When with AOL my speed was a constant 2 meg or within a whisker. Changed to Entanet and getting 3.2 Meg on average. At weekends it sometimes dives down to about 2. Seem to have more 'dropouts' on my new ISP than AOL. Still I'll see how it goes. However your second link makes me think that may be something is wrong other than your ISP. Try rebooting router, check your filters and try connecting from the master socket if on an extension lead.
Only thing I can think is they upgraded some of the cables as it was old ally cable that was on its way out when I was on dial-Up. I also run a Extension Cable from BT socket near front door to My Old 98se Desktop upstairs over 100 ft long without any problems. I think its that I made my own cable up using multi wire telephone cable Splitting it at the BT box two wire for phone and two for BB so I only use one filter at the BT box
That's interesting. Unfortunately for me I have a BT 'box' on a window frame installed when Moses was a little child. One screw type just like a junction box. Not to be opened only by BT engineers from what I gather. From that there is a normal BT box which I thought of as 'master'. From the second box (master?) there runs an extension to the bedroom box. Confusing myself now. Old BT wiring in the house. No wonder that gizmo, the one that disables the telephone bell wire, was a mystery to me.
