ubuntu18.04 8821CE network card driver
After installing ubuntu18.04, no wifi icon is found, then open "Settings" and find that the wifi shown in wifi does not find the wifi adapter.
It’s too old. After installing ubuntu so many times, I know that my pit has a problem with the computer network card driver. I need to download a driver that is the same as my network card driver. You can refer to: https://blog.csdn.net/tabgiver/article/details/103414573
