Management 3
This chapter explains how to use your Web Browser to configure the Wireless Print Server.
Overview
The Wireless Print Server incorporates the HTTP server. This allows you to connect to the Wireless Print Server and configure it using
your Web Browser. Most browsers should work, provided they support tables and forms.
Preparation
Because it supports dynamic IP Address allocation using DHCP or BOOTP, the Wireless Print Server ships with an IP Address of
0.0.0.0.
This is NOT a valid IP Address.
Therefore, you must do ONE of the following:
•Check your DHCP server (if you have one), and determine the IP Address allocated to the Wireless Print Server.
•Use the Diagnostic Button (if fitted) to print a report which includes the current IP address. (Press the Diagnostic Button, and
hold it for 2 seconds.)
•Use the Setup Wizard or another Wireless Print Server utility to allocate a valid IP Address to the Wireless Print Server.
Connecting to the Wireless Print Server
1. Start your Web Browser.
2. In the Address box, enter HTTP:// followed by the IP Address of the Wireless Print Server.
e.g. http://192.168.0.100
3. You will then be prompted for the password. If no password has been set, just press ENTER.
4. Use the menu bar to move from one screen to another. Remember to save each screen before changing to a different screen.

Wireless Security Screen
There are 4 options for Wireless security:

Page 15
•Disabled - no data encryption is used.
•WEP - data is encrypted using the WEP standard.
•WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better
security than WEP. Use this if possible.
•WPA2-PSK - this is a further development of WPA-PSK, and offers even greater security.
Wireless Security - WEP
If "WEP" is selected, the screen will look like the following example.
Figure 13: WEP Screen
Security
System WEP
The 802.11b standard. Data is encrypted before transmission, but
the encryption system is not very strong.
Authentication Select the appropriate value, as used on your Wireless LAN -
"Open System" or "Shared Key."
Key Size Select the WEP Encryption level:
•64-bit (sometimes called 40-bit) encryption
•128-bit encryption (sometimes called 104 bit encryption)
This selection also allows you to choose the input type for the
keys - Hex or ASCII.
Keys •Use the radio buttons to select the default key.
•Enter the key value(s) you wish to use. Other stations must
have the same key values.
•Keys can be entered in Hex or ASCII, according to your Key
Size selection. Hex characters are the digits (0 ~ 9) and the
letters A ~ F.
Passphrase Enter some printable characters in the Passphrase field and click
the "Generate Keys" button to automatically configure the WEP
Key(s). For 64 bit keys, four keys fields will be generated. For
