... whst is your q?

He quick set 20mhz.
But it applied 20/40mhz XX

maybe a bug....... but still its 20 mhz.... and 40....

Keep in mind that "Width" is in blue on Quick set so it was not applied yet. I see nothing wrong on the screenshot.

Be very careful with Quickset after you have made advanced changes with the conventional menus.

Quickset is only designed for the initial setup. After customizing with the advanced menu options don't return to Quickset to make further changes as often they are out of sync.

dont use quickset
