WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via
radio using either a 64-bit or 128-bit key. Usually access point will preset a set of four keys
and it will communicate with each station using only one out of the four keys.
WPA (Wi-Fi Protected Access), the most dominating security mechanism in industry, is
separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK),
and WPA-Enterprise or called WPA/802.1x.
In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA
applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies
AES. The WPA-Enterprise combines not only encryption but also authentication.
Since WEP has been proved vulnerable, you may consider using WPA for the most secure
connection. You should select the appropriate security mechanism according to your needs.
No matter which security suite you select, they all will enhance the over-the-air data
protection and /or privacy on your wireless network. The Vigor wireless router is very
flexible and can support multiple secure connections with both WEP and WPA at the same
time.
Separate the Wireless and the Wired LAN- WLAN Isolation
enables you to isolate your
wireless LAN from wired LAN for either quarantine or limit access reasons. To isolate
means neither of the parties can access each other. To elaborate an example for business use,
you may set up a wireless LAN for visitors only so they can connect to Internet without
hassle of the confidential information leakage. For a more flexible deployment, you may add
filters of MAC addresses to isolate users’ access from wired LAN.
Manage Wireless Stations - Station List
will display all the station in your wireless
network and the status of their connection.
Below shows the menu items for Wireless LAN.

3.13.2 General Setup
By clicking the
General Settings
, a new web page will appear so that you could configure
the SSID and the wireless channel. Please refer to the following figure for more information.
Enable Wireless LAN
Check the box to enable wireless function.
Mode
At present, the router can connect to Mixed (11b+11g),
11g Only, 11b Only, Mixed (11g+11n), 11n Only and
Mixed (11b+11g+11n) stations simultaneously. Simply
choose Mix (11b+11g+11n) mode.
Index(1-15)
Set the wireless LAN to work at certain time interval
only. You may choose up to 4 schedules out of the 15
schedules pre-defined in
Applications >> Schedule
setup. The default setting of this filed is blank and the
function will always work.
Hide SSID
Check it to prevent from wireless sniffing and make it
harder for unauthorized clients or STAs to join your

wireless LAN. Depending on the wireless utility, the user
may only see the information except SSID or just cannot
see any thing about Vigor wireless router while site
surveying. The system allows you to set four sets of
SSID for different usage. In default, the first set of SSID
will be enabled. You can hide it for your necessity.
SSID
Means the identification of the wireless LAN. SSID can
be any text numbers or various special characters. The
default SSID is "DrayTek". We suggest you to change it.
Isolate
LAN
– Check this box to make the wireless clients
(stations) with the same SSID cannot access wired
PCs on LAN.
Member
–Check this box to make the wireless
clients (stations) with the same SSID not accessing
for each other.
Channel
Means the channel of frequency of the wireless LAN.
The default channel is 6. You may switch channel if the
selected channel is under serious interference. If you have
no idea of choosing the frequency, please select Auto to
let system determine for you.
Long Preamble
This option is to define the length of the sync field in an
802.11 packet. Most modern wireless network uses short
preamble with 56 bit sync filed instead of long preamble
with 128 bit sync field. However, some original 11b
wireless network devices only support long preamble.
Check it to use
Long Preamble
if needed to
communicate with this kind of devices.
Packet-OVERDRIVE
This feature can enhance the performance in data
transmission about 40%* more (by checking
Tx Burs
t).
It is active only when both sides of Access Point and
Station (in wireless client) invoke this function at the
same time. That is, the wireless client must support this
feature and invoke the function, too.
Note:
Vigor N61 wireless adapter supports this function.
Therefore, you can use and install it into your PC for
matching with Packet-OVERDRIVE (refer to the
following picture of Vigor N61 wireless utility window,
choose
Enable
for activating TxBurst).

Note:
* means the real transmission rate depends on the
environment of the network.
3.13.3 Security
This page allows you to set security with different modes for SSID 1, 2, 3 and 4 respectively.
After configuring the correct settings, please click
OK
to save and invoke it.
By clicking the
Security Settings
, a new web page will appear so that you could configure
the settings of WEP and WPA.

Mode
There are several modes provided for you to choose.
Disable
- Turn off the encryption mechanism.
WEP-
Accepts only WEP clients and the encryption key should
be entered in WEP Key.
WEP/802.1x Only -
Accepts only WEP clients and the
encryption key is obtained dynamically from RADIUS server
with 802.1X protocol.
WPA/802.1x Only-
Accepts only WPA clients and the
encryption key is obtained dynamically from RADIUS server
with 802.1X protocol.
