  CentOS7命令行鏈接wifi教程

  1、首先,切換到超級管理用戶

  [user@localhost]$ su root

  2、檢查當(dāng)前可用的網(wǎng)卡,紅色標(biāo)記的就是網(wǎng)卡,這個(gè)并不是都是相同的

  [root@localhost]$ iw dev

  phy#0

  Interface wlp2s0

  ifindex 3

  wdev 0x1

  addr a4:db:30:84:4b:1c

  type managed

  以上是未連接網(wǎng)絡(luò)的打印信息,如果已經(jīng)連上則如下:

  [root@localhost]# iw dev

  phy#0

  Interface wlp2s0

  ifindex 3

  wdev 0x1

  addr a4:db:30:84:4b:1c

  ssid liylr

  type managed

  channel 11 (2462 MHz), width: 40 MHz, center1: 2452 MHz

  ssid就是廣播信道名稱,也就是你的無線網(wǎng)絡(luò)信號,廣播信道就是最后一個(gè)

  3、查看連接前的初始狀態(tài)

  [root@ localhost]# ifconfig wlp2s0

  wlp2s0: flags=4098 < BROADCAST,MULTICAST> mtu 1500

  ether 60:d8:19:cc:74:84 txqueuelen 1000 (Ethernet)

  RX packets 13547 bytes 13381624 (12.7 MiB)

  RX errors 0 dropped 0 overruns 0 frame 0

  TX packets 12659 bytes 1974514 (1.8 MiB)

  TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

  4、測試是否已經(jīng)鏈接網(wǎng)絡(luò)

  [root@ localhost]# iw wlp2s0 link

  Not connected.

  5、獲取SSID

  [root@ localhost]# iw wlp2s0 scan | grep SSID

  command failed: Network is down (-100)

  無線網(wǎng)絡(luò)未激活,先激活。

  [root@ localhost]# ifconfig wlp2s0 up

  [root@ localhost]# ifconfig wlp2s0

  wlp2s0: flags=4099 < UP,BROADCAST,MULTICAST> mtu 1500

  ether 60:d8:19:cc:74:84 txqueuelen 1000 (Ethernet)

  RX packets 13547 bytes 13381624 (12.7 MiB)

  RX errors 0 dropped 0 overruns 0 frame 0

  TX packets 12659 bytes 1974514 (1.8 MiB)

  TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

  6、查看所有可用的無線網(wǎng)絡(luò)信號

  [root@localhost]# iw wlp2s0 scan | grep SSID

  SSID: USER-20150101NS_Network_2

  SSID: Tenda_17BEF8

  SSID: PC-20140723DBVC_Network_1

  SSID: 123

  SSID: Tenda_0A6410

  SSID: xiaohui

  SSID: Tenda_51E4F0

  SSID: Nobody Can

  SSID: TP-LINK_3C479

  7、連接無線網(wǎng)

  [root@localhost]# wpa_supplicant -B -i wlp2s0 -c <(wpa_passphrase "Tenda_17BEF8" "useradmin")

  Successfully initialized wpa_supplicant

  Tenda_17BEF8是你想鏈接的SSID,useradmin為鏈接密碼。

  8、分配IP地址(通過dhclient控制網(wǎng)卡進(jìn)行網(wǎng)絡(luò)操作獲取IP)

  [root@localhost]# dhclient wlp2s0

  9、最后,查看無線網(wǎng)卡地址信息,有ip地址表示網(wǎng)絡(luò)連接成功了

  [root@ localhost]# ifconfig wlp2s0

  wlp2s0: flags=4163< UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

  inet 192.168.168.139 netmask 255.255.255.0 broadcast 192.168.168.255

  inet6 fe80::62d8:19ff:fecc:7484 prefixlen 64 scopeid 0x20

  ether 60:d8:19:cc:74:84 txqueuelen 1000 (Ethernet)

  RX packets 13567 bytes 13386147 (12.7 MiB)

  RX errors 0 dropped 0 overruns 0 frame 0

  TX packets 12682 bytes 1979923 (1.8 MiB)

  TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
