Examples: iwconfig ethX <mode> mode: Managed (Infrastructure Station mode) Ah-hoc (Ad hoc mode) Master (Access Point mode) channel: Set the channel in the device. Example: iwconfig ethX channel <channel> The channel can vary from 1 to 14.

  • Page 9 After make process completed, A executable file wpa_supplicant created. To create a WPA PSK connection, please modify the configuration file (For detailed description , you can refer to the original sample configuration file: wpa_supplicant.conf) wpa_supplicant_psk.conf to meet wpa-psk test condition. Sample settings for wpa-psk: network={ ssid="wrt55ag"...

If the zd1211 is not open yet, please open it firstly by command: ]$ ifconfig eth1 up <IP address of the network interface> After network interface is opened, enter the command to build wpa psk connection: ]$ ./wpa_supplicant -ieth1 -c wpa_supplicant_psk.conf -d -D zydas...
  • Page 11 solution on the network. Appendix: How to create certificate file and private key file. 1. First, please install a personal certificate via a web browser (IE 6.0 or later) to a Radius server (Windows 2003 Server or Windows 2000 Server edition). 2.
