This page allows users to set advanced settings such as operation mode, channel bandwidth,
guard interval, and aggregation MSDU for wireless data transmission.
Operation Mode Mixed Mode – the router can 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 – to get the highest throughput, please
choose such mode. 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 20 - the router will use 20Mhz for data transmission and
receiving between the AP and the stations.
20/40 – the router will use 20Mhz or 40Mhz for data
transmission and receiving according to the station
capability. Such channel can increase the performance
for data transit.
Guard Interval It is to assure the safety of propagation delays and
reflections for the sensitive digital data. If you choose
auto as guard interval, the AP router will choose short
guard interval (increasing the wireless performance) or
