Cannot set Security Options to NONE

[ShepPlus]

I am trying to setup a Netgear r6300 as a "repeater" and the instructions say to frist change the "Security Options" to "None"....but I don't have the "None" option.  The only options I have are:

WEP

WPA-PSK [TKIP]

WPA2-PSK [AES]

WPA-PSK [TKIP] + WPA2-PSK [AES]

WPA/WPA2 Enterprise

set mode to 54 first then None should be an option
