A unique name makes it a lot faster to find your router when you're going online, especially when you're in an area with many different Wi-Fi hotspots. Using your router's admin panel, you can change the name of your wireless network whenever you wish. A Wi-Fi network names is also called service set identifier, or SSID. Your router's SSID is case-sensitive. It can have up to 32 letters or numbers, but can't include spaces.
Look in your router's instruction manual to find its internal IP address, such as "192.168.0.1."

Type the router's IP address into the address bar of your Internet browser and press "Enter" to open a Web page with your router's control panel.
Enter your router's admin username and password as prompted. If you did not set these credentials, you will need to check with your router manufacturer's website to find the defaults. Often the default username is "admin" and the default password is blank.
Access the "Wireless" link on the page.
Enter your new wireless network name in the field labeled "Wireless Network Name." This field is also commonly labeled as "SSID." Save your changes.
Open the network settings for each Wi-Fi device and choose the new network name to connect to your router.
If you can't find your router's instruction manual, you can find the router's internal ID by using your computer. Go to "Start," click "Run" and enter "cmd." Type "ipconfig" into the Command Prompt window and press "Enter." Under the "Gateway" column, you will see your router's IP address.
Avoid SSID names that reveal your identity or location or that might invite intrusion. Naming your router "NSA surveillance van" is clever, but it may invite attack by unauthorized users.
Secure your wireless network by adding WPA2 encryption and a strong password to protect your network from intruders.
