Description

Wireless

Select Enable to enable the wireless function.

Country

Your device is configured for operation in the U.S. only.

Output Power

Set the strength of the wireless signal that the cable modem/router

transmits.

802.11 Band

Your device supports 2.4 GHz only.

802.11n-mode

In

Auto

mode, your cable modem/router will automatically adjust to avoid

interference with neighboring devices.

Bandwidth

Specify radio frequency bandwidth, either 20MHz single, or 40MHz (dual

channel), that the cable modem/router will use if 802.11n mode is

configured as Automatic and the Control Channel is configured as

Automatic.

Sideband for

Control Channel

(40 MHz only)

You may select Sideband and the secondary extension channels if your

cable modem/router is operating at 40 MHz bandwidth and the

802.11n-mode is configured as

Auto

.

Control Channel

Select the channel for AP operation next to the drop-down list box. The

current channel number is displayed. The list of detailed control channel

and extension channels are shown in the Table below.

Example 1

: If your control channel is set to 1, the extension channel will be transmitted on

channel 5. The total bandwidth of the signals on channel 1 and 5 equals 40 MHz.

Example 2

: If your control channel is set to 11, the extension channel will be transmitted on

channel 7. The total bandwidth of the signals on channel 11 and 7 equals 40 MHz.

Primary Network

The Primary Network page allows you to configure the primary wireless network and its security

settings. Strong security is the best way to prevent unauthorized wireless network access. This page

provides Automatic Security Configuration to simplify the configuration process.

•

Broadcom’s SecureEasySetup (SES) technology dramatically simplifies installation by

72

automating the processes of configuring new wireless networks and adding devices to

existing networks.

•

SES establishes a private connection between the devices and automatically configures the

network's SSID and WPA-Personal security settings. It configures a new network only on

each new device that is authorized to join the network.

To access the

Table 25. Primary Network Menu Option

Option

Description

Primary Network

Select Enable to enable primary wireless network.

Network Name (SSID)

Set the Network Name (also known as SSID) of the wireless

network. This is a 1-32 ASCII character string.

Closed Network

Select Enable to suppress broadcast of the SSID.

WPA

WiFi Protected Access (WPA) offers stronger encryption than

WEP. Enable WPA alone if you have a RADIUS server –

otherwise WPA-PSK.

WPA-PSK

Offers stronger encryption than WEP. When enabled, you must

also enter a Pre-Shared Key.

WPA2

Offers state-of-the-art security. Enable WPA2 alone only if you

have a RADIUS server; otherwise use WPA2-PSK.

WPA2-PSK

Offers state-of-the-art security. When enabled, you must also

enter a Pre-Shared Key below.

WPA/WPA2 Encryption

Select Enable to use WPA/WPA2 encryption.

WPA Pre-Shared Key

Enter a 8-63 ASCII character string if you have enabled

WPA-PSK or WPA2-PSK.

RADIUS Server

If you’re using a RADIUS server, enter it’s IP address here. The

RADIUS server may be on either public network (WAN) or

private network (LAN).

RADIUS Port

(Relevant only when the

RADIUS server is enabled)

Enter the UDP port number of the RADIUS server. The default

port is 1812.

RADIUS Key

(Relevant only when the

RADIUS server is enabled)

Enter the RADIUS Key.

Group Key Rotation Interval

(Relevant only when the

RADIUS server is enabled)

When enabled, the cable modem/router generates the best

possible random group key and updates all key-management

capable clients periodically. Set to zero to disable periodic

rekeying.

WPA/WPA2 Re-auth

Interval

Interval (in seconds) at which the cable modem/router (if using

WPA-PSK key management) or RADIUS server (if using WPA

key management) sends a new group key out to all clients. The

re-keying process is the WPA equivalent of automatically

changing the WEP key for an AP and all stations in a WLAN on a

periodic basis.

WEP Encryption

WEP Encryption can be set to WEP 128-bit, 64-bit, or Disable.

Both the wireless clients and the cable modem/router must use

the same WEP key.

Shared Key Authentication

Select Enable to enable. Shared Key authentication is only

available when WEP is enabled.

74

802.1x Authentication

(only available when WEP is

enabled)

Select Enable to enable 802.1x authentication.

Network Key 1-4

You can pre-define up to 4 keys for 64-bit or 128-bit WEP. 64-bit

keys require 10 hexadecimal digits and 128-bit key require 26

hexadecimal digits.

Current Network Key

Select one of the four pre-defined keys as the current network

key.

PassPhase

Enter a word or group of printable characters and click Generate

WEP keys to generate WEP encryption key. These characters are

case sensitive.

Generate WEP Keys

Click to generate 4 WEP keys automatically.

Automatic Security

Configuration

Select the mode of push button.

SES: SES (Secure Easy Setup) is a technology developed by

Broadcom. SES lets you configure the SSID and encryption

keys on both the cable modem/router and the client with

the press of a button.

y

WPS: WPS (WiFi Protected Setup) is a protocol to simplify

the process of configuring security on wireless networks.

Device Name

Enter a name to identify this cable modem/router in WPS

network.

WPS Setup AP PIN

PIN (Personal Identification Number) is the number of your PC

or game machine. When a WPS-supported device tries to connect

to this cable modem/router, you have to enter its PIN into the

WPS Setup AP’s PIN field, then click

Configure

.

WPS Add Client

Select WPS mode to be deployed.

Push-Button

In Push-Button mode, then user only needs to push the WPS

button on the cable modem/router. Then, within 2 minutes,

activate WPS on your client device(s).

PIN

For devices that require a PIN, enter the PIN in the WPS Add

Client PIN’s field, and then click

Add

.

Create SES Network

This action button generates a new SES network, applies the configuration to the wireless interface,

and stores the settings to non-volatile memory. It enables WPA-PSK authentication and generates a

unique Network Name (SSID) and random, 16-character Pre-Shared Key (PSK). The pop-up

window shown below informs the user a SES network has been successfully created.
