Cannot change SSID in routeros 7.15.1

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.
