1.4 Positioning your wireless router
For optimal wireless transmission between the wireless router and
connected wireless devices, ensure that you:
• Place the wireless router in a centralized area for a maximum
wireless coverage for the network devices.
• Keep the wireless router away from metal obstructions and
away from direct sunlight.
• Keep the wireless router away from 802.11g or 20MHz only
Wi-Fi devices, 2.4GHz computer peripherals, Bluetooth devices,
cordless phones, transformers, heavy-duty motors, uorescent
lights, microwave ovens, refrigerators, and other industrial
equipment to prevent signal interference or loss.
• Always update to the latest rmware. Visit the ASUS website at
http://www.asus.com to get the latest rmware updates.
• Orient the antennas as shown in the drawing below.

1.5 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/1000BaseTX)
• IEEE 802.11a/b/g/n/ac/ax 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/ax 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 surng or reading/writing
e-mail messages using the 2.4GHz band while simultaneously
streaming high-denition audio/video les 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
specications.
• The Ethernet RJ-45 cables that will be used to connect the network
devices should not exceed 100 meters.
IMPORTANT!
• Some wireless adapters might have connectivity issues to 802.11ax
WiFi APs.
• If you’re experiencing such issue, please ensure you update the driver
to the latest version. Check your manufacturer's ocial support site
where software drivers, updates, and other related information can
be obtained.
