What your asking is ad hoc wireless sharing, You can do it manually but there is also one easy way to do it which is installing third party software. I have used this software on my laptop connected with LAN. I had no router at that time. This works flawless. You just need to install the app which is about 2 MB and configure it according to your need. And within few clicks your good to go.
