66xx/67xx Router Users Guide 143
802.11n Rate: 802.11n data rate. Set to Auto to use the highest rate possible
802.11n Protection: Select Auto or Off.
Support 802.11n Client Only: Whether only 802.11n clients are able to connect.
RIFS Advertisement: Select Auto or Off.
OBSS Co-Existence: Select Enable or Disable.
RX Chain Power Save: Select Enable or Disable, then set the timing parameters. When enabled,
the WiFi receiver will shutdown when the period defined in RX Chain Power Save Quiet
Time occurs.
RX Chain Power Save Quiet Time: The Access Point will change to power save mode after the
number of seconds designated when RX Chain Power Save is set to Enable.
RX Chain Power Save PPS: The duration in seconds the Access Point will be in power save
mode.
54g Rate: The rate at which information will be transmitted and received on your wireless
network. Not settable when the router is set to 802.11n.
Multicast Rate: the rate at which a message is sent to a specified group of recipients.
Basic Rate: the set of data transfer rates that all the stations will be capable of using to receive
frames from a wireless medium.
Fragmentation Threshold: used to fragment packets which help improve performance in the
presence of radio frequency (RF) interference.
RTS Threshold (Request to Send Threshold): determines the packet size of a transmission
through the use of the router to help control traffic flow.
DTIM Interval: sets the Wake-up interval for clients in power-saving mode.
Beacon Interval: a packet of information that is sent from a connected device to all other devices
where it announces its availability and readiness. A beacon interval is a period of time (sent
with the beacon) before sending the beacon again. The beacon interval may be adjusted in
milliseconds (ms).
Global Max Clients: maximum number of clients allowed to connect to the router
Xpress Technology: a technology that utilizes standards based on frame bursting to achieve
higher throughput. With Xpress Technology enabled, aggregate throughput (the sum of the
individual throughput speeds of each client on the network) can improve by up to 25% in
802.11g only networks and up to 75% in mixed networks comprised of 802.11g and 802.11b
equipment.
Transmit Power: select from 20%, 40%, 60%, 80% and 100%. The default value is 100% but
can be changed.
WMM (Wi-Fi Multimedia): prioritizes traffic from different applications such as voice, audio and
video applications under different environments and conditions.
WMM No Acknowledgement: the acknowledgement policy used on the MAC level. Enabling no-
acknowledgement can result in efficient throughput but higher error rates in a noisy Radio
Frequency (RF) environment.
WMM APSD: APSD (Automatic Power Save Delivery). APSD manages radio usage for battery-
powered devices to allow battery life in certain conditions. APSD allows a longer beacon
interval until an application: VoIP for example: requiring a short packet exchange interval
starts. Only if the wireless client supports APSD does APSD affect radio usage and battery
life.
