This error means the hardware or network setup is sending unreadable data. It’s often caused by incorrect hardware, encryption settings, or misconfigured equipment. Ask the customer to contact their IT provider or the person who set up their network or captive portal to check the configuration.
What this means
This error indicates that the device sent a request the network couldn’t understand usually because of an incompatible or unreadable hardware setup.
Common causes
The wrong hardware type is connected
Encryption is turned on, making communication unreadable
Faulty or misconfigured hardware
Incorrect setup in the controller or router
How to fix it
Check that the correct hardware is being used for your site setup.
Ensure encryption or security settings aren’t blocking communication.
Restart your router or controller to refresh the connection.
If using a UniFi controller, confirm that hardware tokens are correctly configured.
If you’re not sure how to do this, please reach out to your IT company or the person who originally set up your captive portal and network to review the configuration.
