Here's the deal. I have a MacBook Pro which obviously has a wired LAN port and WiFi. I routinely back up my machine via Time Machine to my HP MediaSmart EX485. However, the machine obviously backs up slower over WiFi than it does over the LAN. So when I plug a network cord into my LAN port while at my desk (while the WiFi connection is still on), it doesn't automatically switch over to the faster wired connection. My solution now is to just temporarily disable WiFi while plugged in and then re-enable once I'm ready to go wireless again. Is there a utility to make this automatically happen, or is it just not working properly on my machine?
