NOTE! FW version 188.8.131.52 has a known problem when performing site survey when SU is not connected to a BS. SU will fail to scan and reboot. Workaround is to only update the basic tab, the site survey information will be updated since the SU is performing a scan in the background. If SU is connected to a BS it is Ok to perform a SiteSurvey. This issue will be fixed in future upgrade.
