AP 305 should be supported on 8.2.4, same is mentioned in the supported device guide for 8.2.4.
We cannot add a thin AP manually to Airwave using SNMP, Airwave polls the Controller and gets the AP info.
- Is this AP showing up on controller?
- Could we try to poll the controller on Airwave once? Do we see any error while polling?
- After polling could we double check the new devices list again?
Also, once the AP shows up you would have to do replace hardware if we still have the old 105 on Airwave so that historical data for the device wont be lost.
