The CD that came with my Linksys Wireless (G) router is for PC only. How do I set up my router through the web interface when it needs a username and password? Do I just run the Setup wizzard (push the wizzard button on the front of the router) without the CD?

By default the username is blank with a password of "admin".

Once you log in, you can set it up yourself. The wizard button sets up the wireless security, which can be viewed from its own page.

http://192.168.1.1/ by default, and use blank user, pass admin.
depending on your isp settings, it may just go (cable, dhcp), might need to put in username/password (dsl, pppoe), or static ip info. then turning on the wep/wpa is under the wireless setting.

also you should go to the adminstration tab and set a password, then your user is admin and the pass is what you set.

Got it all set up and working... Thanks to all who replied.
