Portions of Configuration Might be Lost During Upgrade from 11.21 to 11.23T
If an access point or bridge configuration contains host names (ftp.cisco.com, for example) instead of IP
addresses in one or more configuration fields, the access point or bridge might lose some or all of its
configuration when you upgrade the firmware from 11.21 to 11.23T. Use IP addresses instead of host
names in all configuration fields when upgrading from 11.21 to 11.23T.
