2702s have had a number of issues, both I and E models depending on when they were manufactured. There were a couple of months where APs were getting a bad image. I haven't seen many I models lately, but E models don't get sold in as high of volume.
There have been issues with both DHCP and DNS discovery not working, as well as the AP sending the AUX port MAC address in the discovery. My experience has been that you can do a few things to help. Configure both DNS and DHCP (Opt43) methods of controller discovery. If that doesn't work, the ip helper/forward protocol discovery method helps when you can't put the AP on the WLC management address. Barring either of those, just configuring the AP via the serial cable generally works, but is less scalable and more labor intensive.
