DunKerS :
It is connected to the same router, but it does not show the network. Rather than being called "Kevin's Network" (like it appears on all my wireless devices), it just says "Network".
"Kevin's Network" is probably the SSID (wireless ID) of your router. It doesn't indicate the name of your LAN.
As stated previously, any devices attached to the same router (wired or wireless) are part of your local network. The method by which resources are shared is dependent on the device.
How exactly do you want the devices to interact with each other? Video/music/picture sharing or something else? Also need to know what devices you are trying to get to "interact" (phones, tablets, OS, etc.). Some methods of interacting are built into an OS, while other devices (phones, tablets) might require you to install an app.
