I have a wifi home network, And a laptop "D", that doesn't have wifi connectivity. I can plug it in to "W", one of wifi enabled computers via an Ethernet cable and now it's possible to get Internet connectivity using Windows Internet connection Sharing Service.
But according to my knowledge, the main wireless router doesn't know that this D's existence. Right?
In D, the OS is Debian and I added a route through W's Ethernet network IP. Then D can connect to other computers in the wifi network.
My problem is that how do I let other computers in the wifi network to connect to D? Is that possible?
I tried to add a route to the W's Ethernet IP in router's routing table. But its not reachable of cause.
