SECURITY
This Gateway includes a number of options to help provide a secure connection to t he Next G™
Network.
Security features include:
•
WEP / WPA / WPA± data encryption
•
SPI Firewall
•
VPN Pass-Through
•
MAC address IP filtering
•
Aut hentication protocols – PAP / CHAP
You can aut henticate or encrypt your service on t he Wi-Fi Protected Access algorit hm, which
provides protection against unaut horized access such as eavesdropping.
The
following
screen
appears
when
Security
is
selected.
The
Security
page
allows
you
to
configure security features of your Gateway’s wireless LAN interface. You can set t he network
aut hentication met hod, select data encryption, specify whet her a network key is required to
aut henticate to t his wireless network and specify t he encryption strengt h.
Click Save/Apply to configure t he wireless security options.

Select SSID
Your
Service
Set
Identifier
(SSID),
sets
your
Wireless
Network
Name.
You
can
connect
multiple
devices
including
Laptops,
Desktop PCs and PDAs to your Wireless Gateway. To get additional
devices connected, scan for a network, and locate t he SSID shown
on your Wireless Security Card. If t he SSID does not match, access
is denied.
Network Aut hentication
This
option
is
used
for
aut hentication
to
t he
wireless
network.
Each
aut hentication
type
has
its
own
settings.
For
example,
selecting 80±.1X aut hentication will reveal t he RADIUS Server IP
address, Port and key fields.
WEP Encryption
This
option
indicates
whet her
data
sent
over
t he
network
is
encrypted. The same network key is used for data encryption and
network aut hentication. Whilst four network keys can be defined,
only one can be used at any one time.
Encryption Strengt h
This
drop-down
list
box
will
display
when
WEP
Encryption
is
enabled.
The
key
strengt h
is
proportional
to
t he
number
of
binary
bits
comprising
t he
key.
This
means
t hat
keys
wit h
a
greater number of bits have a greater degree of security and are
considerably more difficult to crack. Encryption strengt h can be
set to eit her 64 -bit or 1±8-bit. A 64 -bit key is equivalent to 5 ASCII
characters
or
10
hexadecimal
numbers.
A
1±8-bit
key
contains
13
ASCII
characters
or
±6
hexadecimal
numbers.
FYI:
Each
key
contains
a
±4 -bit
header
(an
initiation
vector)
which
enables
parallel decoding of multiple streams of encrypted data.

Band
The new amendment allows IEEE 80±.11g units to fall back to speeds of 11
Mbps, so IEEE 80±.11b and IEEE 80±.11g devices can coexist in t he same
network. The two standards apply to t he ±.4 GHz frequency band. IEEE
80±.11g creates data-rate parity at ±.4 GHz wit h t he IEEE 80±.11a standard,
which has a 54 Mbps rate at 5 GHz. (IEEE 80±.11a has ot her differences
compared to IEEE 80±.11b or g, such as offering more channels.)
Channel
Drop-down menu t hat allows selection of a specific channel.
Auto Channel
Timer (min)
Auto channel scan timer in minutes (0 to disable)
80±.11n/EWC
Wit h drop-down menu, “Auto” is for 11n and “Disable” is for 11g
Bandwidt h
Drop-down menu specifies t he following bandwidt h: ±0MHz and 40MHz.
Control
Sideband
This is available for 40MHz. Drop-down menu allows selecting upper
sideband or lower sideband
80±.11n Rate
Drop-down menu specifies t he following fixed rates. The maximum rate
for bandwidt h, ±0MHz, is 130MHz and t he maximum bandwidt h, 40MHz, is
±70MHz
80±.11n
Protection
It is similar as 80±.11g protection. In Auto mode t he router will use RTS/
CTS to improve 80±.11n performance in mixed 80±.11n/ 80±.11g/ 80±.11b
networks. Turn protection off to maximize 80±.11n t hroughput under most
conditions.
Support
80±.11n client
only
Drop-down menu allows selecting “On/O ff ”. Choosing “On” allows t he
client wit h 11n only to connect, not for 11g or 11b; choosing “O ff ” allows
t he client wit h 11n/11g/11b to connect
54g Rate
Drop-down menu t hat specifies t he following fixed rates: Auto: Default.
Uses t he 11 Mbps data rate when possible but drops to lower rates
when necessary.
1 Mbps, ±Mbps, 5.5Mbps, or 11Mbps fixed rates. The
appropriate setting is dependent on signal strengt h.
Multicast Rate
Setting multicast packet transmit rate.
Basic Rate
Setting basic transmit rate.
Fragmentation
Threshold
A t hreshold, specified in bytes, t hat determines whet her packets will be
fragmented and at what size.
On an 80±.11 WLAN, packets t hat exceed
t he fragmentation t hreshold are fragmented, i.e., split into, smaller
units suitable for t he circuit size.
Packets smaller t han t he specified
fragmentation t hreshold value are not fragmented.
Enter a value between
±56 and ±346. If you experience a high packet error rate, try to slightly
increase your Fragmentation Threshold. The value should remain at its
default setting of ±346.
Setting t he Fragmentation Threshold too low may
result in poor performance.
RTS Threshold
Request to Send, when set in bytes, specifies t he packet size beyond
which t he WLAN Card invokes its RTS/CTS mechanism.
Packets t hat
exceed t he specified RTS t hreshold trigger t he RTS/CTS mechanism. The
NIC transmits smaller packet wit hout using RTS/CTS. The default setting of
±347 (maximum lengt h) disables RTS Threshold.

Description
DTIM Interval
Delivery Traffic Indication Message (DTIM), also known as Beacon Rate.
The entry range is a value between 1 and 65535. A DTIM is a countdown
informing clients of t he next window for listening to broadcast and
multicast messages. When t he AP has buffered broadcast or multicast
messages for associated clients, it sends t he next DTIM wit h a DTIM
Interval value. AP Clients hear t he beacons and awaken to receive t he
broadcast and multicast messages. The default is 1.
Beacon
Interval
The amount of time between beacon transmissions.
Each beacon
transmission identifies t he presence of an access point.
By default, radio
NICs passively scan all RF channels and listen for beacons coming from
access points to find a suitable access point.
Before a station enters
power save mode, t he station needs t he beacon interval to know when
to wake up to receive t he beacon (and learn whet her t here are buffered
frames at t he access point). The entered value is represented in ms.
Default is 100. Acceptable entry range is 1 to 0xffff (65535)
Global Max
Clients
The device can support 4 SSID, and each SSID can set its own max clients,
but it can’t be bigger t han Global max clients. “Global Max Clients” limits
t he total associated clients of t he 4 SSID.
Xpress
TM
Technology
Xpress
TM
Technology is compliant wit h draft specifications of two planned
wireless industry standards.
Transmit
Power
The router will set different power output (by percentage) according to
t his selection.
