Thanks for the advice Lord of The Rings.
I had already configured most of the settings that you recommended, but fine tuned a few more. It does not seem to have cured the problem.
It is indeed a strange one, things have improved a tad over the last two or three hours but this was before I did more fine tuning.
At the moment I have three green lights on the speed indicator.
The strange thing is, I am now able to download at full strength even though the speed indicator is showing only three greens.
When I first logged on to LW this morning I only had one green light and I could not search as I did not have a strong enough signal to search and I had a message pop up telling me that I was not connected, yet when I checked the monitor on LW I was uploading to five different users at 28kb's.
I have just checked LW again and I now have four greens, strange.
