Wireless Performance and Gateway Location
The range of your wireless connection can vary based on the physical placement of the gateway. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.
For best results, place your gateway according to the following guidelines:
•Near the center of the area in which your computers operate.
•In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls).
•Away from sources of interference, such as computers, microwave ovens, and 2.4 GHz cordless phones.
•Away from large metal surfaces.
•To provide the best side-to-side coverage, put the gateway in a vertical position.
•The time it takes to establish a wireless connection can vary depending on both your security settings and the gateway location. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.
Log In to Your Gateway
Log in to the gateway to view or change its settings.
Note: To connect to the gateway, use a computer configured for DHCP (most computers are). For help with configuring DHCP, see the instructions that came with your computer.
When you have logged in, if you do not click Logout, the gateway waits for 5 minutes after there has been no activity before it automatically logs you out.
To log in to the gateway:
1.On the computer that is connected to the gateway with an Ethernet cable, type http://192.168.0.1 in the address field of your Internet browser.

Note: Before changing wireless settings, connect the gateway and set up its Internet connection as described in the DOCSIS3.0 N900 Wireless Data Gateway CG4500BD Quick Installation Guide.
This chapter includes the following sections:
•Set Up Your Wireless Network
•Configure Wireless Settings Manually
•Use Push 'N' Connect (WPS) Wireless Setup
•Set Up Wi-Fi Multimedia

NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
Set Up Your Wireless Network
To set up the wireless network, you can enter wireless settings, (see Configure Wireless Settings Manually on page 12), or you can use Wi-Fi Protected Setup (WPS), (see Use Push 'N' Connect (WPS) Wireless Setup on page 15). To wirelessly connect to the gateway, a computer or wireless device must be configured with the same wireless settings as the gateway.
•The default wireless network name (SSID) for the gateway is the last six digits of the WiFi MAC address. NETGEAR recommends that you change this name for better wireless security and to make it easier to recognize your network when you want to connect to it wirelessly.
•By default the gateway works with WPA and WPA 2 wireless security. The default password is the 13-character device serial number.
•To use Push 'N' Connect (WPS), your wireless computers and equipment must support WPS technology. See Use Push 'N' Connect (WPS) Wireless Setup on page 15.
Configure Wireless Settings Manually
You can manually configure the wireless settings and security for both the 2.4 GHz and
5GHz networks in the Wireless Settings screen.
To view or configure the wireless settings:
1.If you are located near the gateway, use an Ethernet cable to connect your computer to the gateway while you are changing the wireless settings.
Note: If you connect wirelessly to the gateway and then change its wireless network name (SSID) or wireless security, you will be disconnected after you click Apply.
2.Log in to the gateway.
For more information, see Log In to Your Gateway on page 8.
3.In the main menu, under Setup, select Wireless Settings.

NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
4.Specify the Wireless Network settings for each network:
•Name (SSID). The name of the wireless network.
•Region. The location where the gateway operates.
•Channel. The available channels depend on the region. Some countries have laws specifying which channels should be used. To reduce interference when using more than one access point, NETGEAR recommends using 5-channel spacing between adjacent access points (for example, use Channels 1 and 6, or 6 and 11).
•802.11 Mode. This value is set to Up to 145 Mbps by default. You can specify the mode to support faster equipment or legacy equipment.
5.Specify the security options for either the 2.4 GHz or the 5 GHz network or both.
By default the gateway is set up to work with both WPA and WPA2 wireless security. (This security option is already selected.) You can specify the network key, which works like a password to access the wireless network.
a. Set up WPA or WPA2 wireless security:
•WPA-PSK. This setting provides the TKIP encryption type and a pre-shared key password.
•WPA2-PSK. This setting provides the AES encryption type and a pre-shared key password.
Note: Configure your wireless computers with the same WPA2 or WPA settings as your gateway so that you can connect.
b.Depending on the WPA settings that you select, enter the required information.
For WPA-PSK or WPA2-PSK, enter the pre-shared key, which is a password between 8 and 63 characters. The default WPA password is the 13-character serial number of your gateway.
Note: By default, the gateway is set up to work with WPA and WPA2 wireless security, both of which are newer than WEP. Typically, the only reason you might need to set up WEP would be to allow access to older wireless computers or devices that cannot support WPA.
6. Click Apply.
Wireless Configuration

NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
Note: If you plan to use WPS, and you want to keep your wireless settings the same, go to the Advance Wireless Settings screen and make sure that the Keep Existing Settings check box is selected. See
Advanced Wireless Settings (2.4 GHz and 5 GHz)on page 29.
Use Push 'N' Connect (WPS) Wireless Setup
Push 'N' Connect (WPS) can be a quick way to automatically set up your gateway’s wireless network and set up your wireless computer to connect to it at the same time. WPS, also called Wi-Fi Protected Setup, is relatively new technology, so before you decide to use it, check to make sure your wireless computers and devices support WPS. Look for the
symbol on all the computers that connect wirelessly to the gateway.
If you do not see the symbol on all the computers that connect to the wireless network, then you should manually set up your network first (see Configure Wireless Settings Manually on page 12). After that, you can still use WPS to set up the wireless connection for the computers that support WPS.
Note: All WPS-capable products should be compatible with the gateway. For more information about the WPS standard, visit http://www.wi-fi.org).
Two Push 'N' Connect methods are available, WPS button and PIN (personal identification number).
Add a Client Using the WPS Button
Note: The first time you use WPS, it assigns a random network name (SSID) and a random password to your wireless network. If you want to keep the network name and password you specified in the Wireless Settings screen, you must select the Keep Existing Settings check box in the Advanced Wireless Settings screen. See
Advanced Wireless Settings (2.4 GHz and 5 GHz) on page 29.
Any computer or wireless device that connects wirelessly to the gateway is a client. After a device is added as a client, it can automatically connect to the gateway.
To add a wireless device to your gateway using the WPS button:
1. Make sure that you know how WPS works on your computer or wireless device.
Wireless Configuration
15
NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway
If it works with WPS, it has a WPS utility and might also have a WPS button that you can press.
2.Log in to the gateway.
For more information, see Log In to Your Gateway on page 8.
3.In the main menu, select Add WPS Client.
4.Click Next.
The Add WPS Client screen displays:
5.Either click the 
WPS button, or press the 
button on the front of the gateway.
•The WPS LED on the front of the gateway begins to blink.
•The gateway tries to communicate with the wireless computer or device for 2 minutes.
•If the security option in the Wireless Settings screen was set to Disable, it is automatically changed to WPA-PSK [TKIP] + WPA2-PSK [AES], including a random wireless security password.
6.Go to the wireless computer, and run its WPS configuration utility.
7.To click the WPS button, follow the utility’s instructions.
When the computer connects to the wireless network, the gateway sends its SSID and WPA-PSK or WPA2-PSK configuration to that computer.
8.On the computer that just joined the wireless network, make sure you can connect to the Internet.
