other access points. However, you can also configure the root access point to copy the
release to all other access points in its spanning tree.

Using the MobileLAN access Utility

The MobileLAN access Utility enables your PC to act as a distributed upgrade server.
That is, the PC stores the upgrade software and you configure the root access point to
retrieve the software at a specified time. You can also configure the root access point to
inform other access points in its spanning tree where they can get the software so they
can be upgraded.
If you use this utility, you only need to configure the root access point and all access
points will be upgraded. However, when the access points request the upgrade software,
the utility must be active.
Note: To use this feature, the root access point must have software version 1.70 or later
loaded on it. The PC that is running the MobileLAN access Utility does not need to be
on the same IP subnet as the access points.
