Don't know if this will help but periodicaly I get a very slow connecton. What I do is go round the house and clean all the phone plugs and sockets. This usualy does the trick. Other possibilities if this doesn't work. Disconnect all the phones in the house and see if this improves things. If it does, re-connect the phones one at a time to find out which one is causing the problem. I do know that a faulty handset can cause connectoin speed problems.
