If you select Managed Wi-Fi Service, we will evaluate your home at the time of install and add any necessary access points to ensure that you have excellent coverage. There is an additional monthly charge for each device added. If you are not interested inManaged Wi-Fi Service, Mi-Fiber provides one router and it will be as centrally located as possible to give you the best coverage with one device.
