Q: How to SSH into UniFi devices (Gateway/Switch/Access Point):
A: Enable "Device SSH Authenication" in the WebGUI first.
For UniFi Network Application 9.4 and above, the setting is under "UniFi Devices - (Filter Panel) Device Upadtes and Settings - (Side Panel) Device Settings - Device SSH Authenication". For older UNA version, the setting is under "Settings - System - General/Advance - Device SSH Authenication".

2. Check Status: info
   Example output:

root@UXGPro:~# info

Model: Gateway Pro
Version: 5.0.5.28767
MAC Address: d8:b3:70:3d:f8:11
IP Address: 119.17.158.255
Hostname: UXGPro
Uptime: 340616 seconds
NTP: Synchronized

Status: Connected (http://unifi:8080/inform)

3. Speed Test: ui-speed
   4. available on UXGs (including the UXG-Lite), UCGs, (and U7 APs?)
   4. Use case 1: ui-speed test - auto speed test using primary WAN and nearby remote test server
   5. Example output:

  root@UXGPro:~# ui-speed test
