I'm debugging this remotely with a non-technical user and don't know exactly what form of security is present, only that the network has a key that is used when connecting other devices. I might have written this off as user confusion if this wasn't the second case of a user swearing their network needs a key but the scan looking similar.
Am I missing something here I could use to detect that a key is required? I've seen RSN
, WPA
or Privacy
on every other network with a key.
RSN
orWPA
then the network is not using any cypher, it is running unencrypted.
