Wireless LAN Configuration 

To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point 
must use the same settings, as follows: 

Mode 

On client Wireless Stations, the mode must be set to "Infrastructure". 
(The Access Point is always in "Infrastructure" mode.) 

SSID (ESSID) 

Wireless Stations should use the same SSID (ESSID) as the Access 
Point they wish to connect to. Alternatively, the SSID can be set to "any" 
or null (blank) to allow connection to any Access Point. 

Security 

The Wireless Stations and the Access Point must use the same settings 
for Wireless security (Disabled, WEP, WPA-PSK, WPA2-PSK, WPA 
8021.x, WPA2 802.1x, WEP 802.1x) 

• 

If Wireless security remains disabled on the Access Point, all 
stations must have wireless security disabled. 

• 

If Wireless security is enabled on the Access Point, each station 
must use the same settings.
