using IPSec. Some VPN clients support traversal of IPSec through

NAT. This ALG may interfere with the operation of such VPN clients.

If you are having trouble connecting with your corporate network,

try turning this ALG oﬀ. Please check with the system administrator

of your corporate network whether your VPN client supports

NAT traversal.

Set the transmit power of the antennas.

This enables 802.11d operation. 802.11d is a wireless

speciﬁcation developed to allow implementation of

wireless networks in countries that cannot use the

802.11 standard. This feature should only be enabled

if you are in a country that requires it.

WMM is QoS for your wireless network. This will improve

the quality of video and voice applications for your

wireless clients.

Enable this option to reduce interference from

other wireless networks in your area. If the channel

width is operating at 40MHz and there is another

wireless network’s channel over-lapping and causing

interference, the router will automatically change to

20MHz.

Wi-Fi Protected Setup (WPS) System is a simpliﬁed method for securing your wireless network during the “Initial setup” as well

as the “Add New Device” processes. The Wi-Fi Alliance (WFA) has certiﬁed it across diﬀerent products as well as manufactures.

The process is just as easy as pressing a button for the Push-Button Method or correctly entering the 8-digit code for the Pin

Code Method. The time reduction in setup and ease of use are quite beneﬁcial, while the highest wireless Security setting of

WPA2 is automatically used.

This Wizard helps you add wireless devices to the wireless network.

The wizard will either display the wireless network settings to guide you through manual conﬁguration, prompt you to enter the

PIN for the device, or ask you to press the conﬁguration button on the device. If the device supports Wi-Fi Protected Setup and has a

conﬁguration button, you can add it to the network by pressing the conﬁguration button on the device and then the on the router

within 120 seconds. The status LED on the router will ﬂash three times if the device has been successfully added to the network.

There are several ways to add a wireless device to your network. A “registrar” controls access to the wireless network. A registrar

only allows devices onto the wireless network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup button on the

device. The router acts as a registrar for the network, although other devices may act as a registrar as well.

Click to start the wizard and skip to page 48.
