connecting a skybroadband wireless modem

[J.JJ]

A friend of mine has had a problem with her new wireless internet modem.
When the modem and setup disk arrived she tried in vain to set up her computer on the internet. She spent a great deal: of time on the telephone trying to get technical support to sort out the problem, by setting it up remotely for her.
Each time they told her it was correctly set up, she would put the phone down and her computer would disconnect from the internet.
She was eventually passed to a higher technical person who ran remote tests and told her that although she had a 2MB broadband feed her connection was only capable of 1.2MB.
They also said that she should connect her wireless broadband modem only to a master telephone socket and not a slave telephone socket. They also said that if She had to call in BT she might face a bill of around �120 to sort the problem out if somebody has added sockets around the house etc that have caused this problem ( she is to say the least< a little worried about this situation. ) Needless to say her telephone works fine from this socket.

If anybody can explain why she is having this problem and a possible solution she would be very grateful. I personally would like to know what difference connecting the modem to a slave telephone socket makes, compared to connecting it to a master telephone socket, this is a new one for me.

many thanks in advance of a reply.

It's connection quality.

1) they're right with the master connection. They mean connect straight to the actual socket in the wall, not via a long extension.

2) is she using microfilters? Usually, you connect a microfilter straight into the wall socket. This splits the phone line for phone and internet. this is usually supplied with the modem from your ISP.
