BGW210-700 Router broadcasting second hidden 5GHz network on top of configured 5GHz wifi network
To start, I have band steering turned off as 2.4GHz and 5GHz have their own names and passwords. The Guest network is off, and WPS is off. The 5GHz network is set at channel 36 with a channel width of 40MHz. The 2.4GHz network is auto channel with a width of 20MHz.
However, the router broadcasts a second 5GHz network with hidden SSID at the same channel and channel width as my configured network. I've confirmed this with a wifi scan utility from my smartphone. Why? And how can I turn it off?
