Setting Bandwidth Limits on a WiFi Network
In the UniFi Controller, head to Settings – Profiles and click “Create New Bandwidth Profile”
Give the new bandwidth profile a name and the desired speeds and click “Apple Changes”
Go to Settings – WiFi and select the WiFi network we want to limit.
Choose “Manual” next to Advanced and click on the Bandwidth profile dropdown and select the bandwidth profile, then click the Apple Changes button to save the settings.
Once applied, all devices connected to the WiFi network will inherit that bandwidth limit.
