This screen allows you to enable and configure multiple guest wireless network settings on the EMG3435-
Q20A.
You can configure up to four SSIDs to enable multiple BSSs (Basic Service Sets) on the EMG3435-Q20A.
This allows you to use one access point to provide several BSSs simultaneously. You can then assign
varying security types to different SSIDs. Wireless clients can use different SSIDs to associate with the
same access point.

Pre-Authentication This field is available only when you select WPA2.

connecting to it. Select Ena b le to turn on preauthentication in WAP2. Otherwise, select
Disa b le .
Authentication Server
IP Address Enter the IP address of the external authentication server in dotted decimal notation.
Port Number Enter the port number of the external authentication server.
You need not change this value unless your network administrator instructs you to do so
with additional information.
Shared Secret Enter a password (up to 127 alphanumeric characters) as the key to be shared between
the external authentication server and the EMG3435-Q20A.
The key must be the same on the external authentication server and your EMG3435-Q20A.
The key is not sent over the network.
Session Timeout The EMG3435-Q20A automatically disconnects a wireless client from the wireless and wired
networks after a period of inactivity. The wireless client needs to send the username and
password again before it can use the wireless and wired networks again. Some wireless
clients may prompt users for a username and password; other clients may use saved login
credentials. In either case, there is usually a short delay while the wireless client logs in to
the wireless network again.
Enter the time in seconds from 0 to 999999.
Apply Click Ap ply to save your changes back to the EMG3435-Q20A.
