RTS Threshold
RTS threshold is used to decide the time interval
between every RTS (Request to Send) packets.
Using a smaller value will cause the wireless
router to send RTS packets more often, and all
wireless stations will be able to recover from
collision (two stations send the packet at the same
time, which will destroy transmitted data packet)
more quickly.
However, sending RTS packets too often will
reduce the performance of wireless network, and
you should only use a smaller value when there’re
a lot of wireless stations connected to this wireless
router. It’s safe to use default value (2347) when
there are less then 10 wireless clients.
When you wish to decrease the RTS threshold
value to improve network performance and
stability, please decrease ‘Fragment
Threshold’ value also.
Beacon Interval
Beacon Interval is used to control the time interval
between every beacon packet. If you use a
smaller value, this wireless router will send the
beacon packet more often, and wireless clients
can found this wireless router quickly; If you use a
larger value, wireless clients will have to scan for
more times before it can find this wireless router.
By using a larger value, there will be lesser
beacon packets sent by this wireless router, and
the network performance will be better.
Data Rate
Please select the wireless data rate from
dropdown list. You can select a fixed data rate and
all wireless clients must use this data rate to
communicate with wireless router.
It’s recommended to select ‘Auto’ and let
wireless client / router to decide the
communication speed by actual radio
reception.

Preamble Type
Select the preamble type (long or short) for the
network packet. When you’re using this router in a
heavily-loaded network environment, select ‘Short
preamble’ will help to improve network
performance.
However, not every network client works with
short preamble (especially certain 802.11b
only wireless clients). If you found that some
wireless clients can’t connect to this router
when you select ‘Short Preamble’, please
select ‘Long Preamble’.
Broadcast SSID
By selecting ‘Enabled’ here, this router will
broadcast its SSID to all wireless clients so they
can connect to this router. However, there will be
some security risk to let everyone know this
router’s SSID.
By selecting ‘Disabled’ here, this router will not
broadcast its SSID, so only client who know this
router’s SSID is able to connect to this router, and
therefore security level is improved.
IAPP
IAPP stands for
Inter-Access Point Protocol
, If
your wireless clients will roam between access
points, you can select ‘Enabled’ here.
802.11g Protection
When this wireless router is working in 802.11B +
802.11G mode, it’s high recommended to enable
802.11g protection to prevent data collision, and
this will improve network stability and
performance.
WMM
Select ‘Enabled’ to enable support for WMM
(Wireless MultiMedia). This will improve the
performance of video / audio data transmission.

RF Output Power
Select the radio output power. If all wireless clients
are not far away from wireless router, you can
select a lower output power to save energy and
prevent other people to scan your wireless router
from distant.
Turbo Mode
Turbo Mode will increase the performance of
wireless data transmission . You can set this
option to ‘Always’ and this router will switch turbo
mode on infinitely, but some wireless clients which
are not compatible with Turbo Mode may not be
able to connect to this router. It’s recommended to
select ‘Auto’ to let this wireless router to switch
turbo mode on when wireless client supports it.
Currently, this function only works with Realtek
wireless network cards.

2-7-3 ‘Security’ Setting
You can set wireless security (data encryption) settings in this menu. When
data is encrypted, other people will not be able to read the contents of the data
you transmitted by wireless interface, so you can keep privacy. Also, when
encryption is enabled, only wireless client with correct encryption key will be
able to connect to this router, so unauthorized clients who do know correct
encryption key will not be able to connect to this router.
The descriptions of every setup item are listed below:
Item Name
Description
Encryption
Please select the encryption type from dropdown
list. For the requirements of the key of every kinds
of encryption, please refer to the descriptions at
the last of this chapter.
Set WEP Key
Set WEP key:
Key Length: There are two types of WEP key
length: 64-bit and 128-bit. Using ‘128-bit’ is safer
than ’64-bit’, but will reduce some data transfer
performance.
Key Format: There are two types of key format:
ASCII and Hex. When you select a key format, the
number of characters of key will be displayed. For
example, if you select ’64-bit’ as key length, and
Page 65 / 93
64
‘Hex’ as key format, you’ll see the message at the
right of ‘Key Format’ is ‘Hex (10 characters), which
means the length of WEP key is 10 characters.
Default Tx Key: You can set up to four sets of
WEP key, and you can decide which key is being
used by default here. If you don’t know which one
you should use, select ‘Key 1’.
Encryption Key 1 to 4: Input WEP key characters
here, the number of characters must be the same
as the number displayed at ‘Key Format’ field. You
can use any alphanumerical characters (0-9, a-z,
and A-Z) if you select ‘ASCII’ key format, and if
you select ‘Hex’ as key format, you can use
characters 0-9, a-f, and A-F. You must enter at
least one encryption key here, and if you entered
multiple WEP keys, they should not be same with
each other.
When you finish, click ‘Apply’ button to save
changes; click ‘Close’ to close WEP key setup
window, or click ‘Reset’ to clear the content of
every field in this page.
Use 802.1x
Authentication
Check this box to use 802.1x authentication
instead of local WEP key. You also have to select
the length of WEP key (64bits or 128bits), and
setup the IP address and login information of
RADIUS authentication server below.
This option works with WEP encryption only.
WPA Authentication
Mode
Select the type of WPA authentication (Enterprise /
Using RADIUS sever) or PSK (Pre-shared key). If
you don’t have RADIUS authentication server,
please select PSK.
This option works with WPA encryption only.
