Putting this here for now as the crappy Draytek support site won't let me regsiter due to no activation email ever arriving, so can't log a ticket right now!
AP962c works perfectly with 3 x SSIDs on different VLANs getting DHCP from the 2962 router...until...SSIDs are disabled over night per a schedule but when auto enabled again the next day, no DHCP IP for the clients...until...something is done on the AP web GUI, such as manually disable and re-enable one of the SSIDs, then everything works as normal. AP reboot also fixes it but that's a bit extreme and unnecessary.
Seems like a bug to me.
Anyone run into this or similar or got any ideas/opinons?
