Netgear WNDR4500v3 – N900 WiFi Dual Band Gigabit Router—Premium Edition 사용자 설명서

If the router does not save the changes that you make in the router interface, do the 
following:

When entering configuration settings, always click the Apply button before moving to 
another screen or tab, or your changes are lost. 

Click the Refresh or Reload button in the web browser. It is possible that the changes 
occurred, but the old settings might be in the web browser’s cache.

If you are experiencing trouble connecting wirelessly to the router, try to isolate the problem: 

Does the wireless device or computer that you are using find your wireless network?

If not, check the WiFi LED on the front of the router. If it is off, you can press the WiFi 
On/Off button on the router to turn the router wireless radios back on.

If you disabled the router’s SSID broadcast, then your wireless network is hidden and 
does not display 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)?

If you want to view the wireless settings for the router, use an Ethernet cable to connect a 
computer to a LAN port on the router. Then log in to the router, and select Wireless. 

Be sure to click the Apply button if you change settings.

If your wireless device finds your network but the signal strength is weak, check these 
conditions:

Is your router too far from your computer or too close? Place your computer near the 
router but at least 6 feet (1.8 meters) away and see whether the signal strength improves.

Are objects between the router and your computer blocking the wireless signal?

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. 

You can ping the router from your computer to verify that the LAN path to your router is set up 
correctly.
