Configuring Your Wireless Settings and Security 
Options
The wireless network settings of the router must match the wireless network settings of any 
wireless devices that connect wirelessly to the router (such as wireless adapter cards and wireless 
computers). 
For a wireless connection, the router and each wireless computer must use the same SSID, also 
called the wireless network name, and the same wireless security. NETGEAR strongly 
recommends that you use wireless security. 
The Wireless Settings screen lets you set your wireless network connections and the wireless 
security option for your network and router. To configure the wireless network, you can either 
manually specify your network name (SSID) and your wireless security settings (see “Setting 
Your SSID and Wireless Security Manually” on page 20) or, if the clients in your network are 
WPS capable, you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and 
implement WPA/WPA2 security on both the router and the client device (see “Using Push N 
Connect (WPS) to Configure Your Wireless Network” on page 23). 
For a complete overview of all the security configurations that can be implemented on this router, 
see the online User Manual. A link to the User Manual is on the Resource CD.
Setting Your SSID and Wireless Security Manually
To specify the wireless settings, you must know the following:
• Name (11N 2.4 GHz SSID). The default is NETGEAR. 
• Name (11N 5 GHz SSID). The default is NETGEAR-5G.
Indoors, computers can connect over wireless networks at a range of several 
hundred feet. This can allow others outside of your immediate area to access your 
network.
If you configure the router from a wireless computer and you change the router’s 
SSID, channel, or security settings, you will lose your wireless connection when 
you click Apply. You must then change your computer’s wireless settings to match 
the router’s new settings. To avoid this situation, you can use a computer that is 
connected to the router with an Ethernet cable.

8.Click Apply to save your changes.
To set up your computers for wireless connectivity:
1.
Program the wireless settings of each computer or wireless adapter to have the same SSID 
(wireless network name) as the router.
2.Check that the wireless adapter on each computer can support the mode and security option 
that you selected. (If you have a question, see the online User Manual or review the settings 
you selected in “Configuring Your Wireless Settings and Security Options” on page 20).
3.Check that the security settings on each wireless device match the security settings of the 
router. For example, if you selected a security option requiring a passphrase, then the same 
passphrase must be used for each wireless computer.
The SSID of any wireless adapters must match the SSID you configure in the 
N750 wireless gigabit router. If they do not match, you will not get a wireless 
connection.
If you are configuring the router from a wireless computer and you change the 
router’s SSID, channel, or security settings, you will lose your wireless connection 
when you click Apply. You must then change the wireless settings of your 
computer to match the router’s new settings. 
						

							Configuring Your Wireless Network 23
4.Check that each wireless computer has a wireless link and is able to obtain an IP address by 
DHCP from the router. 
To access the Internet from any computer connected to your N750 wireless gigabit router, launch a 
browser such as Microsoft Internet Explorer or Mozilla Firefox.
Using Push N Connect (WPS) to Configure Your Wireless 
Network
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure 
the router’s SSID and security settings and, at the same time, connect the wireless client securely 
and easily to the router. Look for the   symbol on your client device.
1 WPS automatically 
configures the SSID and wireless security settings for the router (if the router is in its default state) 
and broadcasts these settings to the wireless client. 
If the router has already been configured manually or by using the Smart Wizard, and any of these 
security options have been enabled (WEP with auto authentication, WPS-PSK, WPA2-PSK, or no 
security), a wireless client can be added to your network quickly and simply by using Push N 
Connect. In this case, the existing wireless settings are broadcast to the WPS-capable client. (For 
more information on setting up a mixed network, see the online User Manual. A link to the User 
Manual is on the Resource CD.)
The following instructions assume that you are configuring WPS on the router for the first time 
and connecting a WPS-capable device such as a wireless computer or wireless adapter. 
To connect a device using WPS:
1.
Open the networking utility of the device you want to connect to that supports WPS. 
2.Push the N750 wireless gigabit router’s WPS button, then release. The WPS LED will start to 
blink.
For a Windows PC, go to the Control Panel and select Network Connections. 
Check the Wireless Connections Properties and ensure that TCP/IP Properties 
are set to Obtain an IP address automatically.
1. For a list of other Wi-Fi-certified products available from NETGEAR, go to http://www.wi-fi.org.
NETGEAR’s Push N Connect feature is based on the Wi-Fi Protected Setup 
(WPS) standard. All other Wi-Fi-certified and WPS-capable products should be 
compatible with NETGEAR products that implement Push N Connect. 
						

							Configuring Your Wireless Network 24
3.While the WPS LED is blinking, you have 2 minutes to enable WPS on the device you are 
connecting to. The blinking ceases when one of these two conditions occurs:
• WPS has enabled security between the router and the other device.The router has 
generated an SSID, implemented WPA/WPA2 wireless security (including a PSK security 
password) on the router and has sent this configuration to the wireless client.
• If you do not establish a connection using WPS during this 2-minute interval, your router 
security and SSID (wireless network name) will be restored to the default settings (router 
security will be set to None). 
The WPS LED will stop blinking or turn off, depending on whether the wireless device has 
connected successfully.
4.Note the new SSID and WPA/WPA2 password for the wireless network.
To access the Internet from any computer connected to your N750 wireless gigabit router, launch a 
browser such as Microsoft Internet Explorer or Firefox. 
For more information about setting up your wireless network and configuring your wireless 
security settings, see the User Manual. A link to the online User Manual is on your Resource CD.
Testing Basic Wireless Connectivity
Once you have established basic wireless connectivity and enabled security settings appropriate to 
your needs, you can test connectivity between devices connected to your router.
To test basic wireless connectivity: 
1.
Log in to the N750 wireless gigabit router at http://www.routerlogin.net, using the default 
user name of admin and default password of password, or using whatever LAN address and 
password you have set up.
2.Select Wireless Settings from the main menu of the N750 wireless gigabit router.
If you are planning a mixed network of WPS capable devices and non-WPS capable 
devices, NETGEAR suggests that you set up your wireless network and security 
settings manually first, and use WPS only for adding additional WPS capable 
devices.  
						

							Configuring Your Wireless Network 25
3.Note your SSID name. If you used WPS to establish a connection with other devices, the SSID 
will now be a randomly selected name. 
4.Make sure that you have selected the region in which the wireless router will operate. 
5.Check the Wireless mode. The default is Up to 450Mbps at 5GHz & 145Mbps at 2.4GHz. If 
you are experiencing interference, try selecting one of the other available settings (see 
“Configuring Your Wireless Settings and Security Options” on page 20).
6.Check your wireless security. If you used WPS to enable wireless security, your security will 
be set to WPA/WPA2 with a randomly-selected PSK security password. 
7.Click Apply to save any changes.
8.Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same wireless network name 
(SSID) as the N750 wireless gigabit router and the same wireless security as your N750 
wireless gigabit router. Check that they have a wireless link and are able to obtain an IP 
address by DHCP from the router.
Your N750 wireless gigabit router is now configured to provide Internet access for your network. 
Your N750 wireless gigabit router automatically connects to the Internet when one of your 
computers requires access. It is not necessary to run a dialer or login application such as Dial-Up 
Networking or Enternet to connect, log in, or disconnect. These functions are performed 
automatically by the N750 wireless gigabit router as needed.
To access the Internet from any computer connected to your N750 wireless gigabit router, launch a 
browser such as Microsoft Internet Explorer or Mozilla Firefox.
For more information on setting up your wireless network and configuring your wireless security 
settings, see the User Manual. A link to the online User Manual is on your Resource CD.
The SSID of any wireless adapters or wireless devices connected to your router 
must match the SSID you configured in the N750 wireless gigabit router. If they 
do not match, you will not get a wireless connection.
If you are configuring the router from a wireless computer and you change the 
router’s SSID, channel, or security settings, you will lose your wireless 
connection when you click Apply. You must then change the wireless settings of 
your computer to match the router’s new settings.
