IP Address for Linksys Wireless Router

I have been using a Linksys Wireless router connected to a Linksys phone adapter (Vonage). I would like to use a D-Link wireless adapter to connect a PC to the wireless router. How do I set the SSID settings in the wireless router? Windows does not automatically detect the available connections. I had once set the SSID name, but I now forgot how I got to the settings. I would appreciate any help.

Thanks.
