Detecting WEP Encryption via new D-Bus API

[Phillip Nixon]

Hello,

I would like to know how to determine if a network is encrypted with
WEP via the new D-Bus API. Specifically, I would like to be able to
automatically prompt a user in a gui to enter the PSK if they want to
join a network from scan results that is WEP encrypted.

I see the "groups" property, but this appears to be the capabilities,
and not what the network is actually using.

Thank you.

Phillip
