HOW TO TEST WHY YOU CAN ONLY DOWNLOAD FROM ONE USER?
  1. Drop any firewalls, exit completely
  2. Close Peer Guardian and alike
  3. Leave ONLY your Anti-Virus running
  4. Do a port change again in K-Lite. Go to 65000 for now and see if it helps. It does incredible things for me
  5. Do not block bad IP ranges- this is temporary, for testing purposes
  6. Change max uploads to 3
  7. Change downloads to 6, increase this slowly if you get results
  8. No extra idle bandwidth
  9. Turn off Auto Search
  10. Now do a search for shania twain- yeah whatever, but there are a million sources!
  11. Let the search run for at least 2 minutes
  12. Stop the search and select a variety of those results with medium bandwidth and bitrate. about 20 different files for now, both video and audio
  13. Open a command prompt with NetScan Pro 3.3 installed
  14. Enable logging in NetScan Pro 3.3
  15. Close and reopen NetScan
  16. Now view logs if there are any active connections showing.
  17. Get any remote IP's and in the command prompt, type netstat -s 5 to show statistics. do a copy save for future refference
  18. If you're familiar with ping, use the command prompt. If not, get a copy of PCS Network Tools by O'Reilly and enter the IP's shown in the NetScan Pro logs. try the ping 3 times for each one and record results
  19. If you have NeoTrace, do a trace route on each IP that connects. record the hops info and ping times, packet loss
  20. If you still aren't getting connections, It's time to go into the dats for IP info and follow the ping and traces above
  21. If none of this helps "get" sources, at least you'll have the stats needed to properly analyze what's happening and we can go from there.
