N900 Wireless Dual Band Gigabit Router WNDR4500
Changes Not Saved
If the router does not save the changes you make in the router interface, check 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 t
he web browser. The changes might have
occurred, but the old settings might be in the web browser’s cache.
Wireless Connectivity
If you are having 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 Wireless LEDs on the front of the rout
er. It should be lit. If it is not, you
can press the WiFi On/Off button on the back of the router to turn the router’s wireless
radio back on.
If you disabled the 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.)
• Doe
s your wireless device support the security that you are using for your wireless
n
etwork (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 see
(Basic Wireless Settings on p
age 23).
Note: Be sure to click Apply if
you make changes.
Wireless Signal Strength
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
ro
uter, but at least 6 feet away, and see whether the signal strength improves.
• Is your wireless signal blocked by object
s between the router and your computer?
Restore the Factory Settings and Password
This section explains how to restore the factory settings, changing the router’s administration
password back to password. You can erase the current configuration and restore factory
defaults in two ways:
• Use the
Era
se function of the router (see Erase on page 78).
