Could someone please help me find (page#) where in the IEEE 802.11 standard it directly says that Access Points are responsible for choosing the channel/frequency to be used and not clients. I know it's in there somewhere but I can't find where it says that in plain text and was hoping maybe someone on here is more familiar with the standard may know.

  • \$\begingroup\$ p.s. my marketing team is literately telling me we need to fix this feature, ie. clients choose wifi channel because my predecessor has this option in the gui but it doesn't work(wpa_sup) and now doesn't believe me when I say you can't do this, hope you enjoy that \$\endgroup\$

Channel usage information is provided by the AP to the non-AP STA to recommend channels for noninfrastructure networks or an off-channel TDLS direct link. The non-AP STAs can use the channel usage information as part of channel selection processing for a noninfrastructure network or an off-channel TDLS direct link.

At page 58.

The AP Channel Report element contains a list of channels where a STA is likely to find an AP.

At page 580.

The Channel Switch Announcement element is used by an AP in a BSS, a STA in an IBSS, or a mesh STA in an MBSS to advertise when it is changing to a new channel and the channel number of the new channel.

At page 490.
