Ok here is the deal Cable modem going to a Linksys WRT54G From there I have my desktop (wired) into the router I also connect up with a IBM thinkpad wireless. My problem is both machines surf and do everything you would expect but I can not Ping or RDP from the the IBM to the desktop or the other way around. What do I need to do to get this to work? Do I need any additional hardware? Thanks for the help.
