Gnutella Forums - Sleepless Nights- Need Help Please!

I tried to follow the exact instructions given on the forum.
From portforwarding to the Windows Firewall to the Norton Configuration.
LW seems to be connected but, it's very, very slow.
It's stated here that the download speed is 2kB/s @ 2KB/s.
I tried doing the port forwarding thingy, however, my task wasn't complete.
Because everytime I tried doing so, the internet connection will be cut off.
I tried calling my Isp, but he told me to get my dns from myself(run->cmd->ipconfig/all->dns servers. It didn't help at all.
Internet connection wasnt resumed, and I was stuck.

This is starting to take a toll.
I tried to configure everything myself, but it's hopeless.
Shareaza doesn't work. Utorrent doesn't work. Bitcomet doesn't work.
