router will use 40MHz operation.
In both 20 MHz and 40 MHz operation, when the 802.11n mode is configured to
Automatic, the router will use dynamic channel selection to determine the best
channels to transmit in order for optimal operation.
● NPHY rate: Set the Physical Layer (NPHY) rate. These rates are only applicable when
the 802.11n mode is configured as Automatic.
● Automatic 802.11n protection: If you select this option, the router will use Request
to Send/Clear to Send (RTS/CTS) to improve the performance in 802.11 mixed
environments. If this is not selected, the 802.11 performance will be maximized under
most conditions while the other 802.11 modes (802.11b, etc.) will be secondary.
● Legacy rate: Set the Physical Layer rate. This option is only visible when 802.11n
mode is turned Off.
● Multicast rate: Specify the rate at which multicast packets are transmitted and
received on your wireless network. Multicast packets are used to send a single
message to a set of recipients in a defined group. Teleconferencing, videoconferencing
and group email are some examples of multicast applications. Specifying a high
multicast rate may improve performance of multicast features. The rates are in Mbps.
You can select Automatic, 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54.
● Basic rate set: Select the basic rate that wireless clients must support, either
Default, All, or 1 & 2 Mbps.
● Acceleration: Select None, or 54g+ (Xpress™). These features determine either
normal speed rates or accelerated rates. Set the mode to 54g+ (Xpress™) for the
widest compatibility. Set the mode to None if you are experiencing difficulty with
legacy 802.11b/g equipment.
● Enable VLAN priority mode: When selected, the router will advertise packet priority
using the VLAN tag.
● Beacon Interval: The amount of time between beacon transmissions. A beacon is
basically a heartbeat for a wireless client or router, sending out a signal informing the
network that it is still active. This should be set between 1 and 1000 milliseconds. The
default beacon interval is 100 ms.
● RTS threshold: The RTS Threshold is the minimum size in bytes for which the
