I have been having problems with my Broadband connection with (Surprise,surprise!) TalkTalk.
In January I was getting a, for them, breakneck download speed of 1.96Mbps.
Since then my IP address keeps being changed and almost every time the download speed has dropped.
Today it had got to 1.0Mbps and I finally decided to call their Customer Service to report the fault. A very brave thing to do!
To cut a long story short they informed me that my line could only handle a speed of 1.2Mbps and, since 1.0Mbps was only 20% less than that speed there is no fault. When they then asked me to hold on, I said I would as long as the fault was going to be fixed.
At that the line went dead and my blood pressure rose!
I have tried to discover why my IP addres keeps changing and why this should affect the download speeds but "answer came there none".
As far as I can discover all Broadband suppliers have an Overseas Call Centre where all queries are responded to by using a checklist of questions without any knowlege of IT.
Any easy answer would be welcome but I do find that a lot of your Forum responders talk in a technical language which I do not understand.
