Network sharing problems

[SuJu]

Hi everyone, I'm having a problem with file sharing. I have two computers, both running Windows XP Pro SP1. One of them are using a wireless card. I have a Linksys Wireless-G Broadband Router. The wierd thing is that one computer (the one connected with a wire to the router) can access the other computer's files fine, but teh second computer sees the workgroup but does not see the shared folders and when I click on the 1st workgroup computer through the 2nd computer, it says it does not permission, but the other way around it works. All firewalls are disabled so wats the problem?
