Hi,
I\'m not an expert so I may be on the wrong track...
If you simply want to establish a connection through a wireless card in the Z then you may not need OpenVPN. On the Z you can set up a wireless network connection (somewhere in settings?). I think you don\'t have to manually change anything (Infrastructure mode, WEP settings, etc.) in the settings. The Z will pick up the settings from the host. I think after setting up the network connection an icon appears in the taskbar and you can activate the connection through that.
I am on tkcROM 1.0, I have a wireless card installed in my WinXP PC and a D-Link 660W in my Z5500. I can tell you exactly how to set it all up on this configuration but you may need help from someone more knowledgeable if the above doesn\'t work on your config.
