Extended Channel:
When operating in 40 MHz mode the access point will use an extended channel either below or
above the current channel. Optimal selection will depend on the channels of other networks in the area.
MCS:
802.11n uses multiple Modulation Coding Schemes to enable higher throughput in various environments. Since
clients can dynamically change rates depending on environment, selecting
Auto
is generally best.
Short GI:
Short GI is an optimization for shortening the interval between transmissions. May be incompatible with older
clients.
Greenfield Mode:
Greenfield mode uses an 802.11n-only preamble to transmit packets that older wireless clients cannot
interpret. Use of greenfield mode in a mixed 802.11 environment may result in degraded performance but can improve
performance if all devices in the area are 802.11n compatible.
RADIUS Timeout:
(Default: 3600 seconds) When using an Enterprise security mode clients will be forced to re-
authenticate with the RADIUS server at this interval in seconds. This allows administrators to revoke access so when an
attached client‘s authentication expires, the client must re-authenticate.
RADIUS Retry:
(Default: 60 seconds) When using an Enterprise security mode, if a RADIUS query fails to receive a
response from the server it will delay by this interval (in seconds) before attempting another query. This helps protect the
network from floods of authentication requests if the RADIUS server is temporarily unreachable.
