G4, Mac OS 9.1, under firewall.

The problem is: If I use Limeware i can download all i like but the connection drops after a while.

If I use Mactella PPC the connection is very stable but i CAN'T DOWNLOAD anything...

suggestions?

Make sure that your ports in the Prefs are ok to use through your wall. For downloading it's normal TCP/HTTP download like a browser, make sure that all of that works. then try connecting for the download through port 80 if it's changed (thats the norm for http).

good luck.
