Use separate networks for wireless and wired. For the wireless networks, use some kind of ddns-hostname statement to set a name that is different in some fashion than what is used for the wired network. It’s been a while I since I’ve had to worry about this, but I remember adding “-wifi” to the ddns-hostname value for wireless networks.
