I've had this router for 2 years. When selecting to join a wifi network, I have never seen the option for 5GHz. Now that it might be useful for some of my devices to be on 2.4GHz and others 5GHz, I am seeing in the advanced tab that there's a red X next to 5GHz as if I have not set it up. But in the Basic > Wireless page, I have enabled it, given it a name and pw. I have also rebooted my router. Still nothing. Can anyone help?
Feed in your model number and check the documentation for your hardware.
Check the section in the manual Enable or Disable Smart Connect
Smart Connect selects the fastest WiFi band for your device. For Smart Connect to work, the 2.4 GHz and 5 GHz bands must use the same WiFi network name (SSID) and network key (password). That means that when you connect to the router with WiFi, you see only one SSID that connects to both bands.
