Thank you for the response. I did figure out to reset them. I've been meaning to post back on this for a bit. I would love to see a feature added to ROS to allow the ability to choose whether to use the old devices MAC addresses or just accept the MAC addresses of the new device. Unless there is way to do this already somehow. I can understand there would be reasons to keep the preexisting MAC addresses but I would have never expected this normally. I'll have to add that bit of knowledge to my memory banks. I'm sure I'll run into it again.
