Adding security to your router prevents unwanted parties from logging in and accessing the Internet through your network. Before you can add wireless security to your Motorola SBG900 router, you need to set up the router so it broadcasts a wireless network. Once the wireless is set up, use the Security section of the router's administration panel to add encryption and password protection.
Set Up Your Wireless Network
Open a new Web browser tab and visit your Motorola router's login page. If this link does not work on your device, copy and paste the following address directly into your browser's address bar:
Log in using the router's administrative user ID and password. If you've never logged in before, the default user ID for the SBG900 is "admin" and the default password is "motorola".
Click "Wireless" on the menu on the left of the page and then select the "Network" tab.
Place a check mark in the "Enable Wireless Interface" check box.
Enter an identifying name for your wireless network in the ESSID field. This is the name you will see when attempting to access your Wi-Fi connection from your computer and other wireless devices.
Click the "Channel" drop-down menu and select a random number. It does not matter which number you select.
Click "Save Changes" to finish enabling the router's wireless networking capabilities.
Add Wireless Network Security
Click "Wireless" on the main menu on the left of the router's administration panel.
Select the "Security" tab.
Click the "WPA" radio button and then click "Apply."
Press the "AES" radio button under the WPA Configuration heading.
Click the "Local (WPA - PSK) radio button.
Enter a password for your wireless network in the "PSK Passphrase" field. This is the password people will use when attempting to access your wireless network. The password must be at least 8 and no more than 63 characters long.
Click "Save Changes" to finish setting up the router's wireless security.
When selecting a password for your router, choose one that’s easy for you to remember but difficult for strangers to guess. Although the password can be up to 63 characters, it does not need to be nearly that long in order to be effective. Write down the password and keep in a safe place.
The SBG900 also supports WEP network security, but this type of encryption is generally less secure than WPA. Only use WEP if your computer or mobile device doesn’t support WPA. Most modern devices support WPA.
