Most routers come with "dual-band" WiFi, which means they support both 2.4G and 5G WiFi frequency bands. They may use the same SSID (SSID = network name), or have a unique SSID, such as "YourWifi" and "YourWifi_5G". Since all eufySecurity devices work on 2.4GHz WiFi network frequency only, this article will guide you to connect your eufySecurity device to the correct 2.4GHz WiFi.
