Just want to pick a few brains here to see if this can be explained.
I am on a fibre connection 1.3 miles from the cab. On the 17th June I noticed my online gaming lagging and decided to have a look at the quality monitor that runs.
Quality Monitor
I felt this was strange and since then and to date has remained at the higher level.
I have a few stats from the BTO modem. The first one was taken 01/12/11

I have rebooted everything a few times and my ip profile has dropped from 18.5 to 14.52Mb but it has not increased back up gradually with me not resetting which makes me think the profile is stuck?
On Wednesday I obtained these stats from the modem

Is there anything obvious in these figures. I am not too sure why the Tx power is showing -128
Any help would be most welcome. The BT checker has my line at 14.3Mb however it has always been over 18Mb since 17a became active on the line last November.
As the line is still above BT's fault threshold there is no complaint to be accepted
