LABEL
DESCRIPTION
Security Mode
Select
Static WEP
to enable data encryption.
PassPhrase
Enter a Passphrase (up to 26 printable characters) and click
Generate
.
A passphrase functions like a password. In WEP security mode, it is further converted by
the NBG6716 into a complicated string that is referred to as the “key”. This key is
requested from all devices wishing to connect to a wireless network.
WEP Encryption
Select
64-bits
or
128-bits
.
This dictates the length of the security key that the network is going to use.
Authentication
Method
Select
Auto
or
Shared Key
from the drop-down list box.
This field specifies whether the wireless clients have to provide the WEP key to login to
the wireless client. Keep this setting at
Auto
unless you want to force a key verification
before communication between the wireless client and the NBG6716 occurs.
Select
Shared Key
to force the clients to provide the WEP key prior to communication.

ASCII
Select this option in order to enter ASCII characters as WEP key.
Hex
Select this option in order to enter hexadecimal characters as a WEP key.
The preceding "0x", that identifies a hexadecimal key, is entered automatically.
Key 1 to Key 4
The WEP keys are used to encrypt data. Both the NBG6716 and the wireless stations
must use the same WEP key for data transmission.
If you chose
64-bits
, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose
128-bits
, then enter 13 ASCII characters or 26 hexadecimal characters ("0-
9", "A-F").
You must configure at least one key, only one key can be activated at any one time. The
default key is key 1.

Security Mode
Select
WPA-PSK

to enable data encryption.
WPA-PSK
Compatible
This field appears when you choose
WPA2-PSK
as the
Security Mode
.
Check this field to allow wireless devices using
WPA-PSK
security mode to connect to
your NBG6716.
Pre-Shared Key
WPA-PSK/WPA2-PSK
uses a simple common password for authentication.
Type a pre-shared key from 8 to 63 case-sensitive keyboard characters.
Group Key Update
Timer
The
Group Key Update Timer
is the rate at which the AP sends a new group key out to
all clients.
The default is
3600
seconds (60 minutes).

LABEL
DESCRIPTION
Security Mode
Select
WPA
or
WPA2
to enable data encryption.
WPA Compatible
This check box is available only when you select
WPA2-PSK
or
WPA2
in the
Security
Mode
field.
Select the check box to have both WPA2 and WPA wireless clients be able to
communicate with the NBG6716 even when the NBG6716 is using WPA2-PSK or WPA2.
Group Key Update
Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA-PSK/
WPA2-PSK
key management) or RADIUS
server (if using
WPA/WPA2
key
management) sends a new group key out to all clients. The re-keying process is the
WPA/WPA2 equivalent of automatically changing the WEP 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
WPA-PSK/WPA2-PSK
mode.
PMK Cache Period
This field is available only when you select
WPA2
.
Specify how often wireless clients have to resend usernames and passwords in order
to stay connected. Enter a time interval between 10 and 999999 minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.

More AP Screen
This screen allows you to enable and configure multiple wireless networks and guest wireless
network settings on the NBG6716.
You can configure up to four SSIDs to enable multiple BSSs (Basic Service Sets) on the NBG6716.
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.
Click
Network > Wireless LAN 2.4G/5G > More AP
. The following screen displays.
Pre-Authentication
This field is available only when you select
WPA2
.
Pre-authentication enables fast roaming by allowing the wireless client (already
connecting to an AP) to perform IEEE 802.1x authentication with another AP before
connecting to it. Select
Enable
to turn on preauthentication in WAP2. Otherwise,
select
Disable
.
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 NBG6716.
The key must be the same on the external authentication server and your NBG6716.
The key is not sent over the network.
Session Timeout
The NBG6716 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.
