Question

linux

Good time, comrades.
There is a Wi-FI point, it is connected to my laptop, the laptop is running Ubuntu 15. The
task is, with this Wi-Fi for sure, to distribute the Internet to 2 other laptops via wi-fi.
Is it possible to implement this? If so, how?
Thanks in advance.

Answer 1

As I understand it, the laptop has some kind of Internet access not through a point, but, for example, through a 3G modem.
Everything is simple.
We say to the point that the router is a laptop (we indicate the IP address of the laptop), and at the point itself, for example, we raise a DHCP server that distributes our network settings to other devices.
An example is this:
192.168.1.2/24 - our laptop,
192.168.1.2/24 - our point,
192.168.1.3..254/24 - clients that go through the point
In the laptop OS, enter something like
route add default OUR_GATEWAY
Well, , if necessary, then
route add 192.168.1.0/24 OUR_GATEWAY
In iptables, do not forget to allow 192.168.1/24 to go where necessary.

Answer 2

Everything is ridiculously simple.
Click on the Wi-Fi icon - Connection settings - Choose a Wi-Fi connection - Change - IPv4 settings - "Shared with other computers" method
Everything, wherever the Internet comes from - Ethernet, 3G, Bluetooth - you distribute the Internet on Wi-Fi. If you distribute it on Ethernet, change the settings in the corresponding connection.
You may need to reconnect to the network.

Answer 3

From the main - cons: it's expensive, I understand that I don't want to buy a separate piece of iron.
I bought Zyxel Keenetic Gaga II for this, it has modes:
It connects to one point, and distributes the Internet / LAN from it via wire and via Wi-Fi, moreover, Wi-Fi on the same channel will be, for example, on the 3rd.
Another minus, he distributes it not very far, and also catches floors after 2 somewhere maximum, moreover, the greater the distance, the more often the Internet will disappear from the included microwaves.
