erratic broadband speed

Go to solution

Hi folks

 

A new poster on this forum here.  I've been having issues with my broadband speed for the last three weeks.  I started getting regular disconnections and the home hub 2.0 would show the red light and I would reset it which would get me back online for while before it went down again a few times.  So, I phoned India and was told (after having done the btspeedtester check etc.) that there seemed to be a fault at the exchange.  I was told an engineer would sort out the problem and that would be that.  So it showed I had an open fault on my BT page and that they would phone me back to check how things were.  They did phone while I was at work (and left a message saying they would get back to me that night...they didn't).  Anyway, I did a speed test and things seemed to be back to normal but no sooner had I closed the problem as 'fixed' on the website I started to have erratic broadband speed again.  No disconnections though.  Another phone call to India who promised to sort out the problem and phone me back the next night (they didn't...again).

 

I had been getting a download speed of about 10mb up to three weeks ago but since my second phone call to the call centre it's now about 9 - 9.23mb.  About an hour ago it was down to 2-3mb but has gone back up again to just over 9mb.  This seems to happen quite frequently now.  Would this be down to congestion at the exchange?  Also, does it look like my noise margin is a bit high?  I have tried the quiet line test and it seems fine.

 

I've tried to use the BT speedtester tonight but it's showing an error when trying show the results but my home hub stats are:

I'm using a wired connection at this moment in an ordinary socket (not the master socket) which has always been fine until recently.  I've only ever had a problem with my connection once before about two years ago and it was an exchange issue that was sorted very promptly.

 

It's been strange to have this problem with my connection only recently when previously I could say it was rock solid (pretty much anyway).  I guess I'm looking for some ideas from you guys on here.  I've already learnt quite a lot from reading this forum recently!

 

Thanks in advance.

 

Andy

Re: erratic broadband speed

Go to solution

you still have a 10mb connection speed and as you are on adsl2+ i expect your profile to be correct at 88.2% so could be your download speed.  so can you run btspeedtester not beta and post the results,

 

it would also help if you connected to the test socket as should an engineer be required he will connect to the test socket as this will eliminate all your internal wiring.

 

have yo disconnected the orange bellwire from terminal 3 in all your sockets 

bellwire removal

Hi Welcome to the forums

Here are some help pages done by CL Keith http://www.btinternet.com/~cbeddoe/speed/Speed.html

 

Can you also post the full results fromBT Speedtest speedtester.bt.com

Have you tried connecting to the test socket at the rear of the master socket  Test Socket.jpg

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal


This is a customer to customer self help forum the only BT presence here are the forum moderators

...also finally got the BT speedtester to give me a result of sorts:

 


1. Best Effort Test: -provides background information.

Download Speed
0 Mbps

0 Mbps 21 Mbps
Max Achievable Speed

Download speedachieved during the test was - 0 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 15.2 Mbps

2. Upstream Test: -provides background information.

Upload Speed
0.46 Mbps

0 Mbps 0.83 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 0.46Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps


This test was not conclusive and further testing is required.This might be useful for your Broadband Service Provider to investigate the fault.

 

@imjolly....I live in a rented flat and I'm not sure my landlord would be chuffed with me tampering with his sockets. 🙂

Re: erratic broadband speed

Hi connecting to the test socket has dramatically improved your connection speed which has increased by 7 mb + I would certainly remove any bell wires in any extensions they have no affect on the normal operation of a telephone it only improves your broadband

However you do appear to have a very low download speed could you leave the hub in the test socket and retry the speed test 3 times over the next 24hours to check the speeds out of peak time

If there is any signs of congestion after those tests then we can get you intouch with the forum mods who can investigate further and get the problem resolved

I managed to restart the hub by accident this morning while picking it up so that's why the connection time is low.

Re: erratic broadband speed

your connection speed is far better since you connected to the test socket and suggests there is a problem with your internal wiring.  removing the bellwire will not cause a problem and is permitted by BT - bellwire is a known source of interference on your connection.

 

can you run the btspeedtester beta version and post the results as the main btspeedtester is showing '0' download speed

I've also removed the bellwire from the master socket. 🙂

other wise all looking good now

I'll remove the other bellwires as well and post another speedtest later too...
