A:Answer Hello Ctf. The WF-4820 is designed to work on a home Wi-Fi router using a 2.4 GHz band. If the Wi-Fi router you are using is a 5 GHz router, you want to ensure that it is a dual-band router and the printer connects to the 2.4 GHz band. The "5G" you are inquiring about may refer to the network connection on a mobile device like a tablet or a smartphone, which would be entirely separate. However, if you are trying to connect this printer to a tablet or mobile device, it will work over a Wi-Fi connection, and you can use it by downloading the Epson Smart Panel application.
