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.

This chapter describes how to configure your gateway’s Internet connection and add devices to your network. It includes the following sections:

• Set Up Your Wireless Network

• Set Up Wi-Fi Multimedia

• Change the Password

Note: Before changing wireless settings, connect the gateway and set up

its Internet connection as described in the DOCSIS3.0 N450 Wi-Fi Data Gateway CG3000Dv2 Quick Installation Guide.

NETGEAR DOCSIS 3.0 N450 Wi-Fi Data Gateway

Set Up Your Wireless Network

To set up the wireless network, you can enter wireless settings, or you can use Wi-Fi Protected Setup (WPS). To wirelessly connect to the gateway, a computer or wireless device must be configured with the same wireless settings as the gateway.

Configure Wireless Settings Manually

You can manually configure the wireless settings and security 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.

4. Specify the Wireless Network settings for your network:

• Name (SSID). The name of the wireless network.

The default wireless network name (SSID) for the gateway appears on the label of the gateway . You can enter a different name here for better wireless security and to make it easier to recognize your network when you want to connect to it wirelessly.

• 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 217 Mbps by default. You can specify the

mode to support faster equipment or legacy equipment.

5. Specify the security options:

• By default the gateway works with WP A and WPA 2 wireless security . You can specify the

network key, which works like a password to access the wireless network.

a. Set up WPA or WPA2 wireless security.

• WP A-PSK. This setting provides the TKIP encryption type and a pre-shared key.

• WP A2-PSK. This setting provides the AES encryption type and a pre-shared key.

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 setting that you select, enter the required information.

For WP A-PSK or WPA2-PSK, enter the pre-shared key , which is a password between 8

and 63 characters. The default WPA password appears on the label 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 .

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 on page 35.

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 13). After that, you can still use WPS to set up the wireless connection for

the computers that support WPS.
