Command line disable 2.4ghz radio

[slidermike]

I have my rt-N66U running 374.40 (merlin) in bridge mode.

The bridge is on the 5ghz channel, which I want but there is a yellow flashing exclamation point in the upper right indicating the wireless is insecure.
Since I know I set the 5ghz properly with wpa2 personal w AES AND the 2.4 radio light is also lit I am left to assume the 2.4 radio is indeed running as a default in bridge mode.
In bridge mode I no longer have access to the radio features individually so I am looking for the command line to run that will allow me to disable the 2.4 ghz radio.


I am very limited on my Linux knowledge but am guessing the command would be something like "nvram wl0 X"

Sorry if this has been asked but my search has not been fruitful.

Click on the yellow exclamation mark and it will fix it or take you to where you can.

L&LD,
thank you for the prompt response.
I did click the yellow exclamation & it brought up the small box that I showed in the screen cap.
That, in turn did not respond with a 2nd page or taking me to the gui to correct the issue.

I suppose that could be a browser issue (firefox) but what I did was reset the n66u to normal mode. Disabled the 2.4 radio then reverted back to the bridge mode & that seems to have worked.
