MSG: this version does not include the web interface support for wi-fi. To manage the wireless devices you need to run the wi-fi manager script from the console by using a serial, VGA or ssh session.
That’s correct, for the moment you have to manage the wireless devices via console or remote ssh session.
I also tried to open the zeroshell by PUTTY ssh, but it is not working.
From ZeroShell WebGUI you have to enable SSH via Setup>SSH>Secure Shell Settings
Once you allow access to your client ip try to login via ssh where username=admin and password=ZeroShell webgui password
