Weird thing... I set the AP to 20MHz:

ssid HolyLan

Then I reset the client and tried again and it still wants to use channel 153:
wpa_supplicant[16180]: wlan0: Trying to associate with 7a:d2:94:80:1f:ec
(SSID='HolyLan' freq=5765 MHz)
wpa_supplicant[16180]: wlan0: Authentication with 7a:d2:94:80:1f:ec timed out.

After a couple of dozens of retries the correct channel / frequency was finally
selected and connection was successfully established.
But it looks like the connection is 'a', not 'ac' that I expected?
