Huge drop in download speed which now wont change

Afternoon all, the service has been fine for the last few weeks but the line rate on the plusnet site is being reported as 1500kbps and downloads are being even slower than that!
In the past we have been at around 6000kbps most of the time, the router has been rebooted a few times over the last few days.
Heres from the bt speedtest site:
Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 5500 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  6048 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 1326 kbps
Cheers for any help.
Rob

I'll go have a look and see if I can spot a problem.
I've had a look and the BRAS profile only updated on BT's system 2 hours ago, and has been picked up on our side now. Can you try rebooting your modem/router and you should see a higher speed come through.

SYNC RATE: 6240

Re: Huge drop in download speed which now wont change

Hello,
I have a similar problem that I email support about before 10am this morning. I still have not had a reply!
Here is a paste job from the ticket I sent....
[Support Wizard Journey]
[Self-test and Raise a Fault]
[Additional Information]
Hello,
I had a connection problem at the beginning of Feb which appears to have returned.
Since Sunday (17th feb) evening I have had a max BT profile of 135kbps. Going on advice I received before, I have waited out the problem but the speed has not increased.
Here are the results from a speedtest taken a few moments ago...

Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 135 kbps
DSL connection rate: 448 kbps(UP-STREAM) 160 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 111 kbps
If you wish to discuss these results please contact your ISP.
If you are experiencing problems with specific applications, servers or websites please contact your ISP for assistance.
Your test has completed please close this window to exit the performance tester.

This is the 2nd time I have had to suffer such a poor connection speed in the last fortnight. What is going on? I signed up to Plus.net as virgin had a terrible xbox LIVE! service that wouldn't even connect. I thought plus' broadband yourway pro would be the answer, but it seems to be as bad as virgin was this month (February). Plus' speed and connection was great in January and I was very happy I made the switch....but to be honest, I don't think I've received £19.99 worth of 'pro' package this month Sad I hope things can return to January's quality soon, I was very satisfied with that.
Here are details from the router's dsl connection analysis:
DSL Status: UP
DSL Modulation Mode: GDMT
DSL Path Mode: INTERLEAVED
Downstream Rate: 160 Kbps
Upstream Rate: 448 Kbps
Downstream Margin: 23 db
Upstream Margin: 20 db
Downstream Line Attenuation: 45
Upstream Line Attenuation: 28
Downstream Transmit Power: 0
Upstream Transmit Power: 0
PVC Connection
Encapsulation: RFC 2364 PPPoA
Multiplexing: VC
Qos: UBR
Pcr Rate: 0
Scr Rate: 0
Autodetect: Disable
VPI: 0
VCI: 38
Enable: Yes
PVC Status: Applied

Kind regards,

Chris.


This was added at 1:35pm.....
I restarted the router once and the line stats for the router have returned to normal.
I have completed another bt speed test and the results are:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 135 kbps
DSL connection rate: 448 kbps(UP-STREAM) 2112 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 112 kbps
If you wish to discuss these results please contact your ISP.
If you are experiencing problems with specific applications, servers or websites please contact your ISP for assistance.
Your test has completed please close this window to exit the performance tester.

The current BT speed test results are:
Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 135 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  352 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 114 kbps
If you wish to discuss these results please contact your ISP.

All in all I must say I am dissapointed with February's service so far, that and the lack of response from the support team.  I signed up for BBYW PRO to receive the best speeds I could in my area and have a good connection to xbox live.  I understand that certain things may be beyond plus' control, but replying to a ticket isn't.
I hope this is resolved and back to normal soon... in the mean time, all xbox live plans are off as is a LAN party (of sorts) I had arranged.  Hopefully March will bring a more positive consistant service than February has.
Kind regards,

Stoley.

Re: Huge drop in download speed which now wont change

Hi Stoley,
You need to understand that the problems you are suffering are outside of our control.  Your speed problem is directly linked to your IP Profile which is determined by your synchronisation speed.
I hope that this article I wrote explains things quite well:
link:speed
I would just ask that you try to ensure that you are connecting to your master socket, you have tried using a different filter and that you have tried using a different router if possible.
Speed faults are often caused by interference, causing your connection to drop and reconnect at a different speed.
