Now to the problem:<br>
<br>
If I use laptop-2 in wireless mode everything works fine. If I
want to use a cable both Interfaces are getting the same address.
It manifests itself in a ip address conflict. How can I configure
DHCPd to avoid this? But I do not want to use more than one
address. <br>

Here is not DHCP problem at all.<br>
No problem if you will use one of wired or wireless interface, but
not both in the same time.<br>
<br>
If you are using both wired and wireless connection simultaneously,
you can't use same IP address on interfaces. IP address conflict
appears because your wired and wireless interfaces connected to one
network.<br>
