How to build WiFi for mobile phone in Ubuntu

Objective

My computer under the Ubuntu, Wireless has been a problem, the current problem is not to build WiFi, this problem is puzzling me for as long as a year.

After the Ubuntu upgrade to ubuntu14.04, the use of two foreign methods to build a mobile phone connected to the Internet WiFi.

Originally those who said that the computer does not support the construction of WiFi is all lies, under Windows can be built, to Ubuntu under how can not build it.

Can not build a friend could refer to my this, it is possible to build.

Body

Background

A year ago My computer failed to build WiFi, and then someone said that the default is not Ap-wifi, mobile phones can only connect access to the AP WiFi.

Well, it seems to have built WiFi is not connected, wrong, wireless signals are not found how to connect it? The computer itself can not even have their own wifi, then how to share the network?

A method that is ineffective for me

The way I'm ineffective is a lot of online, I don't have much to describe here.

It's not working for me, but it might work for everyone, so you can try mine first, and not try these, you might be able to build WiFi.

1. Create WiFi using the system's own features

The Ad-hoc is actually created, not the AP.

2.google code on the Wifi-hostapd-ap

Well, it hasn't been updated for years, and my successful WiFi failed.

3.hostapd+dnsmasq

A lot of configuration, but still failed.

4. Driver not supported

Some say the wireless card driver does not support, but I try to change they say oh, have failed.

5. WiFi not supported, I have proof

Front-end time there is a very hot csdn article, summed up a lot of WiFi methods, and finally use some methods to prove that some computer hardware in Ubuntu does not support the building of WiFi.

And I've been trying to get to the end of the article, and I found my exact match to what he said was not a supported computer.

The way for me to succeed

Maybe there are few people who have failed to build wifi like me, so there is no corresponding tutorial on the web.

But I never gave up looking, I even wanted to write a wireless drive to try, but now it seems not.

I found this tutorial (Http://ubuntuhandbook.org/index.php/2014/02/wifi-hotspot-ubuntu-laptop-android/).

First step: Install Ap-hotspot

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt-get update

sudo apt-get install Ap-hotspot

I finished the installation successfully.

Step Two: Configure

sudo ap-hotspot Configure

Well, I failed, prompted me not to support the AP or something, seems to be the following sentence:

Your Wireless card or driver does isn't support Access point mode

But it is understandable to look at the above remark.

Back to the column page: http://www.bianceng.cnhttp://www.bianceng.cn/OS/extra/

Supports for Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04. For Ubuntu 14.04, download & Install the Ap-hotspot Deb to saucy at this page.

Because I was using 14.04, I didn't see the sentence, so I went on to search the tutorial.

Step three: Go to the link and see for yourself.

Why do you let yourself see it? Because I failed in the second step, can not go on, the following I do not know how to do.

Kung Fu, I found another tutorial (http://ubuntuhandbook.org/index.php/2014/06/share-internet-with-android-ubuntu-1404/), It was written by the foreigner.

First step: Install PLASMA-NM

You can use the following command, but it is recommended to click on this link

sudo apt-get install plasma-nm

Step Two: Start the program

After you can use ALT+F2, search for Kde-nm-connection-editor

You can also enter kde-nm-connection-editor directly from the terminal.

Step three: Build a WiFi

Click Add to select Wireless (shared).

The SSID is the wireless name, like mine is Tiankonguse.

Mode Select Access Point.

can go to Wireless Security set a password, I chose the WPA & WPA2 Personal that item.

Fourth step: Connect WiFi

Generally click on the Internet icon, choose Connect to Hidden Wi-Fi network that item, Connection choose your new wifi.

Fifth step: Real connection WiFi

In the WiFi list is not see your wifi, click, enter the password for a while.

The tutorials are beautiful, the reality is brutal.

In fact, the second tutorial, when I built wifi in the third step, pops up a dialog box that prompts me that my computer does not support Ap-wifi.

Or the fourth step, it's not clear.

The contents of the box are probably

(a) Access point (AP) mode isn't supported by this device.

Then noon nap time, I turned off the computer to take a nap.

When I woke up, I found wifi in the WiFi list, and I clicked on it, and after a long wait I was connected.

Give it a try, you can really build WiFi.
