Whenever I try to change my SSID, I get the following error.

Can someone give advice?
Maybe you first need to set your country ?
Do you have the same problem when using Winbox ?
Country is optional. Defaults to Latvia. And: interface configuration won’t show you inherited values from profiles. So it could actually be set in some profile already. Yeah.
What about CLI?
Setting country produces the same results. I am not familiar with CLI though. Winbox did the trick. Thank you. I have always thought it was quite difficult to read using Winbox. Seems I need to reconsider.
Thanks guys.
