Security Mode | Choose WPA2 or |
|
|
ReAuthentication | Specify how often wireless stations have to resend usernames and |
Timer | passwords in order to stay connected. |
| The default value is 0, which means the reauthentication off. |
| Note: If wireless station authentication is done using a RADIUS |
| server, the reauthentication timer on the RADIUS server |
| has priority. |
|
|
Idle Timeout | The NWA automatically disconnects a wireless station from the wired |
| network after a period of inactivity. The wireless station needs to |
| enter the username and password again before access to the wired |
| network is allowed. |
| The default time interval is 3600 seconds (or 1 hour). |
|
|
Group Key | The Group Key Update Timer is the rate at which the AP sends a |
Update Timer | new group key out to all clients. The |
| equivalent of automatically changing the group key for an AP and all |
| stations in a WLAN on a periodic basis. Setting of the Group Key |
| Update Timer is also supported in |
| default is 1800 seconds (30 minutes). |
|
|
PMK Cache | When a wireless client moves from one AP’s coverage area to |
| another, it performs an authentication procedure (exchanging |
| security information) with the new AP. Instead of |
| client each time it returns to the AP’s coverage area, which can cause |
| delays to |
| (or “cache”) and use information about their previous authentication. |
| Select Enable to allow PMK caching, or Disable to switch this |
| feature off. |
|
|
Pre- | |
Authentication | with a different AP from the one to which it is currently connected, |
| before moving into the new AP’s coverage area. This speeds up |
| roaming. Select Enable to allow |
| switch it off. |
