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

to get the latest firmware updates.

•

To ensure the best wireless signal,orient the two detachable

antennas as shown in the drawing below.

Setup Requirements

To set up your wireless network, you need a computer that meets

the following system requirements:

• Ethernet RJ-45 (LAN) port (10Base-T/100Base-TX/1000Base-

TX)

• IEEE 802.11a/b/g/n/ac 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/ac 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.

•

Some IEEE 802.11n devices that you want to connect to your network

may or may not support 5GHz band. Refer to the device's manual for

specifications.

•

The Ethernet RJ-45 cables that will be used to connect the network

devices should not exceed 100 meters.
