Configure wireless NIC Driver in Ubuntu

A Ubuntu system was installed some time ago. Because there is no wired network connection, you can only use a wireless network card, and then find information about installing the wireless network card driver everywhere. Because my wireless network card model is mw150um. Therefore, I am very happy to install ndiswrapper using a method on the network and using a driver in windows. However, I found that the wireless Nic does not work after I upgrade the Ubuntu kernel.

At this time, repeat the previous steps does not work, so you can continue to search Baidu and find that the following methods may be the ultimate solution.

First, run lsusb to view the NIC model and other information.

Bus 001 device 004: Id 0133: 8176 RealTek semiconducorp. rtl8188cus 802.11n WLAN Adapter
Bus 003 device 002: Id 17ef: 600e Lenovo

Bus 002 device 001: Id 1d6b: 0001 Linux Foundation 1.1 root Hub
Bus 003 device 001: Id 1d6b: 0001 Linux Foundation 1.1 root Hub
Bus 004 device 001: Id 1d6b: 0001 Linux Foundation 1.1 root Hub
Bus 005 device 001: Id 1d6b: 0001 Linux Foundation 1.1 root Hub

From the above information, we can see that RealTek's chip is 8176, and the wireless network adapter is rtl8188cu802.11n WLAN adapter.

So download the latest standard driver from the http://www.realtek.com website, detailed address: http://www.realtek.com/downloads/downloadsView.aspx? Langid = 3 & pnid = 13 & pfid = 21 & level = 4 & conn = 3, and then select the driver that matches your Nic model.

The rest is streamlined: unzip, chomod + x install. Sh, sudo./install.

After the network adapter is finished, it starts to work.
