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.
Setting up your wireless router
IMPORTANT! Use wired connection in setting up your
wireless router to avoid possible setup problems due to
wireless uncertainty.
