This article introduces the knowledge about "such as deterioration of Ubuntu through wireless network installation Ubuntu Server after starting the system to connect to wireless network". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Because I couldn't connect to the network installation graphical interface or Network-Manager and other applications, I also tried to use ifconfig and iwconfig commands, but found that iwconfig command only supports WEP encrypted Wi-Fi network, not WPA-PSK encryption. Finally, the Wi-Fi network with WPA-PSK encryption is successfully connected by configuring the wireless network card through/etc/network/interfaces. The specific method is as follows:

1. Dynamic acquisition method to connect to Wi-Fi network

auto wlan0 iface wlan0 inet dhcp wpa-essid Wi-Fi Name wpa-psk Wi-Fi Password

P.S. If the security authentication method is WEP, change the last two lines to read:

wireless-essid Wi-Fi Name wireless-key Wi-Fi Password

2, static address way to connect Wi-Fi network

auto wlan0iface wlan0 inet staticaddress 192.168.1.Xnetmask 255.255.255.0gateway 192.168.1.1wpa-essid Wi-Fi Name wpa-psk Wi-Fi Password

Note: The wireless network card "wlan0" is the name of the wireless network card queried by the iwconfig command. It may vary.

Through the above settings, you can automatically start the wireless network card after booting and connect to the Wi-Fi network encrypted by WPA-PSK!
