Description
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.
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.
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 long guard
interval for data transmit based on the station capability.
Aggregation MSDU can
sizes.
It is used for improving MAC layer's performance
for some brand's clients. The default setting is Enable.
Setup Number of Spatial Stream for Vigor2132ac and
Vigor2132Vac.
Default value is 2 and connection rate could reach 1.3GBps.
This option is to define the length of the sync field in an
802.11 packet. Most modern wireless network uses short
