I can’t seem to detect Cerise on my iPad

If connectivity is unreliable on iPads running iOS / iPadOS 26 or later, update Cerise to firmware 1.8.11. A typical symptom is Cerise appearing in Settings > Ethernet while the IP address and subnet mask fields are empty; Cerise does not respond and its WebUI cannot be reached. Use the computer-based USB update procedure linked above, then reconnect Cerise.

Firmware 1.8.11 improves reliability and sets the default USB IP address to 172.30.0.1 on all Cerise units. We recommend that all users update to 1.8.11 and use this default. The old workaround of changing the first two parts of the IP address is no longer needed.

The first step to check is that the BOOT/Update LED is Cyan, if it’s green, this means you don’t have a USB connection between Cerise and the iPad.

This could be due to various reasons :

• Faulty USB cable (make sure to use a cable that can at least do both USB 2.0 communication as well as power)
• Certain docks/dongles will have a USB type-C input connector for a charger, in certain cases they do not support data; the best workaround is to try one of the USB-A ports with a type-A to type-C cable
• Certain docks/dongles will also have a built-in ethernet card which might conflict with Cerise
