Can't get home network to work.

I've recently bought and install a Linxsys wireless (11S4
B v4) router to my desktop and DSL modem. Also a linxsys
wireless network card on my home laptop. I've got it
working to share my DSL internet connection, & the icon
on both computers shows that the network is connected.
But, I cannot get the computers set up to share files and
printers. I have been through the home network wizard
serval times on both computers. When a bridge connection
is made, my internet connection no longer works, and I
still cannot share files or computers. Any help?
