Security
This Access Point provides complete wireless LAN security functions,
included are WEP, IEEE 802.1x, IEEE 802.1x with WEP, WPA with pre-shared
key and WPA with RADIUS. With these security functions, you can prevent your
wireless LAN from illegal access. Please make sure your wireless stations use
the same security function, and are setup with the same security key.
ESSID Selection:
This broadband router support multiple ESSID, you could
select and set up the wanted ESSID.
Broadcast ESSID:
If you enabled “Broadcast ESSID”, every wireless station
located within the coverage of this AP can discover this
AP easily. If you are building a public wireless network,
enabling
this
feature
is
recommended.
Disabling
“Broadcast ESSID” can provide better security.
WMM:
Wi-Fi MultiMedia if enabled supports QoS for experiencing better
audio, video and voice in applications.
Encryption:
When you choose to disable encryption, it is very insecure to
operate ESR-9752.

Enable 802.1x Authentication
IEEE 802.1x is an authentication protocol. Every user must use a valid account
to login to this Access Point before accessing the wireless LAN. The
authentication is processed by a RADIUS server. This mode only authenticates
users by IEEE 802.1x, but it does not encrypt the data during communication.
WEP Encryption
When you select 64-bit or 128-bit WEP key, you have to enter WEP keys to
encrypt data. You can generate the key by yourself and enter it. You can enter
four WEP keys and select one of them as a default key. Then AP can receive
any packet encrypted by one of the four keys.

Authentication Type:
There are two authentication types:
"Open System"
and
"Shared Key"
. Both AP and wireless client must be
configured with the same authentication type.
Key Length:
You can select the WEP key length for encryption, 64-bit or 128-bit.
The larger the key will be the higher level of security is used, but
the throughput will be lower.
Key Type:
You may select ASCII Characters (alphanumeric format) or
Hexadecimal Digits (in the "A-F", "a-f" and "0-9" range) to be the
WEP Key.
Default Key:
It’s the key used to encrypt data.
Key1 - Key4:
The WEP keys are used to encrypt data transmitted in the wireless
network. Use the following rules to setup a WEP key on the device.
64-bit WEP:
input 10-digits Hex values (in the "A-F", "a-f" and "0-9" range)
or 5-digit ASCII character as the encryption keys.
128-bit WEP:
input 26-digit Hex values (in the "A-F", "a-f" and "0-9" range)
or 13-digit ASCII characters as the encryption keys.

WPA Pre-Shared Key Encryption
Wi-Fi Protected Access (WPA) is an advanced security standard. You can use
a pre-shared key to authenticate wireless stations and encrypt data during
communication. It uses TKIP or CCMP (AES) to change the encryption key
frequently. So the encryption key is not easy to be cracked by hackers. This is
the best security available.

WPA-Radius Encryption
Wi-Fi Protected Access (
WPA
) is an advanced security standard. You can use
an external RADIUS server to authenticate wireless stations and provide the
session key to encrypt data during communication.
It uses
TKIP
or CCMP (
AES
) to change the encryption key frequently. Press
<Apply>
button when you are done.

- MAC Address Filtering
This wireless router supports MAC Address Control, which prevents
unauthorized clients from accessing your wireless network.
Enable wireless access control:
Enable the wireless access control function
Adding an address into the list
Enter the "MAC Address" and "Description" of the wireless station to be
added and then click
<Add>
. The wireless station will now be added into
the "MAC Address Filtering Table" below. If you are having any difficulties
filling in the fields, just click "Reset" and both "MAC Address" and
"Description" fields will be cleared.
Remove an address from the list
If you want to remove a MAC address from the "MAC Address Filtering
Table", select the MAC address that you want to remove in the list and
then click "Delete Selected". If you want to remove all the MAC addresses
from the list, just click the
<Delete All>
button. Click
<Reset>
will clear
your current selections.
Click
<Apply>
at the bottom of the screen to save the above configurations.
