# of WLAN (Deployed/Max/WLAN Group) 0 / 27 / 3I checked all possible settings like all WLAN Service Schedual is "Always on".
Setting static IP doesn't help much -- as you have to factory reset AP in the process, it will loose this setting anyway, but you can do it.
set scg command is redundant -- after upgrading image to vSZ image AP get this setting automatically from vSZ (actually it gets list of all external vSZ IPs).
Anyway, before AP will work after converting to scg image, you have to factory reset it once more. Only than it will work properly. It's a hard learned fact.
It may be that it was fixed in latest vSZ release, so -- I haven't yet chance to migrate APs from ZD to vSZ at the latest version, so can't say for sure. But at least until 3.2.0 it was mandatory to make factory reset after image is upgraded.
Hope it helps...
