Hello Ronald and welcome,
If you are referring to a TalkTalk VDSL service with a new Openreach modem, then that speed is one of the poorer ones I have ever met.
I assume you mean you are connecting an ethernet cable from the router direct into your laptop in order to do a speed test ?
Can you tell us some more information.
What is the approximate distance to the PCP green cabinet ?
Is the line noisy after you have dialled e.g. just one figure ?
What is the installation configuration starting from the master socket.
Kind regards,
Walter
