Before changing your setup
Check the exact hub model, which indicator is lit, and whether it is flashing or steady. Those details matter more than colour alone. Each guide separates model-specific meanings, simple connection checks and the provider's official support route.
Appliance Faults provides independent guidance. We cannot test your line, check account activation or confirm a live outage. Use your provider's service checker for those questions.
