Help with Reduced speed following several faults/disconnects

Go to solution
Hello,
  I’m hoping someone here will be kind enough to help me. I have had BT
Broadband for many years now and rarely had any issues until recently. Following
a number of recent faults my speed has been decreased by about half and I would like
to get it back to how it was. Is it possible to get help with adjusting my noise
margin (or perhaps it’s my IP Profile) please as I am almost certain this is the
issue as to why I cannot get the speeds I did a month ago?
 
The background:
Basically all was well and up until a month ago and I was getting around
12-14MB and now following the faults I am only able to get 6MB (still very
good I know but not what I was able to get for the last couple of years).
 
21st April
Internet went down in the morning, still down the next day, spoke with BT
who arranged an engineer to visit on 23rd April – after a few tests in my home
he visited the exchange and resolved the issue - it seems engineers were working
at the exchange and had accidently mapped my number to another line or something
along those lines according to him.
 
4th May
I found I was unable to make or receive phone calls but internet was mostly
fine (although kept dropping on Friday 6th May), this went on for a couple of
days, BT arranged for an engineer to investigate she visited 6th May and later
confirmed there were some issues in another street that had somehow affected
me(!) and all was now fixed – and indeed it was.
 
Internet has been stable from here on but I have been getting a reduced
speed. I also updated from HomeHub 2.0 to HomeHub 3.0 about 10 days ago and so
that reset a couple of times while the firmware was updated.
 
Having read loads on the forum here I did a quiet line test with a corded
phone (no noise at all that I could hear), tried connecting straight to the master socket,
tested everything my end as best I can and deemed the issue relates to either my
noise margin being set so high or maybe a banded IP Profile after all the
disconnects associated with the above so I thought I should wait out the 3-5
days for it to adjust before posting here. I have been connected for around 7
days solid and saw no change (although last night my hub was reset but still no
change) .
 
 
Hub Settings and Speed test results are below 🙂
 
Thanks a lot,
Graham

BT Test Results
 
1. Best Effort Test:  -provides background information.
Download Speed  5990 Kbps
Max Achievable Speed 7150 Kbps
 
Download speed achieved during the test was - 5990 Kbps
For your connection, the acceptable range of speedsis 2000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :6648 Kbps(DOWN-STREAM), 1131
Kbps(UP-STREAM)
IP Profile for your line is - 5865 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is -
16.67:18.67:64.67 (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.

Re: Help with Reduced speed following several faults/disconnects

Go to solution

with all your disconnections and attempts to try and sort the problem I think you are correct and you are in a banded profile.  However it normally releases after 3 days of stable connection so if you got to 7 days connected (not just hub connected) then it could be stuck.  If you leave hub connected 24/7 with no resets and can post stats showing 3 days connected and still stuck at same speed then you need mod assistance.  Fill out the form http://bt.custhelp.com/app/contact_email/c/4951

Thank you for the quick reply imjolly,
I will wait another three days as you suggest (really don't expect it to change given my experience so far though :)) and will then submit the form.

Kind regards,
Graham

Hello,

 Just wanted to say that Patrick from the mod team contacted me by email and has reset my NR/IP profile today, he suggested it could take 48hrs to resolve but all is already back to how it was before the faults.

 

Huge thanks to imjolly and Patrick Boyle for their quick and polite support in fixing this for me.

 

Very pleased 🙂

Graham
