This page allows users to set advanced settings such as operation mode, channel bandwidth,
guard interval, and aggregation MSDU for wireless data transmission.
Available settings are explained as follows:
Item Description
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- Vigor Router will use 20Mhz for data transmission and
receiving between the AP and the stations.
20/40 –Vigor Router will scan for nearby wireless AP, and
then use 20MHz if the number of AP is more than 10, or
use 40MHz if it's not.
40- Vigor Router will use 40Mhz for data transmission and
receiving between the AP and the stations.
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 long guard
interval for data transmit based on the station capability.
Aggregation MSDU
Aggregation MSDU can
combine frames with different
sizes. It is used for improving MAC layer’s performance
