Warning to users of Asus firmware:

In the Administration > Firmware Upgrade tab, never rely on their [Check] version button. It's consistently inaccurate. It's a long-known (and serious) flaw that's been like this since day one of these products and still to this day. It'll happily report, "The router's current firmware is the latest version.", even if it's months behind in vulnerability fixes. Go to Asus' site for the latest firmware then use the upload option to upgrade. Or, probably better yet, don't use their firmware.
