Router Firmware

To avoid confusion, you need to remember one thing – when we say “router update”, we are actually talking about the router firmware update. Hmm, what is Firmware?

We believe that you know what the operating system is (Windows/macOS on computers or Android/iOS on phones) and that it manages all the functions of a device. The router also has its own operating system, and it’s called firmware. Manufacturers ship routers with pre-installed firmware. Every manufacturer has firmware for the exact model of their router.

Note: Certain Spectrum router models (all the latest models) receive updates automatically from Spectrum, and the whole firmware upgrade process is automated, so you don’t have to do anything. While the update is in progress, you will see red and blue pulsating lights.

Follow the next steps carefully:

Step 1 – Do not use a wireless connection when updating as this may permanently damage the router. You need to use Ethernet cables to connect the computer to the router. This would be the first step, put one end of the Ethernet cable in the router and the other in the computer (in a few seconds, the connection will be established).

Step 2 – Go to the website of the manufacturer of your router. Spectrum offers a variety of router models. We will show you how to update your Spectrum router on the example of a NETGEAR router).
