SSID
Advanced Settings
Vigor2760 Series User's Guide
It means the identification of the wireless LAN. SSID can be
any text numbers or various special characters.
The router offers 4 SSID groups to be configured for
wireless LAN. The default SSID groups are named with
"DrayTek1 to DrayTek4". We suggest you to change it.
These SSID groups can be configured by clicking on each
SSID item. Refer to the later sections for detailed
configuration.
Tx Burst - This feature can enhance the performance in data
transmission about 40%* more (for 11g station). 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.
Preamble Type - 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 field instead
of long preamble with 128 bit sync field. However, some
original 11b wireless network devices only support long
preamble.
Operation Mode - Mixed Mode allows the router to
transmit data with the ways supported in both 802.11a/b/g
and 802.11n standards. However, the entire wireless
transmission will be slowed down if 802.11g or 802.11b
wireless client is connected. Green Field allows the router to
get the highest throughput. Such mode can make the data
transmission happening between 11n systems only. In
addition, it does not have protection mechanism to avoid the
conflict with neighboring devices of 802.11a/b/g.
Channel Bandwidth - The router can use 20Mhz for data
transmission and receiving between the AP and the stations.
Or, it can use 20Mhz or 40Mhz for data transmission and
receiving according to the station capability. Such channel
can increase the performance for data transit.
