DESCRIPTION

Security Mode

Select

WPA2-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 NBG6817.

PMF

Protected Management Frames (PMF) is a protection mechanism of action management

frames.

Check this field to allow wireless devices using the PMF protection mechanism to

connect to your NBG6817.

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).

Security Mode

Select

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 NBG6817 even when the NBG6817 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.

Guest Wireless Screen

This screen allows you to enable and configure multiple guest wireless network settings on the

NBG6817.

You can configure up to four SSIDs to enable multiple BSSs (Basic Service Sets) on the NBG6817.

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

Expert Mode

> Wireless > Guest Wireless

. The following screen displays.

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.

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 NBG6817.

The key must be the same on the external authentication server and your NBG6817.

The key is not sent over the network.

Session Timeout

The NBG6817 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.

Guest Wireless Edit

Use this screen to edit an SSID profile. Click the

Edit

icon next to an SSID in the

Guest Wireless

screen. The following screen displays.

Table 31

Expert Mode > Wireless > Guest Wireless

LABEL

DESCRIPTION

Band

Use

2.4GHz

or

5GHz

to set up the NBG6817’s guest Wi-Fi network.

#

This is the index number of each SSID profile.

Status

This shows whether the SSID profile is active (a yellow bulb) or not (a gray bulb).

SSID

An SSID profile is the set of parameters relating to one of the NBG6817’s BSSs. The SSID

(Service Set IDentifier) identifies the Service Set with which a wireless device is associated.

This field displays the name of the wireless profile on the network. When a wireless client

scans for an AP to associate with, this is the name that is broadcast and seen in the

wireless client utility.

Security

This field indicates the security mode of the SSID profile.

Remaining time

If the user is currently not permitted to access the Internet, you can click

Set

to allow

access for a specified period of time. A screen then displays allowing you to set how long

(in hours) the user is allowed to access the Internet.

This field displays the amount of Internet access time that remains for each user before the

NBG6817 blocks the user from accessing the Internet.

0:0:0

means there is no extra Internet access time.

Edit

Click the

Edit

icon to configure the SSID profile.

Expert Mode > Wireless > Guest Wireless > Guest Wireless Setup: Edit

LABEL

DESCRIPTION

Active

Select this to activate the SSID profile.

Name (SSID)

The SSID (Service Set IDentity) identifies the Service Set with which a wireless client is

associated. Enter a descriptive name (up to 32 printable characters found on a typical

English language keyboard) for the wireless LAN.

Hide SSID

Select this check box to hide the SSID in the outgoing beacon frame so a station cannot

obtain the SSID through scanning using a site survey tool.

Intra-BSS Traffic

Blocking

A Basic Service Set (BSS) exists when all communications between wireless clients or

between a wireless client and a wired network client go through one access point (AP).

Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled,

wireless clients can access the wired network and communicate with each other. When

Intra-BSS is disabled, wireless clients can still access the wired network but cannot

communicate with each other.

WMM QoS

Check this to have the NBG6817 automatically give a service a priority level according to

the ToS value in the IP header of packets it sends.

WMM QoS (Wifi MultiMedia Quality of Service) gives high priority to voice and video, which

makes them run more smoothly.

Enable

Bandwidth

Management for

Guest WLAN

Select this to turn on bandwidth management for the Guest Wi-Fi network.

Maximum

Bandwidth

Enter a number to specify maximum bandwidth the Guest Wi-Fi network can use.

Security Mode

Select

WPA-PSK

or

WPA2-PSK

to add security on this wireless network. The wireless

clients which want to associate to this network must have same wireless security settings

as this device. After you select to use a security, additional options appears in this screen.

See

Section 11.3 on page 99

for detailed information on different security modes. Or you

can select

No Security

to allow any client to associate this network without authentication.

Note: If the WPS function is enabled (default), only

No Security

and

WPA2-PSK

are

available in this field.
