I did a search, and found many posts with the same log messages, but none of the posts, or follow ups, addressed what they mean. The log entries are:
[INFO] Wed Jun 10 01:43:39 2009 guest: Unlock AP setup
[WARN] Wed Jun 10 01:43:39 2009 primary: Lock AP setup
I am using Firmware Version: 1.21, and Hardware Version: A3.
