Their share the same interface and functions, and they can both be accessed through web
browsers. The only difference is HTTPS data are encrypted for extra security. Therefore,
we will discuss them together as “Web Management” on this guide.
If you are placing the G.DUO behind router or firewall, you might need to open virtual server
ports to G.DUO on your firewall/router
HTTP:
HTTPS:
TCP Port 80
TCP/UDP Port 443
This procedure is not necessary in most cases unless there is a router/firewall between
your PC and G.DUO.
3.4.1 Getting into Web Management
Normal Web Management (HTTP)
To get into the Normal Web Management, simply type in the G.DUO’s IP address (default IP
is 192.168.1.254) into the web browser’s address field.
Secured Web Management (HTTPS)
To get into the Secured Web Management, just type “https://192.168.1.254 ” into the web
browser’s address field. The “192.168.1.254” is G.DUO’s default IP address. If the IP
address is changed, the address entered in the browser should change also.
A security warning screen from your browser will then pop-up depending on the browser
you use. Please follow step below to clear the security screen.

Security settings allow you to use encryption to secure your data from eavesdropping.
You can select different security policy to provide association authentication and/or data
encryption. The G.DUO features various security policies including WEP, 802.1x, WPA,
WPA Personal, WPA2, WPA2 Personal , WPA Mixed.
WEP
WEP Encryption is the oldest and most available encryption method. However, it is also
the least secure.

Select one of the WEP key for wireless network: There are total of 4 possible keys
for WEP encryption. You need to choose which key will be used for encryption. All
wireless devices on the same network have to use the same settings. We
recommend using WEP Key 1 as in default setting.

Authentication: 2 types of Authentication are offered. Open system and
Shared key. If you are not sure which one to use, please select “Auto”.

Key Length: The G.DUO offers 64bit and 128 bit for WEP key length. The
longer the Key Length, the more secure the encryption is.

Key Type: 2 types are available: ASCII and HEX. ASCII is a string of ASCII
code including alphabetical characters, space, signs and numbers (i.e.
“airlivepass12”). HEX is a string of 16-bit hexadecimal digits (0..9, a, b, c, d, e, f).
All wireless devices on the network must match the exact key length and Key type.
Some Wireless clients only allow HEX type for WEP.

Fragmentation: When the size of a unicast frame exceeds the fragmentation
threshold, it will be fragmented before the transmission. It should have a value of
256-2346 bytes, with a default of 2346. If you experience a high packet error rate,
you should slightly decrease the Fragmentation Threshold.

RTS Threshold: RTS/CTS frames are used to gain control of the medium for
transmission. Any unicast (data or control) frames larger than specified RTS threshold
must be transmitted following the RTS/CTS handshake exchange mechanism. The
RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It
is recommended that this value does not deviate from the default too much.

Beacon Interval: The device broadcasts beacon frames regularly to announce its
existence. The beacon Interval specifies how often beacon frames are transmitted in
time unit of milliseconds. The default value is 100, and a valid value should be between
1 and 65,535.

AckTimeOut: When a packet is sent out from one wireless station to the other, it will
waits for an Acknowledgement frame from the remote station. The station will only
wait for a certain amount of time, this time is called the ACK timeout. In most
conditions, please put ACKtimeout value at zero(default value). The AP will calculate
the ACKtimeout automatically when the value is zero. However, you can also enter
the ACKtimeout manually.

Preamble Type: A preamble is a signal used in wireless environment to synchronize
the transmitting timing including Synchronization and Start frame delimiter. In a "noisy"
network environment, the Preamble Type should be set to Long Preamble. The Short
Preamble is intended for applications where minimum overhead and maximum
