The configured Share Over device is currently attached to a network using DHCP
In Wired Router mode, you cannot share your Internet over the same adapter that your are getting your Internet from. Connectify creates a new network on the adapter you choose under Share Over. If this adapter is currently attached to an existing network, Connectify will stop you in order to avoid creating a networking conflict on the network that adapter is connected to. You must choose a different adapter from Share Over.
