Hi, dear user.
Yes, the device supports 5G Wi-Fi. By default, the 2.4G/5G Wi-Fi names are the same. The device automatically connects to an optimal frequency band. To fix the connection to the 5G frequency band, disable the Dual-Band Steering as follows:
Connect a mobile phone to the Wi-Fi network of the edge ONT.
Enter the IP address in the address box of a browser and press Enter. (For details about the IP address, see the product nameplate.)
On the displayed login page, enter the login password as prompted.
Choose My Wi-Fi and turn off Dual-band Combination. Then, two Wi-Fi names are displayed. Connect to the Wi-Fi with the suffix _5G.
Thanks.
