Remove the coaxial connection, or bypass a splitter by connecting the modem straight away. And then turn the electrical supply on. The online light should still be blinking. Another new splitter might be necessary for that situation.

Spectrum occasionally has system failures, which is terrible. You have to look for a nearby or widespread system failure if you are trying to set it up for your first attempt.

This has a very clear cause. If the network is down when you are encountering this problem. It will probably continue until it comes back online regardless of what you decide to do.

The Spectrum outage reporting page on the company’s official website is a more precise approach to checking this. You will also notice a message requesting your sign-in information to check for outages.
