Sudden drop in broadband speed

Go to solution

About 3 weeks ago I noticed a sudden drop in the speed of my broadband connection by a factor of around 8, and it has not improved since. Can anyone offer any advice, please?

 

Details:

 

Home hub 2.0

 

Quiet line test - On a corded phone I can hear a faint hissing, but no loud crackling

 

Socket - I have an older style master socket (no test socket). The socket has an extension wired internally, but nothing is plugged into the extension socket.

 

Below are the adsl stats for the hub connected to the master socket through a filter:

 

ADSL line status
Connection information
Line state    Connected
Connection time    2 days, 0:17:18
Downstream    283 Kbps
Upstream    904 Kbps

ADSL settings
VPI/VCI    0/38
Type    PPPoA
Modulation    ITU-T G.992.5
Latency type    Interleaved
Noise margin (Down/Up)    12.8 dB / 5.7 dB
Line attenuation (Down/Up)    16.0 dB / 6.3 dB
Output power (Down/Up)    0.0 dBm / 12.9 dBm
Loss of Framing (Local)    0
Loss of Signal (Local)    0
Loss of Power (Local)    0
FEC Errors (Down/Up)    849638 / 0
CRC Errors (Down/Up)    0 / N/A
HEC Errors (Down/Up)    N/A / 0
Error Seconds (Local)    0
        
Software version 8.1.H.U (Type A) | Access Click to activate accessibility mode | Time and date  13:56:59  07/11/2012

 

And the speed test:

 

 

1. Best Effort Test:  -provides background information.

 Download  Speed
 0.22 Mbps
   
0 Mbps 0.25 Mbps
Max Achievable Speed

 Download speedachieved during the test was - 0.22 Mbps
 For your connection, the acceptable range of speeds is 0.1 Mbps-0.25 Mbps.
 IP Profile for your line is - 0.25 Mbps

2. Upstream Test:  -provides background information.

 Upload Speed
 0.74 Mbps
   
0 Mbps 0.83 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 0.74Mbps
 Additional Information:
 Upstream Rate IP profile on your line is - 0.83 Mbps

there is something restricting your speed and looking at your attenuation your line should be flying

have you tried changing your filter
it is hard to eliminate internal wiring problems as you do not have a test socket
do you have any thing like a sky box or similar connecting to the phone line ?

Thanks for your reply. I don't have anything else on the phone line. The results I posted were with just the hub connected to the master socket.

 

I'll try changing the filter. If the problem is the filter, how soon after changing it would I expect to see an improvement in speed? Would it be almost immediately, or would I have to wait a few days?

If it is a faulty filter then the connection speed rise should be immediate

Ok, thanks. I'll change the filter, and report back.

I've replaced the filter, but there has been no change in speed. Any other suggestions, please?

I would suggest you contact BT faults on 151 and report the noise on the line but do not mention broadband in the call

Could the hub itself be the problem - it is just over 2 years old now? It's just that the noise on the line seems quite faint to me. Is there any way to eliminate the hub as the cause?

Check behind the extension socket to see if the bellwires are attached.

 

You only need connections on terminals 2 and 5, all others, if any, are capable of depleting broadband.

I could also suggest you look behind the master as well, if the wires are there.

 

But it would be unlawful for you to makes any changes, as these wires also need to "go away".    😉

The bellwires are already disconnected, although not by me.
