How to get information about Wi-Fi clients?
Information on devices connected via Wi-Fi can be viewed in the web interface on the Client Lists page.

In this table, you can get the following information (using the third device on the list as an example):
Network name of the connected device (
HUAWEI-MatePad
);MAC address (
f6:48:6c:6a:9a:c5
);The IP address assigned to the connected device (
192.168.1.54
);Network segment to which the device is connected (
Home segment
/Wi-Fi 5 GHz
);Signal strength in relative value (as a graphical scale);
Current channel speed of the connection (
433 Mbit/s
);Network Security Protocol (
WPA2
/WPA2-PSK
);Connection standard (
11ac
— IEEE 802.11ac);Wi-Fi module configuration (
1x1
/1Tx1R
);Width of the channel used (
80 MHz
).
If you click on a client entry in the list, a device card with additional information will open:

Here, the system displays the client's online time (connection time) and the amount of data sent and received.
Additional and more detailed information is available via the router's command-line interface (CLI). To get it, run the command:
(config)> show associations

For example:
(config)> show associations

(config)>
* — WifiMaster0/AccessPoint0
is the interface name of the 2.4GHz network, WifiMaster0/AccessPoint1
is the interface name of the 2.4GHz guest network and WifiMaster1/AccessPoint0
is the interface name of the 5GHz network;
** — signal strength; a measure of the received signal strength; the higher the number, or the less negative it is, the stronger the signal; for more information, see How to check the signal strength and wireless coverage?
