The previous design did not actually break from the wait loop when the AP changed back to 40 MHz channel and as such, ended up waiting the full 30 second time. Furthermore, the five second delay time for returning back to 40 MHz was not sufficiently long to test behavior correctly since the STA did not have any chances of returning the next coex report before the AP had returned to 40 MHz. Increase the AP wait time to 15 seconds so that the once per 10 seconds OBSS scan from the STA gets in before changing back to 40 MHz channel (after the 40 MHz intolerant AP gets disabled).
