I must confess, that I cheated a little, as the configuration was initially created with
nm-connection-editorby selecting the 'Available to all users' option. Copying the configuration files to the Fedora 17 rootfs image made my wireless work immediately.
The configuration consists out of two files:
MyWLANis just a name for your connection
ESSID="MyESSID"Of course it is needed to change at least the
KEY_MGMTcan probably have other values, but there is no need for me to research that atm.
WPA_PSK="My Top Secret Password"This password will likely not work anywhere, just change it to whatever is needed.
After putting these two files in place (copied from an other device after booting) made NetworkManager connect to the WLAN immediately.
Some tools for checking the connection are:
nm-toolwhich displays the detected networks and some more details.
nmcli con up MyWLANin case you want to force connecting to the WLAN configured under
