DTIM: A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.
When the wireless router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1. Valid settings are between 1 and 255.
Beacon: Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value
between 20 and 1000 milliseconds.
WPS: WiFi Protected Setup is a method for easy and secure establishment of a wireless network. It can be used instead
of passwords when connecting clients that support WPS.
Short Slot: Slot Time is the period wireless clients use in determining if the channel is free for transmission. Enabling this
value allows clients that can utilize a shorter time to do so. Disabling this option forces all clients to use a longer backoff
check and thus may reduce network throughput while reducing the number of transmission collisions.
Wireless Mode: Select the WiFi clients the router will be compatible with. Greater compatibility is a tradeoff with better
performance. For greatest compatibility with all WiFi devices, select "802.11 b/g/n". For best performance, connect with
only other 802.11n-compatible devices and select "802.11 n."
 802.11 b
 802.11 b/g
 802.11 b/g/n
 802.11 n
Channel Width: Selects whether the router uses a single 20 MHz channel to send/receive, or uses two adjacent 20 MHz
channels to create a 40 MHz channel. Higher performance is possible with the 40 MHz channel. Selecting Auto is
generally best. Enabling WiFi as WAN will force 20 MHz only mode.
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.
