Channel Width: You can choose 20MHz or 20/40MHz channel width. Choose
20MHz for compliance with laws in some countries. 40MHz offers faster performance
than 20MHz
Guard Interval: Guard interval is placed at the beginning of each transmission. It is
used to reduce the interference effect of multi-path transmissions. The use of long
Guard Interval may perform better in interference or multipath environment. However,
it can reduce the performance.
MCS (Modulation and Code Scheme): MCS level for the 11n mode. It is
recommended to leave it at Auto.
Decline BA Request: Enable this option to decline the Block ACK requests by other
devices.
BG Protection: The 802.11g standard includes a protection mechanism to ensure
mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists,
the two kinds of standards may mutually interfere and decrease network’s
performance.
