Although there are a few different possibilities for this error message, your radio may need to receive a firmware update for better router communication. The next time you receive the error message, don't touch the radio for 1 minute as it may need some time to access the firmware upgrade. If this doesn't work, then you might try using another WiFi connection (temporarily) to receive the firmware update on your radio. Thereafter you may return to your previous WiFi connection see if that resolves the issue. Alternatively you can always contact C. Crane customer service for further assistance and support.
