Configuring Your Wireless Network 234. 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 NetworkIf 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 243. 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 ConnectivityOnce 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 253. 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.
