The ARRIS SURFboard Manager App is a simple way to manage your home Wi-Fi network from the convenience of your mobile device! For too long, users have not set internet access rules or managed the quality / availability of their home Wi-Fi network – simply because it was too complicated to access. The SURFboard Manager app simplifies that process. Plus, the Wi-Fi modems with McAfee Protection utilize the McAfee Secure Home Internet App with added features like managing settings by user profile, and providing notifications of new users attempting to access your network. This app removes the barriers to being informed about your Wi-Fi network and the devices connected to it
