USG40W: 5GHz not working

USG40W: 5GHz not working. I can't let my USG40W model broadcast 5GHz WiFi.

Answer
The built-in access point of the USG40W does only support 2.4GHz WiFi.

We would like to invite you to look at the datasheets of any USG model to check its specifications.

You can see the limitation in the attached datasheet of the USG40W.
