That's the thing that is weird. The logs show a wlan-ap0 (IP is unnumbered, type is wlan-ap, description is a Service module interface to manage the embedded AP) interface is up as well as a Wlan-GigabitEthernet0 (IP is no IP address and type is Wlan-GigabitEthernet, description Internal switch interface connecting to the embedded AP) interface. I also now have a Null0 interface (No IP address and type null). None of these three interfaces existed before the power failure. I used to just have the name of the wireless access point I configured originally. On the front of the box, the Link light is lit, but the 2.4GHz light next to it is not. That's about all the information I have on the issue, not really sure what to do next.
I can't login to the internal AP so I can't see the AP configs, but judging by the fact that the interface names are not what I originally called them and the indicator light related to the radio is off, I'm guessing something got corrupted. I had saved the running config (once I got everything working) as the startup config before the power loss.
