With the introduction of 6GHz channels the scan guard timeout should be adjusted to account for the following extreme case: - All 6GHz channels are scanned passively: 58 channels. - The scan is fragmented with the following parameters: 3 fragments, 95 TUs suspend time, 44 TUs maximal out of channel time. The above would result with scan time of more than 24 seconds. Thus, set the timeout to 30 seconds.
