Create WiFi hotspot shared Internet access for Ubuntu laptop

This article is translated by the civil project, which is a translation. In fact, it can be easily configured without any commands. It is a graphical interface, which is convenient and easy. We all know how to design Wifi hotspots on windows 7. When you only have one network cable and multiple computers, you don't want to buy a router any more. How can we set Ubuntu computers as Wifi hotspots.

This article will show you how to set up Ubuntu 12.04 as a hotspot (point-to-point, access point) to share a wired network connection with other WiFi devices, such as laptops, iPad, iPhone, iTouch, and smartphones. Of course, Ubuntu of other versions is similar!

First, you need:

Laptop with WIFI hardware and WIFI Functions
Design Wifi hotspot laptop and Internet connection via Wired connection (WLAN)

Okay. Let's get started.

• Right-click the Network Manager (most laptops have wireless modules), connect to the Internet through a wired network (WLAN), select "Edit connection", and click it (for example, 1 ).

• For example, 2. Click "Wireless" in the menu, click "add", fill in the 3 dialog box, and enter the name in "Connection name, enter a name like "SSID" and select "Mode" as "point-to-point (Ad-hoc)". Other options do not need to be changed.

• The next step is to set up your Key (password) connection. Click "Wireless Security" and select "WEP 40/128-bit Key (Hex or ASCII )", enter your "Key (password)". If you don't want the whole world to share your WIFI, set a password (figure 4 ).

• Go to IPv4 settings (IPv4-Settings), select the Method option, 5 for Shared to other computers (Shared to other computers.

• "IPv6 Settings" is not changed. Click "save" to complete the settings, as shown in figure 6.

• Click the wireless icon in the upper-right corner, and then click the last option: "Create a new wireless network... (Create New Wireless Network ...)", 7.

Figure 7

• In the new pop-up window, select the created wireless network, the name I just set is "WIFI hotspot via LAN", and then click "Create, enter your password. (Figure 8 ).

• Now you can see that the "wireless network" is on your laptop, which means that the WIFI is connected by a computer instead of a wireless router (figure 9.

Figure 9

• All the work has been completed. Now, you can use a wireless connection (WIFI), which has been enabled for a Wi-Fi connection created for another device (figure 10), select it, and enter the key (password setting) (figure 11 ).

• Okay, now you can use Wireless Wifi for other devices!

Is it great, there is no command, all done by GUI image operations. This is the Linux operating system (Ubuntu 12.04). It is the only system that can create Wifi hotspots like Windows 7, and XP does not have this function!
