The Router also operates as a wireless Access Point (AP), allowing wireless
computers to communicate with each other. To configure this function, all you
need to do is to enable the wireless function, define the
radio channel
, the
SSID
and the
security options
.
Select the
Enable
radio button, then select the country from the drop down
menu, and click on
SAVE SETTINGS
button. In
Figure 1 the
WIRELESS
main
screen is shown: in left-hand side list of command inside this section does ap-

WIRELESS >> CHANNEL
AND SSID
It is necessary to specify a
common radio channel
and
ESSID
to be used by the
Router and by all of its wireless clients (see
Figure 2). Be sure to configure all
connected clients with the same values.

WIRELESS >> ACCESS
CONTROL
By using the Access Control functionality, it is possible to restrict access on
MAC address base. Each PC has a unique identifier known as a
Medium Ac-
cess Control (MAC) address
. With MAC filtering enabled, the computers whose
MAC address are listed in the filtering table, will be able to connect (or will be
denied access) to the Router. In
Figure 3
WLAN Access Filtering Table
is
shown.

You can enter up to 32 addresses here in the table. Click Add cur-
rently MAC stations button to quickly copy the entry to the MAC
Filtering table.
WIRELESS >> SECURITY
To make the wireless networks safer, the security function should be turned on.
In
Figure 4 the panel where it is possible to set security is shown. The Router
supports
WEP (Wired Equivalent Privacy
) and
WPA (Wi-Fi Protected)
security
mechanisms.
FIGURE 4
WIRELESS SECURITY SETTINGS
The following options are available:
No WEP, No WPA
WEP only
WPA only
By selecting the “No WEP, no WPA” option,
any client with the correct SSID will be allowed to connect
to this Router. We suggest to turn on the security function to protect wireless communication.
WIRELESS >> SECURITY
>> WEP
Figure 5 shows the
WEP
configuration panel. To use
WEP
to protect the wire-
less network, it is necessary to set the same parameters for the Router and for
all the wireless clients.

DESCRIPTION
WEP Mode
Select 64 bit or 128 bit key to use for encryption
Key Entry Method
Select Hex or ASCII. ASCII is selected, the Passphrase
checkbox will not available
Key Provisioning
Select Static or Dynamic. If you choose Dynamic, then you
should also set up the 802.1X function
Static WEP Key Settings
Default Key ID
From 1-4 characters
Passphrase
Two ways to generate the encryption keys, with our without
the passphrase function.
To generate encryption keys using the passphrase function,
check the Passphrase box, and enter the string. Note that the
passphrase can consist of up to 32 alphanumeric characters.
To generate encryption keys without using the passphrase
function, make your selections in WEP Mode and Key Entry
Method, then encryption keys would be generated automati-
cally. It is also possible to manually enter the encryption keys.
Do enter five hexadecimal pairs of digits for the 64-bit WEP
mode, or enter 13 pairs for the 128-bit WEP Mode. Note that a
hexadecimal digit is a number or letter in the range 0-9 of A-F
Before saving settings the key is shown in clear text. If your wireless client does not have a passphrase
utility make a note of the default key before saving settings. This is so you can configure your wireless
client with the proper SSID to connect to this Router.
We suggest you to turn on the security function to protect your wireless communication.
