Positioning your router
To get the best wireless network performance from your wireless
router, follow the recommendations below:
• Place the wireless router at the center of your network for
maximum wireless coverage.
• 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.

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/1000Base-T)
• IEEE 802.11b/g/n wireless capability
• An installed TCP/IP service
• Web browser such as Microsoft Internet Explorer, Mozilla
Firefox, Apple Safari, or Google Chrome
• If your computer does not have built-in wireless capabilities,
install an IEEE 802.11b/g/n WLAN adapter to your computer
to connect to the network.
• With its dual band technology, your ADSL/VDSL router
supports 2.4GHz and 5GHz wireless signals simultaneously.
This allows you to browse the Internet or access e-mail
messages using the 2.4GHz band while streaming high-
definition audio/video files such as movies or music using the
5GHz band.
• If you are using only one computer with a 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 a 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 used to connect the network
devices should not exceed 100 meters.
