Anywhere Backup failing on wireless LAN

I have a MyBook World drive connected to my router via ethernet cable. All of my computers (4 Mac Leopards and 1 Windows XP) connect to the router wirelessly. On all of the Macs except one, WD Anywhere Backup fails to start backups when the computer first starts up. The software starts, but doesn’t back anything up. I have to start the backups manually every day. I believe that the Anywhere Backup service is starting before the wireless connection and fails because it can’t connect to the backup device. Is there some way I can force Anywhere Backup to wait 60 seconds or so before starting?

Since it’s been a while you might want to contact WD’s Technical Support about this.
