Wi-Fi network with Internet distribution without a router?

Question

WiFi

There is a question. There is a class - 10 aluminum Macs. 2 of them are connected to the Internet.
Is there an option to organize the distribution of the Internet to other computers via Wi-Fi without a router. (Temporarily, for six months - a year).
Windows operating system. Although 3 operating systems are installed (Details here habrahabr.ru/blogs/personal/88451/ ).
How to do it right and is it worth bothering with it. For the educational process, you need the Internet, but so far there is no way to do everything according to your mind.

Answer 1

I have an opportunity. One computer that is connected to the network - configure the network in it in transmitter mode, find this network on the rest. You make the Internet connection on the transmitter computer “shared” - Windows will change the IP for the Wi-Fi connection for you, write the rest of the IPs on other computers manually. Select the Wi-Fi connection gateway depending on your Internet connection.
And even better - tell the version of Windows, they are different

Answer 2

The router costs 700 rubles, or even less. Don't suffer bullshit.
