Here's a quick guide to the most common reason why your new broadband service won't connect. I've kept it very basic.
As you may already know, broadband (adsl) is simply a wider bandwidth applied to your existing phone line. The standard phone line is known as narrow band.
If you are having trouble connecting to your service, or you can connect but it drops out continuously, check the following first before you contact anyone.
To function properly, broadband does not like anything to get in it's way. Basically, the socket you plug your broadband modem into, must be the first socket the incomming line reaches. This is especially essential if you live any real distance from the suppying telephone exchange.
Most people have the first socket (also known as the master socket) either in their hallway or lounge. They may then have extension sockets around the house which all run from this master socket. So if you have postioned your computer and modem in a bedroom or office room, the chances are you have plugged into an extension socket. This will not work. You may be able to connect for a while, but it will drop out.
The way to solve the problem is to make the socket your modem is plugged into, the master socket. BUT, the phone company own the master socket, so in theory and by Ofcom law, it should not be touched, and you will need a qualified engineer to move it.
If you are experiencing these problems, go and have a look now. See exactly which socket is your master socket. 9 out of 10 people are plugging their modem into an extension socket, then wondering why they are having problems.
I am a BT trained and accredited engineer. I work on phone lines, broadband lines, isdn lines, phone systems, etc, etc. I've been doing this job for 13 years. I visit people daily who are having the above problems with their broadband. I simply move the master socket to where their computer/modem is located, and the problem is solved.
The above is aimed at people who have just had their existing telephone line converted to broad band. If you already have broad band on your line and it has functioned ok but now won't connect or drops out a lot, there are a number of reasons for this.
1. Your service provider has increased your band width...maybe without your prior knowledge..ie: you could connect ok with one meg, and now have problems since being upgraded to 2 meg or adsl max. It is best to get them to decrease to one meg again and this should cure it.
2. There are errors occuring on your data feeds. These are not detectable using online speed checkers etc, but will destroy your broad band connection. The only way to establish whether your connection is erroring is to report your problem to your service provider who will then arrange an engineer to visit with an advanced adsl tester, and hopefully fix the problem.
3. You have recently had new phone extensions fitted in your house/business. Qualified engineers will know the best way to run a new extension for a line supporting broad band. Electricians or people you find in your local paper usually will not. If this has happened to you, get someone qualified to check it over.
4. There is a fault on your telephone line which the automatic line tester will not pick up on. The line tested used by BT and others will only find the obvious faults which will cause serious problems to a phone line. They will not find more minor faults which won't usually effect your speech line too much but will cause havoc with your broad band. This will again require an engineers visit to repair the line.
There are a number of other things which effect broad band such as electro magnetic fields around the cable caused by earthing problems on the mains electric, farmers using electric fences on your cable route, the number of people using broadband in a certain size cable...the list goes on and on.
I hope you find this useful, as the telephone companies/service providers will not tell you this. They will simply bill you for a visit, then inform you after of the problem and the cure. Then bill you again for fixing it.
