Is it normal for bb speed to drop right down if your modem has been off for a month or so?  Will it pick up again?

Not really.
Has your sync rate changed?

Thanks

How do I find that out?

Ive actually changed to a wireless modem but the slow-down was evident before I did that.  Back down to 0.2 Mb/s Feckin so-called broadband...  

Check your microfilters.  Seriously, if youve been off for a month, and the cable unplugged the connection may be gummed.  

Open the main BT box and plug directly into the service socket, this will ensure there is as little as possible between the modem and the line. Try at least two filters.

The main connection is direct into the service socket and all filters in use are new.

21/10/2009 @ 17:26      Deployment of additional broadband capacity
We are pleased to announce that we have added another 155Mbps segment of central bandwidth to our network. Broadband customers connecting to this new segment will access the Internet through the gateway known as thn-ag01.

Weve activated this extra capacity in line with the current budget and our projected growth in customer numbers.

Kind Regards,

21/10/2009 @ 17:06    Broadband Network Capacity (285660) - UPDATE
This is an update to the announcement we made last week about performance problems and speed issues for some customers during peak times when the network is busy.

We are still aware that there are a number of customers are reporting slower than expected speeds during the late afternoon and early evenings, and we would like to apologise to those still experiencing difficulties.

We have experienced a number of problems recently, most notably issues concerning network balance and a problem that affected our traffic management switches last week. These issues have been further compounded and made harder to identify due to the growth in traffic on the network following Microsofts recently released security updates - http://news.bbc.co.uk/2/hi/8302286.stm

We lit another segment of central capacity on Monday, however the benefits of this have been somewhat eclipsed by the fact that a problem on the network yesterday evening resulted in close to 30,000 customers being briefly disconnected from the Internet. This is very unfortunate as it has resulted in further imbalance across our broadband platform which will not be helping the current situation - http://www.plus.net/support/service/problems/problem.php?intProblemId=58763

We have more central bandwidth scheduled to be lit over the coming weeks and were continuing to monitor the network in case weve overlooked anything else that may be contributing to these problems.

Customers on certain account types will continue to see slower speeds than they are used to during peak times, particularly traffic that falls into our download sites/servers classification or traffic that is rate limited during peak hours - http://www.plus.net/support/broadband/quality_broadband/download_servers.shtml
http://www.plus.net/support/broadband/quality_broadband/speed.shtml

Customers on our Broadband Pro product are less likely to notice these problems as all of their Internet traffic is prioritised regardless as to the time of day.

Service Status remains at Amber and the network is still in Plan B operation - http://www.plus.net/support/broadband/quality_broadband/load.shtml

Sorry for the continued inconvenience, and thanks for your patience whilst we work to resolve these issues.

Kind Regards,

Bob Pullen

Thanks but its not that.  My speed is hammered permanently - not just at peak times.

Replied to your PM.

Idea is to limit it to one filter and no other items on the line to eliminate them from the equation. A new filter can be duff on arrival

The line is direct into the box with no filter (as recommended).  I have filters on other kit (as recommended).

48hrs and still nothing from Plusnet...

first time ive ever heard that. 100% sure thats right? not got spurs off before the face plate at all have you?

Matt

Its one of those BT dedicated internet connection thingies.

If its an NTE2000 face plate, you dont need microfilters anywhere else.

[size=24]FINALLY[/size], Ive got someone to look into this and theyve confirmed its a BT line fault as suspected.  Hopefully itll get sorted now.

FFS, what does it take? Customer service isnt rocket science...
