Routers that support 5GHz will often operate under a dual-band mode and also support 2.4GHz devices. Refer to router instructions or contact the manufacturer for assistance. Use of a dual-band wireless network repeater/range extender that can connect to the 5GHz network will also allow 2.4GHz devices to be connected to the extended network. Please contact the Flo by Moen support at 1-844-MEETFLO (1-844-633-8356) for more information.
