The download is included in the command line so just copy paste once at time, download software like putty write IP of your Zyxel, then connect and then you can use commands

Thank you very much for your reply!
I have downloaded putty,cd to temp but when I m trying to get the firmware I get the error
Failed to send request,operation not permitted

download the fw to your client, then (win)scp it to the WSM.

sounds to me you've set it up as a dumb AP.
