Wired Equivalent Privacy (WEP)   

This is about security of the wireless LAN.   The wireless LAN provides similar security 

to that  of the  wired  LAN using  the WEP.   To  use  the  WEP,  the  user  must  set  the  key 

value.   According  to  the  key  value,  data  is  encoded  in  64  bits  or  128  bits  for 

communication.   If the user did not set the WEP, security-related problems may occur.  

There are two kinds of infrastructure network for WEP – Open System and Shared Key. 

User has to check the type when the network uses WEP.

How To configure wireless LAN 

Wireless LAN-related parameters can be configured through ezSerialConfig program. 

To  utilize  ezSerialConfig  program,  apply  power  with  no  LAN  card  inserted  and 

operate EZL-80c in serial configuration mode. 

With this program you can configure IP address and serial port-related parameters as 

well as wireless LAN parameters. 

 

 

 

Operate  EZL-80c  in  serial  configuration  mode  to  utilize  ezSerialConfig.  Follow  the 

sequence as described below. 

 

1.

 

Run ezSerialConfig program in the PC. 

2.

 

With no LAN card inserted, connect EZL-80c and the PC by a serial cable and apply 

power.
