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 the note in a safe

place where you can easily find it.

If you use a wireless computer to change the 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.

Name (SSID)

field.

The name can be up to 32 characters long and is case-sensitive. The default SSID is

In some regions, not all channels are available. Do not change the channel unless you

experience interference (shown by lost connections or slow data transfers). If this

happens, experiment with different channels to see which is the best.

When you use multiple access points, it is better if adjacent access points use different

channels to reduce interference. NETGEAR recommends channel spacing between

adjacent access points of four channels (for example, use Channels 1 and 5, or 6 and

10).

9.

To change the mode, select it from the

Mode

list.

Up to 145 Mbps

300-Mbps

setting allows

802.11n devices to connect at this speed.

Apply

button.

Your settings are saved.

If you used WiFi to connect to the network and you changed the SSID, you are

disconnected from the network.

11.

Make sure that you can connect with WiFi to the network with its new settings.

If you cannot connect, check the following:

•

Is your computer or wireless device connected to another WiFi 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

connect to your network is unique to your modem router and is on the modem router label.

NETGEAR recommends that you use the preset security, but you can change the password.

NETGEAR recommends that you do not disable security.
