It's a series of curving lines in the top-right side of the menu bar. Clicking it will invoke a drop-down menu. If you assigned a name to your router when setting it up, the name will appear here; otherwise, look for your router's brand and/or model number. For example, you might see "Cisco" and a series of numbers and letters for a Cisco router. You'll do so in the text field to the right of the "Password" heading.  If you didn't add a password to your network when setting up the router, the password (called a "Security Key") is on the back or bottom of the router unit. You can also check the "Remember this network" box to sign into this network automatically whenever you're in range. As long as your password is correct, this will connect your Mac to the wireless router.
