The WPS process automatically sets up your wireless computer with the network 
password when it connects. The modem router WPS screen displays a confirmation 
message. 
Specify Basic WiFi Settings
The modem router comes with preset security. This means that the WiFi network name 
(SSID), network key (password), and security option (encryption protocol) are preset in the 
factory. You can find the preset SSID and password on the modem router label. The preset 
SSID and password are uniquely generated for every device to maximize your wireless 
security.
NETGEAR recommends that you do not change your preset security settings. If you change 
your preset security settings, make a note of the new settings and store it in a safe place 
where you can easily find it.
If you use a wireless computer to change the wireless network name (SSID) or other wireless 
security settings, you are disconnected when you click the Apply button. To avoid this 
problem, use a computer with a wired connection to access the modem router.

o change the wireless channel, select a number in the  Channel list.
In some regions, not all channels are available. Do not change the chann\
el unless you 
experience interference (shown by lost connections or slow data transfe\
rs). If this 
happens, experiment with dif

ferent channels to see which is the best. 
When you use multiple access points, it is better if adjacent access poi\
nts use different 
channels to reduce interference. 
 The recommended channel spacing between adjacent 
access points is four channels (for example, use Channels 1 and 5, or 6\
 and 10).
10.  T
o change the mode, select it from the  Mode list.
Up to 145 Mbps is the default setting, which allows 802.1

If you connected wirelessly to the network and you changed the SSID, you are 
disconnected from the network.
12. Make sure that you can connect wirelessly to the network with its new settings. 
If you cannot connect wirelessly, check the following:
•Is your computer or wireless device connected to another wireless network in your 
area? Some wireless devices automatically connect to the first open network without 
wireless security that they discover.
•Is your computer or wireless device trying to connect to your network with its old 
settings (before you changed the settings)? If so, update the wireless network 
selection in your computer or wireless device to match the current settings for your 
network.
Change the WiFi Security Option
Your modem router comes with preset WPA2 or WPA security. The password that you enter to
