I thought I had posted this earlier, but obviously not.
Our BB has always been slow (best ever speed in last year has been 1.38MB, currently 0.35, as determined by the SamKnows box we have connected). Slow speeds are something we, in our area, live with as we are between 4=4.5 km from exchange.
However our speed is slow compared to other users in the area (mainly Sky users who seem to get between 2 and 3MB). I had assumed it was a contention issue, BT and TT having gigher contention ratios.
I have just had reason to go into loft to "top-up" the insulation, and in doing so traced the telephone line from where it enters the house to the master socket.
This was installed in the late 1970s, and it looks like the engineer who installed it used it as an excuse to use up all his old BT35a connector boxes and odd lengths of cable, as there are 3 connector boxes in the line.
Just wondering if this could be a contributing factor to our slow speed?
