more settings

The following settings are available in this screen:

Enable Wireless Router Radio

. You can completely turn off the wireless portion of the

wireless router by clearing this check box. Select this check box again to enable the wireless

portion of the router. When the wireless radio is disabled, other members of your household

can use the router by connecting their computers to the router with an Ethernet cable.

Enable 20/40 MHz Coexistence

. This is for the 2.4 GHz band only. The 20/40 MHz

coexistence function is enabled by default when the wireless mode is set to Up to 300 Mpbs

(40 MHz), which is required for Wi-Fi certification. This check box is grayed out if the wireless

mode is set to Up to 130 Mbps.

The router can run in either 40 MHz mode or 20 MHz mode when the wireless mode is set to

Up to 300 Mbps. When the Enable 20/40 MHz Coexistence check box is selected, the router

runs in 40 MHz mode unless there is another nearby WiFi network in the area already

running in 40 MHz mode or there is a wireless access point on the secondary channel. If that

happens, the router runs in 20 MHz mode to coexist with that network.

If you want the router to always run in 40 MHz mode, clear this check box and click

Apply

.

Note:

The Fragmentation Length, CTS/RTS Threshold, and Preamble

Mode options are reserved for wireless testing and advanced

configuration only. Do not change these settings.

Transmit Power Control

. You can change the transmit power of each wireless radio. A

lower setting for transmit power reduces the power consumption of the router but also

reduces the wireless coverage.

Turn off wireless signal by schedule

. You can use this feature to turn off the wireless signal

from your router at times when you do not need a wireless connection. For example, you

could turn it off for the weekend if you leave town.

WPS Settings

.You can add use Wi-Fi Protected Setup (WPS) to join the wireless network.

See

Wi-Fi Protected Setup (WPS) Method

•

Router's PIN

. You can use this number to join the wireless network using WPS from a

computer or wireless device. The Router’s PIN has to be enabled for you to do this.

•

Enable Router's PIN

. You can configure the router's wireless settings or add a wireless

client through WPS using the router's PIN only when the PIN is enabled.

•

Auto Disable PIN

. Selecting this check box causes the PIN to stop working after the

number of failed PIN connections that you specify.

This setting protects the router from a brute force attack. If the PIN is disabled

automatically, it remains disabled until the router reboots or you log in to the router and

change the setting by selecting the Enable Router's PIN check box and clicking the Apply

button.

•

Keep Existing Wireless Settings

. Leave this check box selected so that the wireless

settings stay the same when a wireless computer or device uses WPS to join the

network.

If you clear this check box, and someone uses WPS to join the network, the wireless

SSID and WPA2 or WPA password are automatically changed to random values. In

addition, if this option is selected, some software such as Network Explorer on Windows

Vista might not detect the wireless network.

Wireless Card Access List

. Click the

Set Up Access List

button display the Wireless Card

Access List screen. You can restrict access to your network to specific devices based on their

MAC address.

Restrict Wireless Access by MAC Address

You can set up a list of computers and wireless devices that are allowed to join the wireless

network. This list is based on the unique MAC address of each computer and device.

Each network device has a MAC address, which is a unique 12-character physical address,

containing the hexadecimal characters 0–9, a–f, or A–F only, and separated by colons (for

example, 00:09:AB:CD:EF:01). Typically, the MAC address is on the label of the wireless

card or network interface device. If you do not have access to the label, you can display the

MAC address using the network configuration utilities of the computer. You might also find

the MAC addresses in the Attached Devices screen.



To restrict access based on MAC addresses:

1.

On the Advanced Wireless Settings screen, click the

Setup Access List

to display the

Wireless Card Access List.

2.

Click

Add

to add a wireless device to the wireless access control list.

The Wireless Card Access Setup screen opens and displays a list of currently active

wireless cards and their Ethernet MAC addresses.

3.

If the computer or device you want is in the Available Wireless Cards list, select that radio

button; otherwise, type a name and the MAC address. You can usually find the MAC

address on the bottom of the wireless device.

Tip:

You can copy and paste the MAC addresses from the Attached Devices

screen into the MAC Address field of this screen. To do this, use each

wireless computer to join the wireless network. The computer should

then appear in the Attached Devices screen.

4.

Click

Add

to add this wireless device to the Wireless Card Access List. The screen changes

back to the list screen.

5.

Add each computer or device you want to allow to connect wirelessly.

Wireless AP

You can set up the router to run as an access point (AP) on the same local network as

another router.



To set up the router as an AP:

1.

Select

Advanced > Advanced Setup > Wireless AP

.

2.

Select the

Enable Access Point Mode

3.

Scroll down to view the bottom half of the screen to display more instructions.

4.

Use an Ethernet cable to connect the Internet port of this router to a LAN port in the other

router.

5.

Select the check box for the IP address setting that you want to use:

•

Get an IP address dynamically from the other router

. The other router on the

network assigns an IP address to this router while this router is in AP mode.

•

Fixed IP address (not recommended)

. Use this setting if you want to manually

assign a specific IP address to this router while it is in AP mode. Using this option

effectively requires advanced network experience.

Wireless Repeating Function (WDS)

You can set the router up to be used as a wireless access point (AP). Doing this enables the

router to act as a wireless repeater. A wireless repeater connects to another wireless router

as a client where the network to which it connects becomes the ISP service.

Wireless repeating is a type of Wireless Distribution System (WDS). A WDS allows a wireless

network to be expanded through multiple access points instead of using a wired backbone to

link them. The following figure shows a wireless repeating scenario.
