In other words when configuring an infrastructure network the user can make communication with the AP which he she wants to communicate with by setting the SSID of the desired AP in ezTCP See 3 1 2 For information about SSID of the AP AP manual or AP configuration program can be referred to If the user did not set the SSID the ezTCP will be connected with the AP that is first found when power is supplied The maximum length of the SSID is 32 bytes and the user can use ASCII code to set the SSID 4 2 2 Channel The channel is communication path in the network that it belongs to Channel values are set as the same value with the AP ET 4 2 3 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 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 4 3 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 s
