Hi there, before search any post about, doesn’t find one so just wondering why I have only wifi channel from 1 to 7?

Regards.

Anyone can help me?
At least with only you check if you have wireless channel 8-13.
I have country setup to Japan and the channel frequency what I have are 2412-2442 Mhz.
Why I don’t have the other channels?

Most importantly: how do you determine that you only have channels 1-7?


First find out how’s your wireless set:

/interface wireless export

look for setting of “frequency-mode” and “country”. Then you can check for regulatory limitations

/interface wireless info country-info <country name>

Thanks to response mkx, I determine what I have only channel frequency 1 to 7 because I have only frequency channels into winbox/wireless table/Interface /Wireless/Frequency box.
To me is much easy for now use the GUI.

/interface wireless info country-info japan

I’m sorry, the cause was to use in channel with other setting than 20Mhz.
