Acer RT-AC3200

Mary bought an Acer RT-AC3200 and she's having trouble with it. All her devices were disconnected from the 2.4Ghz band. The 5Ghz band is OK. It isn't congestion either because she lives out in the country. She's rolled back her firmware and Asus even sent her another modem. Leo says that sometimes the antennas may loosen and that could cause connection issues. Leo has had similar issues and it may be that the band gets overloaded and drops out everything. It could also be interference from the house itself. It could be radio interference that resonates close to the 2.4 Ghz band.
