known to be already authenticated, so it proceeds directly to key exchange 
and association.

• To support pre-authentication, both clients and access points in the network 

must be WPA2 enabled.

• Pre-authentication requires all access points in the network to be on the 

same IP subnet.

The access point provides a link integrity feature that can be used to ensure that 
wireless clients are connected to resources on the wired network. The access point 
does this by periodically sending Ping messages to a host device in the wired 
Ethernet network. If the access point detects that the connection to the host has 
failed, it disables the radio interfaces, forcing clients to find and associate with 
another access point. When the connection to the host is restored, the access point 
re-enables the radio interfaces.
