Self-installation vs Professional Installation

  • Once the setup outside your home is done, you can get the kit and complete the installation on your time. There is no hassle of booking appointments, blocking your day, and waiting for the technician to arrive.
  • The only caveat with self-installation is you don’t get any on-site assistance. All you have is support over the phone from the technical support of Mediacom. With professional installation, all you have to do is wait until the technician sets up your internet.
