Advice on improving my sync please (if at all)

mk1 · Feb 13, 2011, 20:56:33

An update just had a little look, to my surprise only two wires are connected there are further wires but they are not connected, there is no connection for them, i had noticed the extention wire had more than 2 &5 so i removed the remaining wires. After Reconnecting all interesting noise margin is now at this:

ADSL Link      Downstream      Upstream
Connection Speed      3023 kbps 770 kbps
Line Attenuation 57.5 db      31.5 db
Noise Margin      8.9 db      3.4 db

Not sure if i need to wait for this to settle a little?

Just a few days. Amazing what wires can do to your signal, eh.

It's now being reprofiled/banded download sync allready at 4700 I hope that sticks

So you moved from 3023 kbps 10.5 dB to 3023kbps 8.9 dB
That is, your noise got worse by 1.6 dB

If you're lucky, this is just coincidence and has nothing to do with removing the wires. A worsening of noise by 1.6 dB in the space of a few minutes is not unusual.

What's the downstream margin now?

mk1 · Feb 14, 2011, 20:30:48

ADSL Link     Downstream   Upstream
Connection Speed     4712 kbps   826 kbps
Line Attenuation     57.5 db     31.4 db
Noise Margin     3.9 db 4.9 db

Well the sync has gone up!

Looking good! You need to update your "my best ever connection" image

Umm well so far my sync has gone up but no improvement in thoughput?? Also i seem to be getting packetloss alot more at the moment?

I think you've seen the possible cause of this. Check later tomorrow.

Is it going to be fixed tomorrow or something???

Rik · Feb 15, 2011, 18:56:02

A core router is being re-booted at 6am tomorrow, which is expected to cure the problem.

mk1 · Feb 16, 2011, 18:44:45

So problem fixed i gather? Not seen much improvement in throughput speed is still lower than before around 2mb even though sync is at 4.7mb?

What does the BT tester give as your profile?

mk1 · Feb 16, 2011, 19:35:28

Test1 comprises of two tests

1. Best Effort Test: -provides background information.

   Download Speed
   2176 Kbps

0 Kbps   4000 Kbps
Max Achievable Speed

Download speedachieved during the test was - 2176 Kbps
For your connection, the acceptable range of speedsis 1200-4000 Kbps.
Additional Information:
Your DSL Connection Rate :4712 Kbps(DOWN-STREAM), 824 Kbps(UP-STREAM)
IP Profile for your line is - 2500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 9.42:24.65:65.95 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

2. Upstream Test: -provides background information.

   Upload Speed
   686 Kbps

0 Kbps   824 Kbps
Max Achievable Speed

>Upload speed achieved during the test was - 686 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 824 Kbps

Not sure what this really means? Should i not be getting 4mb thoughput?

Lance · Feb 16, 2011, 23:07:56

No, your profile of 2500 is limiting you. This will increse to be in line with that expected for your sync over the next five days.

Rik · Feb 17, 2011, 00:24:16

Assuming that your line maintains a stable connection.

mk1 · Feb 17, 2011, 07:50:27

Well....

My thoughput has gone up last night!
