Ubiquiti Networks, Inc.
Channel/Frequency Displays the channel number and
corresponding operating frequency. The AirRouter HP
uses the channel/radio frequency specified to transmit
and receive data. Valid channel/frequency range will vary
depending on local country regulations.
Channel Width This is the spectral width of the radio
channel used by the AirRouter HP. 5, 10, 20 and 40 MHz
channel spectrum widths are supported. In Station (or
Station WDS) 20/40 MHz is the value by default.
ACK/Distance Displays the current timeout value for ACK
frames. ACK Timeout can be set manually or self-adjusted
automatically. The ACK Timeout (Acknowledgement frame
Timeout) specifies how long the AirRouter HP should
wait for an acknowledgement from a partner device
confirming packet reception before concluding there
must have been an error and resending the packet.
TX/RX Chains Displays the number of independent
spatial data streams the AirRouter HP is transmitting/
receiving simultaneously within one spectral channel
of bandwidth. This ability is specific for 802.11n devices
which rely on multiple-input multiple-output (MIMO)
technology. Multiple chains increase data transfer
performance significantly. The number of chains Ubiquiti
device uses is hardware specific. Every TX/RX chain
requires a separate antenna.
WLAN MAC Displays the MAC address of the AirRouter
HP as seen on the wireless network.
LAN MAC Displays the MAC address of the AirRouter HP
as seen on the LAN (Local Area Network).
WAN MAC Displays the MAC address of the AirRouter HP
as seen on the WAN interface. This is the AirRouter HP’s
MAC address that is seen over the Internet.
WAN/LAN Indicates the current status of the WAN and
LAN Ethernet port connections. This can indicate that a
cable is not plugged into a device and there is no active
Ethernet connection.
AP MAC Displays the MAC address of the AirRouter HP
in Access Point or Access Point WDS mode. In Station or
Stations WDS mode, this displays the MAC address of the
Access Point the AirRouter HP is associated with.
Connections Displays the number of wireless devices
connected to the AirRouter HP when the device is
operating in Access Point or Access Point WDS mode. This
value is not displayed while operating in Station or Station
WDS mode.
Noise Floor Displays the current value of the noise level
in dBm. Noise Floor is taken into account while evaluating
the signal quality (Signal-to-Noise Ratio SNR, RSSI).
Transmit CCQ This is an index of which evaluates the
wireless Client Connection Quality. The level is based on
a percentage value where 100% corresponds to a perfect
link state.
Airmax Indicates the AirMax status (Ubiquiti’s proprietary
TDMA polling technology) when operating in Access
Point or Access Point WDS mode. If AirMax is enabled, the
AirRouter HP will only accept AirMax clients. (Disable
AirMax for legacy 802.11/jointfilesconvert/218032/bgn device compatibility). AirMax
also features advanced QoS Autodetection settings.
Airmax Quality This displays the AirMax Connection
Quality. The level is based on a percentage value where
100% corresponds to a perfect link state.
Airmax Capacity This is an index of maximum data
rate the link is operating at. A Lower Capacity number
indicates a unit that is bogging the system down.
Monitor
There are various monitoring tools accessible via the links
on the Main tab. The default selection is Throughput which
is displayed as soon as you open the Main tab.
Throughput
Shows a visual representation of the current data traffic
on the LAN and WLAN in both graphical and numerical
form. The chart scale and throughput dimension (Bps,
Kbps, Mbps) changes dynamically according to the mean
throughput value. The statistics are updated automatically.
Throughput statistics can be updated manually using the
Refresh button.
Stations
This selection lists the stations which are connected to
the AirRouter HP while operating in Access Point or Access
Point WDS mode.
The following statistics for each station are displayed in
the station statistics window:
Station MAC MAC address of the associated station. This
is a clickable link that will display additional station info.
Device Name Displays the client’s host name (if defined).
Signal/Noise, dBm Signal value represents the last
received wireless signal level, and Noise displays the value
of the noise level.
Tx/Rx, Mbps Tx value represents the data rates, in Mbps,
of the last transmitted packets, and Rx value represents
the data rates, in Mbps, of the last received packets.
