While operating in Access Point (http://en.wikipedia.org/wiki/Wireless_access_point) mode, displays the SSID
(http://en.wikipedia.org/wiki/BSSID#Basic_service_set_identifier) of the AirOS v5.3 powered device.
Security: displays the current security setting. "None" value is displayed if wireless security is disabled. WPA or WPA2 values are
displayed if the corresponding wireless security method is used. More information is provided in the Wireless section.
Version: shows the current firmware version. The device’s firmware can be updated on the System Page. Also you can check this
step-to-step tutorial (http://www.ubnt.com/wiki/index.php?title=How_To_Upgrade_Your_Firmware) for detailed instructions.
Uptime: shows the total time the device has been running since last power up (reboot) or software upgrade.
Date: indicates the current system date and time, expressed in the form “year-month-day
hours:minutes:seconds”. Accurate system date and time are retrieved from the Internet services using
NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol) (Network Time Protocol). System date and
time will be set to inaccurate default values after each reboot cycle if NTP is not enabled as most of the
AirOS based devices have no autonomous power supply for the internal clock.
Channel/Frequency: (http://en.wikipedia.org/wiki/Frequency) This is the operating frequency of the
802.11 (http://en.wikipedia.org/wiki/802.11) Service Set (hosted by AP) the client is connected to. 802.11 (http://en.wikipedia.org
/wiki/802.11) Channel (http://en.wikipedia.org/wiki/Channel_%28communications%29) number corresponds to the operating frequency
(http://en.wikipedia.org/wiki/Frequency) . More information about the supported channels is provided in the Wireless section. Device
uses the radio frequency (http://en.wikipedia.org/wiki/Frequency) specified to transmit and receive data. For 5 GHz operation (M5
series), the common range of available frequencies (channels) is 5.1-5.9GHz, for 2.4 GHz operation (M2 series) - 2412-2472MHz, for
900MHz operation (M900 series) - 902-928MHz, for 3GHz operation (M3 series) - 3300-3700MHz, and for 3.65GHz operation (M365
series) - 3650-3675MHz. Valid frequency range (channels) will vary depending on local country regulations. For more information
regarding frequency support, please visit the compliance section (http://www.ubnt.com/wiki/RF_Compliance) of the Ubiquiti Wiki.
Channel Width: This is spectral width of the radio channel used by AirOS v5.3 powered device. 5,
10, 20 and 40 MHz channel spectrum widths are supported. In Station (or Station WDS) Auto
20/40MHz is the value by default.
ACK Timeout (http://en.wikipedia.org/wiki/802.11#Frames) : displays the current timeout value
for ACK frames. ACK Timeout can be set manually or self-adjusted automatically. The ACK Timeout (http://en.wikipedia.org
/wiki/802.11#Frames) (Acknowledgement frame Timeout) specifies how long the AirOS device should wait for an acknowledgement from
a partner device confirming packet reception before concluding the packet must have been in error and requires resending. ACK Timeout
is a very important outdoor wireless performance parameter. When you are using 802.11n mode, it is recommended to set “Auto adjust”
for ACK Timeout. More information is provided in the Advanced settings section.
TX/RX Chains: displays the number of independent spatial data streams AirOS v5.3 powered
device is transmitting/receiving simultaneously within one spectral channel of bandwidth. This
ability is specific for 802.11n (http://en.wikipedia.org/wiki/IEEE_802.11n) devices that rely on
multiple-input multiple-output (MIMO) (http://en.wikipedia.org/wiki/Multiple-input_multiple-
output) technology. Multiple chains increase data transfer performance significantly. The number
of chains Ubiquiti device uses are hardware specific. Every TX/RX chain requires separate antenna. Bullet M series devices use 1
chain for transmitting/receiving (1x1). Nano/Loco M series and Rocket M series uses 2 chains for transmitting/receiving (2x2).
WLAN MAC: displays the MAC address (http://en.wikipedia.org/wiki/MAC_Address) of the AirOS
v5.3 device WLAN (http://en.wikipedia.org/wiki/Wireless_LAN) (Wireless) interface.
LAN MAC: displays the MAC address (http://en.wikipedia.org/wiki/MAC_Address) of the AirOS v5.3
device LAN (http://en.wikipedia.org/wiki/Lan) (Ethernet (http://en.wikipedia.org/wiki/Ethernet) )
interface.
LAN1/LAN2: indicates the current status of the Ethernet (http://en.wikipedia.org
/wiki/Ethernet) port(s) connection. This can alert the system operator-technician that LAN
(http://en.wikipedia.org/wiki/LAN) cable is not plugged into the device and there is no active
Ethernet (http://en.wikipedia.org/wiki/Ethernet) connection. When cable is plugged in,
negotiated data rate will be displayed; possible rates are 10Mbps or 100Mbps, or else Half
duplex or Full duplex.
AP MAC: displays the MAC address (http://en.wikipedia.org/wiki/MAC_Address) of the Access
Point (http://en.wikipedia.org/wiki/Wireless_access_point) where the device has associated
while operating in Station mode (or Station WDS). It is the MAC address of the AirOS v5.3
powered device's wireless interface itself if operating in Access Point mode. AP MAC is used as
Basic Service Set Identifier (BSSID) (http://en.wikipedia.org/wiki/BSSID) in infrastructure
type wireless networks.
MAC (http://en.wikipedia.org/wiki/Media_Access_Control) is unique HW
(http://en.wikipedia.org/wiki/Hardware) identifier on each 802.11 (http://en.wikipedia.org/wiki/802.11) radio. It consists of two parts:
An Organizationally Unique Identifier (OUI (http://en.wikipedia.org/wiki/Organizationally_Unique_Identifier) )
Network Interface Controller (NIC (http://en.wikipedia.org/wiki/Network_Interface_Controller) ) sequence.
The manufacturer list of a given MAC address (http://en.wikipedia.org/wiki/MAC_Address) is provided in this (http://standards.ieee.org
