Step 1: Look in your router's instruction manual to find its internal IP address. The IP address is a series of numbers, broken up by periods. For example, a common IP address is 192.168.0.1.
Step 2: Open an Internet browser window, such as Firefox or Internet Explorer.
Step 3: Type the router's IP address into the address bar and click, "Enter." This will open a web page with your router's control panel.
Step 4: Enter your user information if required. The username will often default to "Admin" and then enter the personal password you set up when you originally created your wireless network.
Step 5: Access the "Wireless" link on the page.
Step 6: Enter your new wireless network name in the field labeled "Wireless Network Name." This field is also commonly labeled as "SSID" which stands for "Service Set Identifier." Your new wireless network name will be saved.
