Internet Sharing 3G modem to two or more computers

a couple of weeks ago I came across several people who were started on their journey through the internet to purchase one of these devices 3G wireless Internet. One of the many doubts that arose in these new Internet users, future lovers Facebook, hi5 or Travian, like me, was whether he could share the internet signal of these wonderful devices in two or more computers simultaneously.

As with telephony these companies, which offered the service of 3G wireless intenet, not given any solution (for commercial matters) and then of looking for the solution on the Internet are only fragments of it on some forums (for Being basic concepts of networks), I decided to make this entry and clear once and for all the complete solution to share the internet from one computer to another using the connection internet of a 3G wireless router.

computers for connecting to 3G wireless router will need:

2 Cables Network (a cable for each computer to connect)
1 Router with AC power 3G wireless carrier

Modem Laptop or Desktop PC (For used as Internet server)
Desktop or Laptop PC (for internet sharing)

First Step:

Connect per diagram 1, the PCs with the router are connected via direct ethernet cable (which usually We sell in any sale of computer hardware).

Figure 1: Network Design Where

USB 3G is plugged into the PC Server. The PC server is connected via an ethernet cable to the router and PC to share (PC clients) are connected to the router via ethernet cables.

Second step:

Configure the router to have the following settings

WAN Settings (Settings on the side of the PC server):

IP address: 192.168.1.2 netmask
: 255.255.255.0
Gateway address 192.168.1.1

LAN Settings (Settings on the side of the client PCs):

IP Address: 192.168.130.1 (For this case, but you can choose which they wish to not be equal to the set during WAN, I will use these settings)
available IP Range: 192.168.130.2 to
netmask 192,168,130,255: 255,255 .255.0

To configure your router I recommend reading the user manual, there will be more explained according to the model of router with that count.

Step Three: Configure
network properties on the local network on the laptop or PC to use as Internet server with the following information:

IP address: 192.168.1.1 netmask
: 255,255. 255.0
Address Gateway: DNS
: You can use your choice depending on the case

Internet Server

Step Four:
In the laptop or PC to use as Internet server open Control Panel> Network Connections (Figure 2), there select the icon of the 3G wireless modem and enter the properties of this connection.

Figure 2: Image of the Network Connections window

Advanced Properties Select the bullet will enable the option "Allow other network users to connect through the Internet connection of this team," should look like Figure 3.

Step Five: Configure

network properties on the local network on the laptop or PC to share Internet with the following information :

IP address: 192.168.130.2 Subnet
:
255.255.255.0 Gateway Address: 192.168.130.1 DNS
: You can use your choice depending on the case

If you want to connect another PC to share internet the only thing that would change the IP address, which would be: 192.168.130.3, if need one more IP address would be: 192.168.130.4, so forth.

will be remembered that the more you put PCs on the LAN side of the slower the internet that the router gives these latter, besides the priority in using the internet always has the PC Server.
This would be explained in a simple, as they share with most computers, the internet, take longer to open a website.

Step Six:

Connect 3G wireless router using the software provided by your company prooveedora service (typically, this software is within the 3G router).
