How do I update the firmware on my Cox modem or router?

Asked 5 months ago
Updating the firmware on a Cox modem or router is an important step in ensuring that you have the latest features and security patches. Generally, if you rent equipment from Cox, the firmware updates are managed automatically by Cox. This means that you may not need to take any action at all. However, if you own your own modem or router, you may need to check for updates manually. To update the firmware on your own device, start by accessing the settings interface. You can do this by entering the device's IP address into a web browser. This address is typically found in the user manual or on a sticker attached to the device itself. Log in with your username and password, which may also be found in the documentation. Once logged in, navigate to the firmware section of the settings. There you will usually find an option to check for updates. If an update is available, follow the prompts to initiate the update process. It is crucial to avoid interrupting the power supply during the update. Once completed, your device should automatically restart. If you encounter issues or have further questions, it may be helpful to look for support resources on the current web page.
