2 Creating your network
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.

Before you proceed
IMPORTANT!
• The Ethernet RJ-45 cables that will be used to connect the
network devices should not exceed 100 meters.
• 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 transformers, heavy-duty
motors, fluorescent lights, microwave ovens, refrigerators,
and other industrial equipment to prevent signal
interference or loss.
