My Archer C5 (as client configured) thought there was a changing of channel and bandwidth, but it was actually not. The AP operated from the first time at channel 100 wlan ac vht20 and nothing was changed. My actual client setting was: channel auto, width 20mhz and it was according to the AP setting with its configuration: channel 100 width 20mhz.

I put the client channel to auto because the ap usually change its frequency because of DFS.
