When I click the network icon in the system tray and then right click on a wireless network on the "charm bar" or whatever it's called when it appears and the select "View Connection Properties" I get the "Wireless Network Properties" window where everything is disabled. There is also a box in that window saying "These settings are managed by your system administrator". Needless to say that I am an administrator.
I suspect that this can be configured via Policy Editor, but I can't find the right setting. I had a similar problem being unable to bridge network adapters which I successfully solved by changing a value in the Policy Editor.
Does anyone know how to make these properties changeable?
