Hi.. we currently have 5 AP's running for months now, boss wanted to add a 6th. I configured everything and plugged it in, but it never joined the WLC. After spotting a discrepancy in DHCP, I'm now wondering if this is a different model that isnt compatible with our setup.
DHCP is showing the working 5 as:
AP188B-4508 (WLC says AIR-AP1852I-B-K9 for model)
The non-working one is:
AP70F3-5A50 (Cant see it in WLC, dont know model of it, Id have to drag a ladder up there)
WLC is 2504:
Software Version | 8.3.140.0 |
Field Recovery Image Version |

That's right.
Once you put AP into same vlan as WLC management, then simple L3 broadcast from AP will reach to WLC & they will discover each other.
If you want to setup AP on other vlans (other than WLC mgt), then DHCP option 43 or DNS method is more practical.

No, you do not need both option 60 & option 43.
Simply configure option 43 with WLC IP to be advertised via dhcp.
Yes, "clear all config" should work, please verify it having console session to your AP directly

We use option 43 with static assignments. I'd recommend you not leave your AP's on normal dynamic IP assignment. The reason for this is: if your AP's are ever in a scenario where they cant reach the controller, they will fall back to DHCP and will re-request addresses from your DHCP server, making bad entries and filling up your DHCP scope.
