Port Forwarding instructions for the BT Voyager 205 ADSL Router & use Port 6346. Read the instructions carefully & set up a static ip. This is required for port forwarding (opening a port.)

You will also need to force ip on lw: Force IP instructions & sample image

If you do this it will give you consistency for connection.

Also as a last note: A well set-up LW can start to continue its dwnlding after it's settled down perhaps 2 out of 3 times you open LW. Optimising LW & Maximising Uplds & Dwnlds A (1st post only) & also Part B which is even better & last & least are search & dwnld hints.
