• Access Point 802.1x Authentication to Network—802.1x can also be enabled on
the ethernet port of the switch that the access point's ethernet cable is plugged into.
Having 802.1x enabled on the switch prevents any device that is not able to
successfully authenticate from being able to use the ethernet port. This option is
useful if your access point is located in an insecure location, and you want to
prevent someone who plugs a computer or another access point into the network
connection being used by your access point from being able to access the network.
This feature defaults to being disabled.
If "MD5 Authentication to Network with MAC Address" is selected, the access
point's MAC address will be used for both the username and password. For
example, an access point with the MAC Address 12-34-56-78-9A-BC would use a
username and password of "123456789abc".
If "MD5 Authentication to Network with Supplied Username and Password" is
selected, the access point with authenticate using the username and password
supplied. If you press the "Apply" button when no password is specified, the
previous password will continue to be the one used. You must enter the same
password twice to successfully change the password.
