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, 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.
•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 triple band technology, your wireless router supports 2.4GHz, 5GHz-1 and 5GHz-2 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.
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 official support site where software drivers, updates, and other related information can be obtained.
