This article mainly shows you "how to configure a wireless network in Linux". The content is simple and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how to configure a wireless network in Linux".

1. Install wireless_tools and madwifipacman-S wireless_tools madwifi2. Check the status of the network card lsusbBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hubBus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hubBus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hubBus 002 Device 002: ID 093a:2510 Pixart Imaging, Inc. Optical MouseBus 001 Device 003: ID 0cf3:7015 Atheros Communications, Inc.

The network card is detected on the USB interface 001swap 003.

The wireless network card is wlan0

3. Activate the network card ifconfig wlan0 up

Because my network card must be activated before scanning, otherwise there will be an error in the next step of scan: wlan0 Interface doesn't support scanning.

4. Scan the network iwlist wlan0 scanwlan0 Scan completed: Cell 01-Address: 54:E6:FC:22:E1:D2 Channel:1 Frequency:2.412 GHz (Channel 1) Quality=53/70 Signal level=-57 dBm Encryption key:on ESSID: "TP-LINK_22E1D2" Bit Rates:1 Mb/s 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s 54 Mb/s Mode:Master Extra:tsf=000000292a41bd80 Extra: Last beacon: 960ms ago IE: Unknown: 000E54502D4C494E4B5F323245314432 IE: Unknown: 010882848B960C121824 IE: Unknown: 030101 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher: CCMP Pairwise Ciphers (1): CCMP Authentication Suites (1): PSK IE: WPA Version 1 Group Cipher: CCMP Pairwise Ciphers (1): CCMP Authentication Suites (1): PSK

It is found that WPA2-PSK/WPA-PSK encrypts network TP-LINK_22E1D2, because the encryption mode is WPA-PSK, so you have to use wpa_supplicant instead of iwconfig wlan0 key xxx form, and iwconfig key mode is suitable for WEP.

5. Configure wpa_supplicant

Create a new file / etc/my_wpa_supplicant.conf

Ctrl_interface=/var/run/wpa_supplicantnetwork= {ssid= "TP-LINK_22E1D2" psk= "password"}

Because they all use the default configuration, the configuration file is very simple.

6. Connect wlan0 to the network and run wpa_supplicant-B-I wlan0-c / etc/my_wpa_supplicant.conf-B Background as daemon. Run-I interface-c configuration file 7. 0 as daemon in the background. Set the IP address ifconfig wlan0 192.168.1.131

Join the gateway to the route

My gateway is 192.168.1.1, add gateways accessed through wlan0
