I bought a WD 3Tb MyBook Live NAS drive for use with Time Machine. It supports TM out of the box without any OS tweaks. I’m running OS 10.6.7.
TM won’t run longer than an hour. Almost every hour I see
Log entries:
5/6/11 1:53:04 AM configd[14] network configuration changed.
5/6/11 1:53:08 AM configd[14] network configuration changed.
5/6/11 2:53:22 AM configd[14] network configuration changed.
5/6/11 2:53:25 AM configd[14] network configuration changed.
5/6/11 3:53:41 AM configd[14] network configuration changed.
5/6/11 3:53:44 AM configd[14] network configuration changed.
The above happens with or without TM enabled and running. With TM running it looks like:

It seems that this network config change breaks the connection to the TM volume. Any ideas on what’s causing the network config change?
The WD drive and iMac are connected via ethernet (Not Wireless) to the same linksys WRT54GL router.
I posted this on the Apple support discussions as well.
