i have a wired network in my home , it has 4 pcs all connected through a dlink adsl wired router. i recently brought a laptop which has bulit in 802.11g i was wondering if i can put a PCI 802.11g card into one computer and BRIDGE this connection to my LAN? if this would work would i be able to share my internet connection through this bridge to the laptop

any help would be great thank you
