Poor internet performance in SE London

As the subject says, my internet performance is dreadful. I'm paying for 100Mb/s, and getting on average closer to about 60.

A week ago I decided to look into the issue, as it's making it difficult to work (and things like Spotify streaming sometimes jitter). I connected a computer via ethernet and wrote a Python script to test my internet speed once every hour using speedtest.net. You can see the results of this below.

I've calculated the min, average and the max speed test day (shown in blue, the range representing the min and max, and the average is the solid line). On some days my speed drops below 20Mbit/s, and never actually reaches the speed that I'm paying for. 

I used the reset pin on the router to reset my Hub (I have a Hub 3). No difference, speeds are the same as before.

Re: Poor internet performance in SE London

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 the area. 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: Poor internet performance in SE London

I had a bit of trouble getting the BQM graph working at first - fixed it at 5pm today. The dropped packets before then are just my router blocking pings.

Re: Poor internet performance in SE London

Hi erlend,

 

Thank you for your post and welcome to the community. 

 

I'm very sorry to hear about the broadband issue you're having. 

 

Sadly I am unable to see any details concerning your account from your profile. 

 

Are you continuing to have issues since your post?

Re: Poor internet performance in SE London

It has improved a little bit since I posted. The attached graph shows my daily internet download speed. The solid blue line is the daily average and the shaded region shows the min/max speeds achieved that day. You can see that for the last few days the min daily speed has stayed above 50 Mb/s. My connection does still drop completely sometimes - not as often as it was doing a couple of weeks ago.

I do feel like it should be a bit more reliable than this though.
