For more information about the WiFi radios, see Control the WiFi Radios on page 123. • If you disabled the modem router's SSID broadcast, your WiFi network is hidden and does not display in your WiFi client's scanning list. (By default, SSID broadcast is enabled.) For more information, see View or Change the Basic WiFi Settings on page 102. • Does your WiFi device support the security that you are using for your WiFi network (WEP, WPA, or WPA2)? For information about changing the WiFi security, see View or Change the Basic WiFi Settings on page 102. Tip If you want to change the WiFi settings of the modem router's main network, use a wired connection to avoid being disconnected when the new WiFi settings take effect. If your WiFi device finds your network but the signal strength is weak, check these conditions: • Is your modem router too far from your WiFi device or too close? Place your WiFi device near the modem router but at least 6 feet (1.8 meters) away and see whether the signal strength improves. • Are objects between the modem router and your WiFi device blocking the WiFi signal? Troubleshoot Your Network Using the Ping Utility Most network devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. You can easily troubleshoot a network using the ping utility in your computer or workstation.

To ping the modem router from a Windows computer: 1. From the Windows taskbar, click the Start button and select Run. 2. In the field provided, enter ping followed by the IP address of the modem router, as in this example: ping 192.168.0.1 3. Click the OK button.
