Where Did my 5ghz wireless network go? I can no longer see it or log in to it?

All of a Sudden I can’t see or log on to the 5ghz band of my dual band wireless router. Is there away that it might have gotten turned off, if so how do you turn it back on?

There is a manual for the R6220 somewhere at the end of this link:

>>> R6220 | Product | Support | NETGEAR <<<

Pages 47 and 119 explains how to configure the 5 GHz SSID. Other pages go into more detail.
