I am consistantly having a problem where i connect to a wifi network and have full bars 70%-100% signal strength.. I get internet for a little bit, but then it just drops, and my network connection says its still connected.. If i boot the same machine to windows, i don't have this problem so i think it must be some kind of driver issue..

here is the output of my lspci :
