.
The startup and association sequence depends on the initial bridge configuration, as follows:
•
Default—The bridge attempts to associate with a root bridge for 60 seconds, and then it attempts to
associate with a non-root bridge. This timeout limits the amount of time you have to reposition the
antenna at the non-root location.

•
Preconfigured—The bridge attempts to associate with a remote bridge in the configured mode,
either root or non-root. Because there are no timeouts, it is easier to reposition an antenna with poor
initial antenna positioning.
