We are using WCS v126.96.36.199, a 4400 series WLC for Guest access, plus a mixture of 2100 series and 4400 series WLC's in our WIFI environment. The WLC's are running v188.8.131.52
I am running a unique client report in WCS filtering by our Guest SSID to establish which Guest users are accessing our WIFI network. However for most of the connections shown in the report the guest username field is blank. There are 1 or 2 usernames shown for some connections but not many.
I have checked the set up of the guest users and they are all the same with no difference to the ones actually showing in the report. In addition the guest users are connecting using the same foreign controller as the ones that are showing in the report.
Does anyone have any ideas why the majority of guest usernames do not show in the report ?
