Murasame is right, however LW loves to be babysitted, this means that you can find more sources by searching for the file you download, LW will pick new sources instantly. I do that everytime my download slows to a crawl.
For the connection problem, be sure to open your firewall (if you have one) at port 6346 and forward that same port on the router setup web page (if you have a router) to your lan address (ie 192.168.1.100).
Bonne chance |
