pacman -S wireless_tools madwifi

在USB接口001/003上检测到网卡。
iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off
无线网卡为 wlan0
ifconfig wlan0 up
因为我的网卡必需要先激活才能扫描,否则下一步scan会出现错误:wlan0 Interface doesn’t support scanning.
iwlist wlan0 scan wlan0 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
发现WPA2-PSK/WPA-PSK 加密网络 TP-LINK_22E1D2,因为加密方式为 WPA-PSK 所以得用 wpa_supplicant 而不能使用 iwconfig wlan0 key xxx 形式,iwconfig key方式适用于WEP。
新建文件 /etc/my_wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant network={ ssid="TP-LINK_22E1D2"psk="密码"}
因为全部使用默认配置,所以配置文件非常简单。
wpa_supplicant -B -i wlan0 -c /etc/my_wpa_supplicant.conf -B Background 在后台以daemon 运行 -i interface -c 配置文件
ifconfig wlan0 192.168.1.131
ifconfig 查看状态
wlan0 Link encap:Ethernet HWaddr 54:E6:FC:03:0D:6B inet addr:192.168.1.131 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:95 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:32434 (31.6 Kb) TX bytes:576 (576.0 b)
我的网关的是192.168.1.1,添加通过wlan0访问的网关
route add default gw 192.168.1.1 dev wlan0
查看状态
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0 default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0
以后上线只需运行以下命令即可
wpa_supplicant -B -i wlan0 -c /etc/my_wpa_supplicant.conf ifconfig wlan0 192.168.1.131 route add default gw 192.168.1.1 dev wlan0
关闭连接
wpa_cli terminate
连接状态
wpa_cli status
