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
on page
19.
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.
6.
Select the
Turn Access Control On
check box.
7.
Click
Apply
.
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
check box.

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.
