RUNNING，先激活。
[root@ localhost]# ifconfig wlp2s0 up [root@ localhost]# ifconfig wlp2s0 wlp2s0: flags=4099 UP，哈哈，也就是你的無線網(wǎng)絡(luò)信號，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，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，有ip地址表示網(wǎng)絡(luò)連接成功了 [root@ localhost]# ifconfig wlp2s0 wlp2s0: flags=4163 UP， width: 40 MHz，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。
經(jīng)過一番調(diào)查終于連上了，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。
留個(gè)筆記以備后用，。
1、首先，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。
查看無線網(wǎng)卡地址信息， center1: 2452 MHz ssid就是廣播信道名稱，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)。
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 ，紅色標(biāo)記的就是網(wǎng)卡。
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，BROADCAST。
