 minutes and 2 hours to become active.

My speed after 4 hours has reduced to little more than 200 where I was getting 320-350.  No sign of a speed increase.  Is it possible that the service reconfiguration has not been implemented properly?

Re: Slower speed after upgrade

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 can 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. 

When the page appears DO NOT LOG IN but 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 warning click the Post button again.

Many thanks for the quick reply.  I think I’ve followed the instructions for the BQM properly

Re: Slower speed after upgrade

No clue why an engineer visit was needed to press a button on a computer and give your account  a new Faster Config file esp 350>500 as it is the same HUB3.

I assume he connected his meter to test the power levels to see if they were within OK levels.

Many like myself on this very forum found we went from a 99.9% of the time stable 350 full speed to not so stable 500 (I had 500 for about 1-2months AFAIR) and same again for me the past week now on 1Gb/s but with a HUB4.

Re: Slower speed after upgrade

Not that I noticed, I’m sure his actions were limited to connecting the telephone dongle into the back of the router.

Re: Slower speed after upgrade

I am not in the correct colour zone (Red/Purple etc) for that yet so no VOIP phone for me so it is the old method not connected to the HUB.
