Step 8 Keep the default SSID (wireless network name) or change it to a desired name, so you

can always recognize your wireless network with it. Click Next.

18

Menu Description

Mode Please select the radio band from one of the following options.

2.4GHz(B): 2.4GHz band, only allows 802.11b wireless network
client to connect to this router (maximum transfer rate 11Mbps).

2.4 GHz (N): 2.4GHz band, only allows 802.11n wireless network
client to connect to this router (maximum transfer rate 150Mbps).

2.4 GHz (B+G):2.4GHz band, only allows 802.11b and 802.11g
wireless network client to connect to this router (maximum
transfer rate 11Mbps for 802.11b clients, and maximum 54Mbps
for 802.11g clients).

2.4 GHz (G): 2.4GHz band, only allows 802.11g wireless
network client to connect to this router (maximum transfer rate
54Mbps).

2.4 GHz (B+G+N): 2.4GHz band, allows 802.11b, 802.11g, and

802.11n wireless network client to connect this router (maximum
transfer rate 11Mbps for 802.11b clients, maximum 54Mbps for

802.11g clients, and maximum 150Mbps for 802.11n clients).

SSID This is the name of the wireless network. You can type any

alphanumerical characters here, maximum 32 characters. SSID
is used to identify your own wireless router from others when
there are other wireless routers in the same area. The default
SSID is ‘airlink101’; it’s recommended to change it to a name
that you can identify, such as myhome, office_room1, etc.

19

Channel Width

Set channel width of wireless radio. Do not modify default value

if you don’t know what it is, default setting is ‘40 MHz’.

Control SideBand Select the Upper or Lower band for your Control Sideband.

While Upper band is selected, the channels you can select are
from channel 5 to channel 11. While Lower band is selected, the
channels you can select are from channel 1 to channel 7.

802.11n needs to use five continuous channels for high-speed
transmission.

Channel Number Select a channel from the dropdown list of ‘Channel Number’ for

broadcasting. You can choose any channel number you want to
use, and almost all wireless clients can locate the channel you’re
using automatically without any problem. However, it’s still useful
to remember the channel number you use, some wireless client
supports manual channel number selecting, and this would help
in certain scenario when there is some radio communication
problem.

Step 9 Select a desired Security Mode from the drop-down menu.

WPA2(AES) is the most secured encryption mode for general users. WEP is the most common
encryption but the least secured. It is recommended to use WPA2 (AES) for your wireless
security if all wireless devices on your network can support this mode.

WEP

20

Parameters Description

Key Length You can select the WEP key length for encryption, 64-bit

or 128-bit. Larger WEP key length will provide higher
level of security, but the throughput will be lower.

Key Format You may select ASCII Characters (alphanumeric format)

or Hexadecimal digits (in the "A-F", "a-f" and "0-9" range)
to be the WEP Key.

Key Setting The WEP key is used to encrypt data transmitted in the

wireless network. Fill the text box by following the rules
below.
64-bit WEP: input 10-digit Hex values (in the "A-F", "a-f"
and "0-9" range) or 5-digit ASCII character as the
encryption keys.

128-bit WEP: input 26-digit Hex values (in the "A-F", "a­f" and "0-9" range) or 13-digit ASCII characters as the
encryption keys.

Click on Finished to save and activate all the settings. Now, you can start to use the router as
your internet gateway.

21

WPA(TKIP)

Wi-Fi Protected Access (WPA) is an advanced security standard. You can use a pre-shared key
to authenticate wireless stations and encrypt data during communication. It uses TKIP to change
the encryption key frequently.

Parameters Description

Pre-shared Key Format You may select to select Passphrase (alphanumeric

format) or Hexadecimal Digits (in the “A-F”, “a-f” and “0­9” range) to be the Pre-shared Key. For example:
Passphrase: iamguest
Hexadecimal Digits: 12345abcde

Pre-shared Key The Pre-shared key is used to authenticate and encrypt

data transmitted in the wireless network. Fill the text box
by following the rules below.
Hex: input 8~64bit Hex key (in the “A-F”, “a-f” and “0-9”
range) for the pre-shared key.
Passphrase: input 8~63 characters for the pre-shared
key.

Clicking on OK to save and activate all the settings. Now, you can start to use the router as your
internet gateway.

22

WPA2(AES) / WPA2-Mixed

Select WPA2 (AES) for Security Mode, and enter a Pre-Shared Key between 8 to 63 characters
(alphanumeric, case sensitive).

Wi-Fi Protected Access 2(WPA2) is an advanced security standard. You can use a pre-shared
key to authenticate wireless stations and encrypt data during communication. It uses AES to
change the encryption key frequently. WPA2-mixed supports both WPA2 and WPA. It is a good
choice when some wireless devices on your network support WPA only.

Parameters Description

Pre-shared Key Format You may select Passphrase (alphanumeric format) or

Hexadecimal digits (in the “A-F”, “a-f” and “0-9” range) to
be the Pre-shared Key.

Pre-shared Key The Pre-shared key is used to authenticate and encrypt

data transmitted in the wireless network. Fill the text box
by following the rules below.
Hex: input 64-digit Hex values (in the “A-F”, “a-f” and “0­9” range) or at least 8 character pass phrase as the pre­shared keys.

Click on Finished to save and activate all the settings. Now, you can start to use the router as
your internet gateway.

Note: It is suggested to write down the security settings (Security Mode and Key ) y ou
configured for the Router on a piece of paper and keep it in a safe place.

23

Step 10 Click OK to finish the Setup Wizard. After your router restarts, you will go back to the

Status page with valid IP address assigned by you ISP or configured by yourself (i.e. Static IP).
Now you should be able to connect to the Internet.

If each field has a valid number assigned, the router is connected to the Internet.

2.4 Troubleshooting

If you have trouble connecting to the Internet, try the following steps.

Step 1 Power off the Cable/DSL modem, router, and computer and wait for 5 minutes.
Step 2 Turn on the Cable/DSL modem and wait for the lights on the modem to settle down.
Step 3 Turn on the router and wait for the lights on the router to settle down.
Step 4 Turn on the computer.
Step 5 Log in to the router and select the Status tab.
Step 6 Verify that the Internet IP Address, Subnet Mask, and Default Gateway have valid

numbers assigned to them (instead of all 0’s).

If each field has a valid number assigned, the router is connected to the Internet.
