VAP
VAP0 is the physical wireless radio interface. To disable
VAP0, you must disable the wireless radio. Due to the
dependency of the WDS links with the VAP0 security mode,
VAP0 cannot be configured to None, Static WEP, or 802. 1 X if
the WDS links have WPA Personal as the security mode. If
you need to change the security of VAP0 from WPA Personal
or WPA Enterprise to None, Static WEP, or 802. 1 X, then
remove the WPA security mode for all the WDS links.
