Setup guide

Channel: This is the 802.11 channel number that corresponds to the operating
frequency. Device uses the selected channel to transmit and receive data. More
information is provided in the Link Setup section.
Antenna: This shows which antenna option the AirOS device is using currently. Most
of Ubiquiti Devices have 4 antenna options: vertical, horizontal, and Adaptive Antenna
Polarity (AAP) options. There is also often an external antenna option.
Security: This is the current security setting. More information is provided in the Link
Setup
section.
ACK Timeout: displays the current ACK Timeout value, which is set on the device
manually or adjusted automatically. The ACK Timeout (Acknowledgement Timeout)
specifies how long the AirOS device should wait for an acknowledgement from partner
device confirming packet reception before concluding the packet must have been in
error and requires resending. ACK Timeout is very important outdoor wireless
performance parameter. More information is provided in the Advanced settings section.
Transmit CCQ: This is an index which assesses the connection quality of the link. It
takes into account transmit errors, latency, and throughput while evaluating the ratio
of successfully transmitted packets against the re-transmitted ones and taking into
account current rate ratio against the highest specified rate. The level is based on a
percentage value where 100% corresponds to a perfect link state.
QoS Status: displays the current QoS setting. Quality of Service (QoS) can be enabled
to direct link speeds to better service particular customers and/or particular
applications like VoIP and video which require greater consistency, stability, and lower
latency performance.
Uptime: This is the running total of time the device has been running since last power
up (hard-reboot) or software upgrade. The time is expressed in days, hours, minutes
and seconds.
Date: indicates the current system date and time, expressed in the form “year-month-
day hours:minutes:seconds”. System date and time can be retrieved from the internet
services using NTP (Network Time Protocol).
LAN cable: displays the current status of the Ethernet port connection. This can alert
operator/user/technician that LAN cable is plugged into device and there is an active
Ethernet connection.
Host Name: displays the customizable name (ID) of the device as it will appear in
popular Router Operating Systems registration screens.
LAN MAC: displays the MAC address of the AirOS device LAN (Ethernet) interface.
LAN IP Address: displays the current IP address of the LAN (Ethernet) interface.
WLAN MAC: displays the MAC address of the AirOS device WLAN (Wireless) interface.
WLAN IP Address: displays the current
IP address of the WLAN (Wireless) interface.
