Motorola SBG900 Security Setup
Setting up the Motorola SURFboard Wireless Cable Modem Gateway is fairly strait forward. This Guide will walk you through setting up the wireless name (SSID) and wireless security (WPA). For this guide, we chose WPA for the security because the keys are easier to remember. This guide assumes that the gateway has been plugged in properly to the service provider and to the computer. To perform this setup, you have to use a computer pluged directly into the gateway. Using wireless to setup the gateway will lock you out!
1. For the first step we are going to log in to the gateway. Open up a web browser (Internet Explorer, Firefox) on the computer that is directly connected to the gateway. The gateway will normally assign your computer an IP address in the 192.168.100.??? range, which means we need to navigate to the web page http://192.168.100.1. type this into the address bar and press enter. The page that loads will look like this:
2. The default User ID is admin and the password is motorola. Once you have typed those in correctly, click "Log In." After that, the page will change. The page may differ but it will most likely look like this:
3. From this point we need to navigate to the wireless section. On the left of the screen there is a side bar. We need to select the third on down from the top, labeled "Wireless." Once it is clicked, it will turn blue and the page will change.
4. The first thing we are going to do is change the name that is displayed for the wireless network, also known as the ssid or ESSID. To change this, we need to navigate to the "Network" tab on the top of the screen. To rename your wireless network, change the field to the right of ESSID. The default name is Motorola and in my example picture it will stay the same. One the name has been changed, chick "Save Changes" at the bottom of the page.
5. Now we will move onto the security settings. On the top of the page, next to the Network tab, is the "security" tab: Click it. Now, on the page there is a "Secuirty Mode" section. Under it, there are three options. Click the radial button next to WPA and then "Apply." Now your page should look like this:
6. At the bottom of the page a field to the left of "PSK Passphrase" has turned white. In that white field, type in a passphrase (or password) that you would like for your wireless network. This passphrase will be required for anyone who wishes to use your internet connection wirelessly. The passphrase must be eight characters or longer to be acceptable. I would also recommend not using the name of your wireless for the passphrase, because that will create a security vulnerability. After the passphrase is entered, click "Save Changes."
7. Congratulations you're done! You can now either click "log out," located on the side bar, or just close the browser. Now, when ever a computer attempts to connect wirelessly, this passphrase will be required.
