There is absolutely no way to change the layout of that dialog. As it doesn't support custom sorting and resizing, you can't change that.
But the source for this list is accessible from the following file:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
You can open/read the file in any text editor, Property List Editor/Xcode 4, PlistBuddy
or defaults
.
To get the full list of networks:
defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences RememberedNetworks | grep SSIDString | cut -d= -f2 | cut -d';' -f1
To also sort the list of network names case-insensitively:
defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences RememberedNetworks | grep SSIDString | cut -d= -f2 | cut -d';' -f1 | sort -f
To print both the network name and the security type (like in the list), use:
defaults read /Library/Preferences/SystemConfiguration/com.apple.airport.preferences RememberedNetworks | grep -E "(SSIDString|SecurityType)" | cut -d= -f2 | sed -e 'N;s/\n/ /' -e 's|;||g'
