Sorry, but i can't find LAP rcv ios for the AP1252G in the wireless support download section for 1250ser. Does c1200-rcvk9w8-tar.123-7.JX9.tar from 1200 download section applicable for 1252 series?
The links in Scott's answer appear not to work (for me at least). This one might:
Also - Scott's instructions mention setting an IP address on the AP when using the "hold the mode button for 30 seconds" route. I don't believe that an IP address is necessary on the AP under those circumstances (based on few that I've done).
