Change of latency + dropouts

Hi, on sunday i was moving some stuff around and accidently pulled out the phone line, plugged it back in and reconnected, but kept dropping out.

 

So went on to the hub setting and to take a look and my downstream speed has dropped from 8000 (maxium possible to 3000ish) 

My latency type has also changed from fast to interleaved, how do i go about getting it changed back to fast to see if that will sort it out.

 

P.s I used to have problems but one day it changed from interleaved to fast and it was sorted.

 

Also my noise margin has always been around that so it shouldn't be that

Many thanks.

Re: Change of latency + dropouts

Hi the  disconnectios  have caused the interleaving to be turned on  and  also  caused the noise margin increase to try and stabilise your line could yo work through the following then we can suggggest a course of action 

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


also post your full hub stats details shown in this link http://www.btinternet.com/~cbeddoe/others/adslstats.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

Re: Change of latency + dropouts

Download speedachieved during the test was - 100 Kbps
 For your connection, the acceptable range of speeds is 600 Kbps-7.15 Mbps.
 Additional Information:
 Your DSL Connection Rate :3.84 Mbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 3 Mbps

 

I have just done the quiet line test, couldn't hear anything no crackles etc

Connect into the test socket as above and re post your router stats.

Re: Change of latency + dropouts

I have done as requested, speed has got better, but test socket is an impractical place and i cant leave it plugged in there

Re: Change of latency + dropouts

Your SNR is still high so there's even more room for improvement.

The problem is with your internal wiring or something connected to your internal wiring. Go through a process of elimination by taking everything off the line and reconnecting it. if the speeds are poor again you know it's the wiring. If the speeds stay high, you know it's something that was connected.
