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 EMG2926-Q10A 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.

Check this field to allow wireless devices using

WPA-PSK

security mode to connect to

your EMG2926-Q10A.

The

Group Key Update Timer

is the rate at which the AP sends a new group key out to

all clients.

WPA Compatible

This check box is available only when you select

Select the check box to have both WPA2 and WPA wireless clients be able to

communicate with the EMG2926-Q10A even when the EMG2926-Q10A 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.

More AP Screen

This screen allows you to enable and configure multiple wireless networks and guest wireless

network settings on the EMG2926-Q10A.

You can configure up to four SSIDs to enable multiple BSSs (Basic Service Sets) on the EMG2926-

Q10A. 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.

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 EMG2926-Q10A.

The key must be the same on the external authentication server and your EMG2926-

Q10A. The key is not sent over the network.

Session Timeout

The EMG2926-Q10A 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.

#

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 EMG2926-Q10A’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.
