My connection keeps shutting down

[DDC]

Hi all, this is my first post...

I have Limewire Pro on a G5 running OSX panther 10.3.9. I have an ADSL connection of 512 (in Limewire prefernces i have chosen 'Cable/DSL').

I have big trouble downloading: 95% of my attempts to download a file last only a few minutes on Turbo speed, then quickly my speed decreases until i get the message that there is no connection. It seems that my connection has completely shut down (although on rare occasions it last longer).
However, my desktop says that the connection is still working (the duration time is still moving), but safari can't connect and i cant close the connection! All i can do is restart the computer. i find i'm restarting every 5 minutes while trying to download with Limewire.

This was happening on Limewire Basic, but has become worse since upgrading to Lime-Pro a few days ago.

My download speed is usually around 20KB/s and never above 55 KB/s!!!

If i download more than one file, or do a search while dowloading it my connection crashes.

BTW, I have tried changing to other skins, as suggested in other threads, but i still have the same problem.

Please help...
