2 Creating your network
Positioning your router
For the best wireless signal transmission between the wireless
router and the network devices connected to it, ensure that you:
• Place the wireless router in a centralized area for a maximum
wireless coverage for the network devices.
• Keep the device away from metal obstructions and away from
direct sunlight.
• Keep the device away from 802.11g or 20MHz only Wi-Fi
devices, 2.4GHz computer peripherals, Bluetooth devices,
cordless phones, transformers, heavy-duty motors, fluorescent
lights, microwave ovens, refrigerators, and other industrial
equipment to prevent signal interference or loss.
• Always update to the latest firmware.Visit the ASUS website at
http://www.asus.com to get the latest firmware updates.
• To ensure the best wireless signal, orient the three detachable
antennas as shown in the drawing below.
• For optimum performance, please switch on the cooling
system.

What you need
To set up your network, you need one or two computers that meet
the following system requirements:
• Ethernet RJ-45 (LAN) port (10Base-T/100Base-TX/
1000BaseTX)
• IEEE 802.11a/b/g/n wireless capability
• An installed TCP/IP service
• Web browser such as Internet Explorer, Firefox, Safari, or
Google Chrome
NOTES:
• If your computer does not have built-in wireless capabilities,
you may install an IEEE 802.11a/b/g/n WLAN adapter to your
computer to connect to the network.
• With its dual band technology, your wireless router supports
2.4GHz and 5GHz wireless signals simultaneously.This allows
you to do Internet-related activities such as Internet surfing or
reading/writing e-mail messages using the 2.4GHz band while
simultaneously streaming high-definition audio/video files
such as movies or music using the 5GHz band.
• If you are using only one computer with single band
IEEE 802.11b/g/n WLAN adapter, you will only be able to use
the 2.4GHz band.
• If you are using only one computer with dual band
IEEE 802.11a/b/g/n WLAN adapter, you will be able to use the
2.4GHz or 5GHz band.
• If you are using two computers with both
IEEE 802.11a/b/g/n WLAN adapters, you will be able to use
both 2.4GHz and 5GHz bands simultaneously.
• The Ethernet RJ-45 cables that will be used to connect the
network devices should not exceed 100 meters.

Setting up your wireless router
Wired connection
IMPORTANT!
• Use wired connection in setting up your wireless router to
avoid possible setup problems due to wireless uncertainty.
• Before setting up your ASUS wireless router, do the following:

your network.
• Disconnect the cables/wires from your existing modem
setup. If your modem has a backup battery, remove it as
well.
• Reboot your computer (recommended).
NOTE: Your wireless router has an integrated auto-crossover
function, so use either straight-through or crossover cable for
wired connection.
