Incorrect Date or Time
Select ADVANCED > Security > Schedule to display the current date and time. The wireless modem router uses the Network Time Protocol (NTP) to obtain the current time from one of several network time servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include the following:
•Date shown is January 1, 2000. This value means the wireless modem router has not yet successfully reached a network time server. Check that your Internet access is configured correctly. If you have finished setting up the wireless modem router, wait at least 5 minutes, and check the date and time again.
•Time is off by one hour. The wireless modem router does not automatically sense daylight saving time. In the Schedule screen, select the Automatically adjust for daylight savings time check box.
Wireless Connectivity
If you are having trouble connecting wirelessly to the wireless modem router, try to isolate the problem.
•Does the wireless device or computer that you are using find your wireless network?
If not, check the Wireless LEDs on the front of the wireless modem router. They should be lit. If they are not, you can press the WiFi On/Off button on the front of the wireless modem router to turn the wireless modem router’s wireless radio back on.
If you disabled the wireless modem router’s SSID broadcast, then your wireless network is hidden and does not show up in your wireless client’s scanning list. By default, SSID broadcast is enabled.
•Does your wireless device support the security that you are using for your wireless network (WPA or WPA2)?
