• Does the WiFi device that you are using find your WiFi network?
If not, check the WiFi LED
WiFi radios might be disabled. For more information about the WiFi radios, see
the WiFi Radios
• 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
the Main Network
• 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
the Basic WiFi Settings and WiFi Security of the Main Network
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?
