Ubuntu wireless network connection-Summary of errors and solutions (no specific process)

The biggest headache for Ubuntu over the past few days is that it saves a lot of trouble to connect to the network and update necessary software during installation.

Network connection, software package update, driver update during installation, it does not matter if the installation time is long, and it will save the time when it is depressing.

I cannot connect to the wireless network. Here I only want to talk about poor Wi-Fi signals or lack of wireless signals. let's first talk about all kinds of errors I 've encountered.

1. During installation, choose System Management> Software source> additional driver to enable the wireless network driver and connect to the wireless network. After the installation is completed and restarted, the status of the additional driver options will be restored automatically, the driver cannot be enabled.
2. Use a wired connection network during installation. After installation, enable the system and enable the driver in the additional driver options. However, if the WiFi switch is enabled, the Wi-Fi signal remains light. (It is unclear whether it is a system problem. In the first few installation times, WiFi will be enabled normally)
3. Do not connect to the network during installation. After installation is complete, there is nothing in the driver, and WiFi will not take effect.

These errors may cause you to be unable to enable the driver easily with the built-in tools of the system. Now, you have only installed the driver on your own.

There are two types of installation: one is to use the driver of the Windows system, the other is to download the driver of the Linux system corresponding to your Nic

1. Ndiswapper is required to install Windows drivers. This software can be directly installed in the Ubuntu Software Center, or you can download binary files and install them using commands.

• After direct installation, open the interface to find the INF file, but I don't know which INF is the driver of the wireless network card in windows. What should I do, the simplest way is to back up a NIC Driver with software such as driver life, and then decompress the compressed package and there will be an INF file.
• Binary installation is to download the ndiswapper Installation File, decompress the package, and run the shell command to install it.
• Both methods will encounter many errors during and after installation. Most of them are that the modeprobe module is not loaded, and the solution has not been implemented successfully.Mark

2. to install a Linux driver, run the following command to view the model of your wireless network adapter. Then, download the driver from the corresponding official website to install the driver. Google is recommended for the installation process.

• • How to view the model of the wireless network card, iwconfig can only see the hardware with the driver, lspci can see all the hardware, in general, you can find the information of your wireless network card at the bottom (which is the information of the wireless network card? You can see the hardware name in the Windows Device Manager. refer to the following link for details)
  • There are many errors here. Generally, an error is reported during binary installation. This is simple and rough. Update the software source and try again.

The specific error solution and software installation process can be implemented by Google Baidu. Here we just summarize some ideas and hope to help others.

Ubuntu has been tossing me for two weeks, and I have been reinstalling Ubuntu for nearly 20 times. I finally configured the J2EE environment yesterday. I don't want to open Ubuntu to the desktop today, so I got an error, the menu bar and left-side Navigation Pane are not displayed, so it is a bit disheartened at a time. When you are not familiar with an environment, you can use an environment for research and development. It takes too much time to adapt to the environment, in Windows, it is more convenient to study new technologies. You can set up your project to manage your environment, Linux, and wait for your brother to come back and toss you, instead of tossing you.
