Save this setting.3. Go to the 5 GHz Settings page to change the Wi-Fi name (SSID) and add 5GHz at the end of the name. Save this setting.New Wi-Fi names will appear on the Wi-Fi settings page of your phone.Note: After the Wi-Fi names are changed, you need to disconnect and re-add the devices to this router.
