my problem: i am trying to share folders on my wifes computer and connect to it with my laptop and vise versa. but i am unsuccessful... i have a linksys WRT54G wireless router with 3 computers that i connect to it: 1. my desktop computer (connected directly to router) 2. my laptop computer (wireless) 3. my wife's desktop computer (wireless) i have file and print sharing turned on, on all 3 computers, i have my firewall turned off on all 3 computers, and i have some folders shared on all 3 computers. on my desktop computer i can see the shared folders on all 3 computers, but my laptop and wife's computer can only see the desktop shared items, not each other. i can ping all 3 from the desktop computer, but my laptop and wifes desktop can't ping each other. any suggestions???
