Just came across this thread by mistake and thought you might benefit from my knowledge as a BT Broadband engineer.
Please check these points if you are having problems with BB.
1) Any installation should have a REN (Ring Equivalent Number) of a maximum of 4. An ordinary phone will have a REN of 1. Other equipment could have a higher value. Don't forget internal or external PC modems. Again these usually have a REN of 1. Each item connected to your telephone wiring will affect the overall REN. The REN is usually stated on a label somewhere on the equipment.
2) Installations with a REN greater than 4 will normally have to have a booster. In the main these are incompatible with BB (since it corrupts the digital signal). Boosters are usually sited near the master socket and make a clicking sound when the phone rings.
3) Make sure every socket that has a phone connected has a filter irrespective of whether or not a PC is connected.
4) BT Master sockets. The face plate can be removed to expose an extension connector and an internal socket (referred to as a Test Socket in this thread). You can add extensions to the internal extension connector which becomes "live" when the face plate is replaced. If you connect a phone or a ADSL filter to the internal socket it is exactly the same as connecting to the socket on the face plate. But if you have extensions connected to the internal extension connector then they are now disconnected for as long as the face plate is removed. This explains why BB works when the ADSL filter is connected to the internal socket.
5) Normally (I did say normally) any old extension cable will suffice for extensions from the Master socket. Extension cables/reels will also work in most circumstances. NOTE: unreeling the cable does not reduce the overall resistance since the cable remains the same length!
6) Distance from exchange is a guide to limit of service. The real measure is signal loss from the exchange. Factors are cable type, cable condition, joint type, joint condition etc. If you are already on the limit for BB then poor internal wiring isn't going to help.
7) If BB works from your master socket then it should work elsewhere in your home subject to the above. A dialtone at the phone does not guarantee a BB signal.
That's all from me for the minute but I will keep an eye on this thread for further questions.

Muttley posted this in response to a long thread about t/p extensions. It has a lot more advice about broadband so I have extracted his reply as a separate post and made it 'sticky'.
Do you know that we're all in line for succession to the throne? Really?

Greyst; Can you make sure there is a "link" to the original thread as it isn't obvious to me how those people in that thread will get the answer to the problems/questions they raised which I believe may be answered by my post?
Cheers

Here's another twist on this problem.
I have set up ADSL on my parents' PC - this is on a working phone installation with 5 extensions. The Broadband MODEM is plugged into the master socket.
The MODEM diagnostics confirm the problem that we see - it sees a broadband signal if we disconnect all of the other extensions (by removing the faceplate that you mention) and, after disconnecting the wiring at all of the other sockets, will work if we add just one extension. When I even just connect open-ended wires to connect towards the next extension, the BB signal instantly drops out. I have tried a simple resistance check across the onward-cabling and there does not seem to be an issue.
Any ideas please ?

Can you please describe your extension network in a little more detail? For example what type of wiring is used i.e. solid/braided conductor, copper or aluminium. What types are the extension sockets. i.e. simple secondary type with connecting post but no other circuitry or master socket with visible electronic components? What is connected to the master socket?
Have you checked all extensions for correct functionality i.e. does each give a dial tone when a phone is connected and ring on an incoming call. Has a filter been attached to each extension?
It is unlikely that the extension wiring takes your connection beyond the BB signaling limit. It is more likely there is a basic wiring fault or inappropriate cables or sockets have been used. Voice traffic isn't fussy about such issues and the human ear/brain filters extraneous noise (like being able to concentrate on one conversation at a party) but BB data is more sensitive.
Lastly, NEVER FORGET YOUR FILTERS!!!

Hi there,
I've been experiencing slow broadband speeds with Tiscali for well over 3 weeks now. The technical support is of no use what so ever! I'm currently on 2mb connection and I'm receiving speeds of 500kbps! Which is madness! I've no spyware, adware or viruses on my machine so nothing is slowing the broadband down...
What the hell could be the problem???? :(
I've also connected a laptop to the broadband to see if it was my pc causing it. That also receives slow speeds... It's nothing to do with the RJ11 cable because when I tested the laptop I plugged the modem into the filter with a two meter cable so it can't be anything to do with the cable being twisted or faulty.
I am very confused....! Can anyone help me...?
I really need 2mb broadband for work purposes
Hope to hear from someone soon..
Many thanks
JJ

Hi. Hoping Muttley is still on here...!!
I recently ordered AOL Broadband silver. The box arrived and set everything up as detailed in the instruction book. Then tried to connect. PROBLEM! The modem could not get the Broadband signal.
On advice of my neighbour, who had had the same problem setting up his broadband, I tried plugging the filter and broadband modem straight into the "Test socket" as you called it, underneath the front panel of the master socket in my house.
This worked perfectly. However, we need to use other phone points around the house, which are obviously disconnected when the front panel is off the master socket.
Therefore, we sent the Broadband kit back and cancelled our subscription, to wait until we had more time to try and find a solution!
Was wondering if you had any ideas?
Thanks

It's really VERY simple, and will be explained in the installation instructions! - you need a filter on EVERY item in the house connected to the telephone - or at least every item has to pass THROUGH a filter! (which is effectively the same thing).
While you had the front cover off the master box, and plugged your filter directly into the master socket underneath, it all worked? - all you needed to do was plug the front of the master socket into the phone socket on that same filter. That means ALL sockets in the house are fed through that single filter, and everything works pefectly.
You then just have to find a way of doing it neatly!, as the test solution I suggested above is rather unsightly!.

I've got the same problem with AOL. I can only connect into the test socket through a filter. When I connect into the face plate of the master socket it will not connect even though I have filters in all of my other sockets. Is it the wiring from the master socket to the other sockets causing this problem???

does it matter that you run a extension from ur main phone socket ? i have mine inthe living room and my pc is in the bed room which means a long cable going around my room ? i would like a telephone socket in my bedroom but i think bt charge quite a lot for this and i,m no good at buying and putting one in my self.

terrible trouble since upgraded my broadband. Everything was fine before. Advice from bt told me that my laptop was sending out more signals than were coming in ,suggesting spyware or something blocking signal and to uninstall them.Anyway bt started working and my yahoo page came on when I clicked on my explorer button.Finalizing Initiation keeps running across the top of the screen.HELP NEEDED.

You should easily be able to run an extension from the master socket, the length of cable should not be an issue.
Ease of installation will depend on the type of master socket. Let me know if you have problems or questions

If it works from the master socket the problems lies somewhere in the extension wiring. Please read my original post but let me know if you still have problems

All broadband services are offered with the understanding that service is subject to a contention ratio. In effect it means your service whether it is 0.5 mb, 1.0 mb or 2.0 mb is "shared" with others.
The normal contention ratio for domestic services is 1:50. So in theory, at the busiest times, your service could be the equivalent of 2.0mb/50= 40k/sec!
In reality you'd be very unlikely to be in that position. Also bear in mind that the site from which you are downloading will itself have capacity limits.

Hi everyone, I've been having an annoying problem with 2 ISP's I joined since last year. I joined Tiscali (BIG mistake) last april, and our contract ended in april 2005 (thank God)
When i was with tiscali, the first 3 months were actually very good, but after that, my 512k Package slowed down to less than 250k, I was getting disconnected EVERY time the phone rang or got used, and when I left their ADSL I was delighted. Now I know spyware and internet threats can be an issue, which is why I keep my PC clean. Since I left tiscali, I moved house and joined Bulldog Broadband, which is also an ADSL connection, only this time I've upgraded to 2mb speed.
I formatted my hard drive to remove any traces of tiscali from my system, and I've got my PC set up the way i want it.And what do you know, same thing, Bulldog is giving me pretty much the same problem, only it's not as often...It's damn annoying.
If anyone could help me with this, you would be doing me a HUGE favour, and for anyone else who is having this problem.
here are my PC specs:
AMD Duron 1800+
ASrock K7S41 Mainboard
Nvidia Ge-force FX5200 128mb AGP display card
2 X 256mb DDR Ram 333mhz
Windows XP Home Edition Service Pack 2
All of my drivers are fully updated etc...
Just to save anyone time if they want to help me, I have contacted Tiscali more than 100 times, no one could help, I have contacted Bulldog via email (no reply and it's been 3 weeks ago now), I rang them up, all I get is "I'm sorry but we're currently experiencing extremely high call volumes".
I did get through in the end but I kept getting told to redial numbers, choose different options, none of which were correct! There was one thing that confused me when I got my modem from bulldog though, they only sent me one filter, which they said was all I needed :-s
If anyone can help me with this problem it would be greatly appreciated, please contact me at: shenmue_rules AT hotmail dot com (for spam purposes I don't use links, just use your noggin' ;-)
Thank you very much for your time
Phil

Actually, the forum works best when all queries and possible solutions are out in the open for all to appreciate (and find via search engines), as opposed to behind closed emails, etc.

Two points regarding RENs and REN boosters:
1) If a phone has a ringer switch (hi, lo, off), would turning it to the 'off' position effectively make the REN of that device zero?
2) Would using a REN booster have the capability of corrupting the firmware in an ADSL router/modem? I appear to have been able to use a system with 8 extensions (plus BB) with a REN booster - but with intermittent problems of losing the ADSL connection (a problem fixed by a firmware upgrade). I'm wondering whether using the REN booster was responsible for corruption the firmware upgrade?
If I can't use my REN booster, I'm hoping I can use a few of my phones with the ringers switched off and have uninterrupted BB.

Maybe a BT engineer will have come across this before?
How on earth can my phone receive incoming calls yet not manage to connect outgoing attempts?
More importantly, how do I fix this?
Phone was fine before I fitted wireless equipment, and if I disconnect the power lead to the router I can call out.
Belkin ADSL Modem with wireless G router located where line enters the house. Belkin wireless and USB network adapter, on the Computer.
Broadband connection appears to be unaffected by phone use. Though I have noticed I'm getting a lot of "connection refused" error messages which stop if I persist trying to connect. Never got them before I wirelessed.
Thanks for any input possible.
