I installed the stable version of debian, using the minimal CD, the 
instalation recognized properly the network card installed, but at the point 
when was neccesary to get the package sources from internet, there was an 
error, checking /etc/network/interfaces, the network card was configured 
properly.

ping localhost   fine
ping 192.168.0.150  (ip for the debians computer)  fine  mask 255.255.255.0
/****************************

having other computers in the network the router gives answer to all the 
rest.
