How does one configure the wrt54g to connect to a laptop wirelessly, ONLY after a password authentification. My router lets any lappy connect. So basically how does one set up a password -and can I set it up wirelessly or will i have to connect the ethernet cable. Also whats this encryption stuff is it really required. Is that the missing link in my setup.... I have already got a user name and password assinged to the router and figured it would suffice . Obviously there is some thing I missed. Thanks in advance
