CentOS7命令行怎么链接wifi
经过一番调查终于连上了,留个笔记以备后用,哈哈。
1、首先,切换到超级管理用户
[user@localhost]$ su root
2、检查当前可用的网卡,红色标记的就是网卡,这个并不是都是相同的
[root@localhost]$ iw dev
phy#0
Interface wlp2s0
ifindex 3
wdev 0x1
addr a4:db:30:84:4b:1c
type managed
以上是未连接网络的打印信息,如果已经连上则如下:
[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就是广播信道名称,也就是你的无线网络信号,广播信道就是最后一个
3、查看连接前的初始状态
[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、测试是否已经链接网络
[root@ localhost]# iw wlp2s0 link
Not connected.
5、获取SSID
[root@ localhost]# iw wlp2s0 scan | grep癫痫病的初期症状 SSID
command failed: Network is down (-100)
无线网络未激活,先激活。
[root@ localhost]# ifconfig wlp2s0 up
[root@ localhost]# ifconf治疗癫痫病专业医院ig wlp2s0
wlp2s0: 最权威的癫痫病专科医院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、查看所有可用的无线网络信号
[root@localhost]# iw wlp2s0 scan | grep SSID
SSID: USER-20150101NS_Network_2
SSID: Tenda_17BEF8
SSID: PC-20140723DBVC_Network_1
山东癫痫公立医院排名SSID: 123
SSID: Tenda_0A6410
SSID: xi腹型癫痫病的症状aohu治疗癫痫病比较权威的医院i
SSID: Tenda_51E4F0
SSID: Nobody Can
SSID: TP-LINK_3C479
7、连接无线网
[root@localhost]# wpa_supplicant -B -i wlp2s0 -c (wpa_passphrase Tenda_17BEF8 useradmin)
Success癫痫哪个医院看的好fully initializ陕西网ed wpa_supplicant
Tenda_17BEF8是你想链接的SSID,useradmin为链接密码。
8、分配IP地址(通过dhclient控制网卡进行网络操作获取IP)
[root@localhost]# dhclient wlp2s0
9、最后,查看无线网卡地址信息,有ip地址表示网络连接成功了
[root@ localhost]# ifconfig wlp2s0
wlp2s0: 最好的癫痫医院是哪家贵阳flags=4163 UP,BROADCAST,RUNNING,MULTICAST mtu 1500
