Once the WLN is authenticated, additional impacts include:
Roaming
A WLN configured for WPA-PSK can only roam to APs that have WPA-PSK enabled in
the same ESS.
A WLN configured for LEAP can only roam to APs that support LEAP, roaming, and are
connected to the same RADIUS server.
Data Throughput and Latency
Round trip latency may increase and overall throughput may decrease, due to the
additional steps to encrypt or decrypt data.
Re-Keying
The session key may expire and the authentication process will be executed again
causing streaming data to stop until a new key is authorized.
