Slow Broadband Speed

Go to solution

I've had around 7mb download speed since I joined BT but for about a month that has dropped to around 2mb.  I ran the speed test twice over a couple of weeks and got the same results.  HAd an online techie who ran through a series of test and made changes but no solution.  He reckoned it was an internal fault (in my house).  I have a BT accelerator plate fitted so no phone line (or any other) interference and I've tested the connection directly plugged into the main socket.  I don't understand how I was able to get 7mbps before and now (with no changes at my end) I only get 2mbps.  Can anyone help?

 

Stats posted below.

 

Download speed - 1.97mbps

Max Achievable - 2mbps

Acceptable range - 400kbps - 2mbps

DSL connection rate - 8.13mbps downstream / 448mbps upstream

IP profile - 2mbps

 

Hub ADSL Stats:

 

ADSL settings
 
Downstream - 8.128kbps
Upstream - 448kbps
VPI/VCI - 0/38
Type PPPoA
Modulation - ITU-T G.992.1
Latency Type - Fast
Noise Margin (down/up) - 12.1db/22.0db
Attenuation - 10.0db / 5.0db
output power (down/up) - 13.8dbm / 12.3dbm

if your connection time is 3days+ then your profile is stuck at 2000 instead of 7150 and you need to contact the mods for assistance

contact mods



can take up to 3 days for mods to contact you

Re: Slow Broadband Speed

Thanks for you response.  I have read all the pages you suggested and I don't see anything that would explain my problem.  As I said, my hub is connected via a BT accelaerator faceplate at the main (in) socket and I have tried plugging the hub directly into this (without an extension cabling) but still get the same slow speed.  I have tried connecting wireless and ethernet but always the same speed.  As I said I have had a constant 7mbps since I joined BT a year ago and my wiring has not changed nor has the location of the hub but for at least a month I've only been getting up to 2mbps.

 

Here are the results of the further tests I performed today:

 

ADSL settings
 
Downstream - 8.128kbps
Upstream - 448kbps
VPI/VCI - 0/38
Type PPPoA
Modulation - ITU-T G.992.1

Noise Margin (down/up) - 12.1db/22.0db
Attenuation - 10.0db / 5.0db
output power (down/up) - 13.8dbm / 12.3dbm
 
Loss of framing (local) - 0
Loss of signal (local) - 0
Loss of power (local) - 0
FCC errors (down/up) - 0
CRC errors (down/up) - 56 / NA
HCC errors (down/up) - NA / 17
Error seconds (local) - 36
 
Max ADSL Speed Test Calculator results:
Downstream Attenuation - 10 db       Approx line length - 0.7km
DSLmax - 8128kbps                         IP profile - 7150kbps

Thanks for your input.  If you see my reply to Kieth Beddoe's response you'll see the results from tests he asked me to try.  When you say 'connection time 3 days +'  what do you mean?  My hub is on all the time but my laptop is not on / connected all the time.  The stats show my connection time as 1 day 9:18:16, not sure exactly what that means.

your hub must stay connected for 3days + with no restarts for your ip profile to reset automatically if it has not reset by then it will need manual intervention by the forum moderators to release it

Your hub has reset its self recently that is the reason for the 1 day plus time scale

Your IP profile is stuck in a 2000Kb banded profile.

 

This can happen if there has been a fault, or your hub has been restarted or disconnected too many times.

 

As John said, leave it connected for 3 days, then run a BT Speedtest again. If the IP profile is still showing 2000, then contact the BT Care Team as below. But you must leave it for that amount of time first.

 

If you would like to contact one of the UK based BT Care Team who moderate this forum, they should be able to help you.

 

 

 

They can be contacted using this link BT Care Team

 

 

 

They normally respond by phone or e-mail, within three working days.

Re: Slow Broadband Speed

Thanks for all responses.  I'll do as suggested and leave it for another 3 days then run tests again.  I assume I don't have to have my laptop on and connected to the internet as well?

 

I'll keep you posted.

No you don`t, just leave the hub on and plugged into the phone line.

Monday 20 Feb.  Connection up for 3 days and speed is back to 7mbps (approx) as it used to be.  Thanks for all contributions.
