Ubiquiti UniFi known issues
Authentication delay
Symptom: When guests connect to a WiFi network managed by Social WiFi, they often experience a significant delay after clicking “Connect”. In some cases, the authorization process never completes.
Solution: Our internal testing indicates that this issue typically occurs when the UniFi controller is hosted outside the local network - such as on a VPS or in the cloud. We recommend using a local controller.
Local controller behavior
When the controller is deployed within the local network, UniFi Access Points (APs) communicate with it almost instantly, allowing for a smooth and immediate guest authorization process.
- Phone sends a request to the controller that goes through the Access Point
- User gets authorized on the controller
- Controller instantly sends the response back that the phone is authorized
- User gets authorized and can browse the internet
Externally hosted controller behavior
With externally hosted controllers, UniFi APs send an “inform” packet approximately every 30 seconds. As a result, the controller may take up to 30 seconds to notify the AP that a guest has been authorized. This delay negatively impacts the user experience, making the login process feel slow and frustrating for guests.
- Phone sends a request to the controller that goes through the Access Point
- The information is routed to the controller outside of the local network
- User gets authorized but the information can’t be sent back to the Access Point instantly
- Access Point checks for configuration update with the controller every 30 seconds
- When the Access Point checks in, only then the information goes back
- User gets authorized and can browse the internet
Internet access is not granted after login
Symptom: after connecting to the WiFi network, on the last step which is clicking the “Connect to the internet button” you’re not getting connected to the internet.
Solution: UniFi Access Points function as a DNS Proxy. Ensure that the domains are resolving correctly and that the Access Points have an active internet connection.
