Yes, the soundbar supports 2.4-GHz and 5.0-GHz Wi-Fi networks. If the soundbar was set up with a 2.4-GHz SSID network and you want to switch it to a 5.0-GHz SSID network (or vice versa), please reset the soundbar first before starting any setup. Please refer to “Apply factory settings” in the user manual. Remember not to hide the SSID name of the router while the network is being set up.
