You are definitely not mistaken: after setup last year, we disabled the automatic approval. Since upgrading to the latest firmware on friday, the feature is enabled again, and grayed out.
From a security point of view, it's bad that someone can plug in an AP and it just joins the AP to your network without any approval requests...
Is there a workaround for this issue?
Michael Brado: I'm not sure if you're not talking about the automatic upgrade of firmwares? Unless I'm mistaken, what Jeff, Daniel (and I) mean is the automatic approval of new access points on your network.
