points do not retain their static IP address, netmask, hostname, and default gateway:

The LWAPP upgrade tool does not release Windows operating system memory resources when the
upgrade process is complete. Memory resources are released only after you exit the upgrade tool. If
you upgrade several batches of access points, you must exit the tool in between batches to release
memory resources. If you do not exit the tool in between batches, performance of the upgrade station
quickly degrades because of excessive memory consumption.

There are two different kinds of APs:

APs with a MIC

• 

APs that need to have a SSC

• 

Factory installed certificates are referenced by the term MIC, which is an acronym for Manufacturing
Installed Certificate. Cisco Aironet access points shipped before July 18, 2005, do not have MIC, so these
access points create a self−signed certificate when upgraded to operate in lightweight mode. Controllers are
programmed to accept self−signed certificates for authentication of specific access points.

You must treat Cisco Aironet MIC APs that use Lightweight Access Point Protocol (LWAPP), such as
Aironet 1000 APs, and troubleshoot accordingly. In other words, check the IP connectivity, debug the
LWAPP state machine, and then check the crypto.

The upgrade tool logs show you whether the AP is a MIC AP or SSC AP. This is an example of a detailed log
from the upgrade tool:
