Configuring an Ethernet LAN and Wireless LAN is very simple. First you have to configure an Ethernet LAN with the help of an IP addresses. Now your Ethernet LAN network is setup. For configuring Wireless LAN, you need a wireless router and the nodes having wireless LAN cards. First configure your router to connect to your LAN network.
In a router there are WAN as well as LAN ports. While using the WAN port, first connects this router to the machine and configure wan port IP of router. You have to configure any free IP address in you LAN network to the WAN port of Router. Then enable the menu DHCP of wireless port in your router. Connect this router to your LAN using patch cord (in the WAN port of router). Install wireless LAN card in your nodes you want to use as wireless nodes, and enable the option "automatically obtain an IP address" in wireless LAN card settings. Now your wireless machines will get IP from your router and can access your network. This is your mixed network. Ethernet machines can be connected directly to network with a wire and wireless will be connected through wireless router.
