Try this Tutorial
Let me just show you my interface. Quite easy IMO. Now I could not try it with other Laptop because I don't have any. So you must give this a try. I played CS and AoE2 a few years back but I never needed any software to connect. I just used the default Windows ad hoc network to join and it worked like a charm.
So here, have a look at the interface before going through the above tutorial

This was just to show you how to share an internet connection. The steps will remain same except where you have to select the network, you will select the network which you wish to share. You can have many clients, as my phone wasn't connected it was showing zero clients. Now go connect and try making a LAN for whatever game you wish to play.
That Android tethering is another easy option.
I have figured out a new way to play LAN games
Well i have only tested with NFSMW.
Because we are freshers and few of us have mouse and are comfortable with CS.
So all you have to do is find the most optimized android phone in your group
in my case we have HTC M8.
Because it has high processing power.
ok so lets just start with the process
Step 1)Create a hotspot through your android phone.
Step 2)Ask every peer to join the network you have created through cellphone.
This should be the perfect arrangement.
ie the solar system arrangement.

Well sorry i didnt mentioned that those boxes are Systems.
Reason to use High end phone?
Its about gameplay,so the hotspot system should serve the information to all the user simultaneously so you need some fast processors to carry out the iterations.
We have also tested with Moto E,the gameplay aint that smooth.
Glad if it helped
