2 Creating your network

Positioning your router

For the best wireless signal transmission between the ADSL router and the network devices connected to it, ensure that you:

• Place the ADSL 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 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.

• To ensure the best wireless signal, orient the three detachable antennas as shown in the drawing below.

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 ADSL 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.

• The Ethernet RJ-45 cables that will be used to connect the network devices should not exceed 100 meters.

Connecting your devices

Wired connection

IMPORTANT!

• Use wired connection in setting up your ADSL router to avoid possible setup problems due to wireless uncertainty.

• Before setting up your DSL-N55U, do the following:

• Disconnect the cables/wires from your existing modem

setup. If your modem has a backup battery, remove it as well.

• Reboot your computer (recommended).
