1.切換到超級使用者

[[email protected] ~]# su root

2.查詢可用的無線網絡卡，其中紅色為網絡卡號

[[email protected] ~]# iw dev
phy#0
Interface wls1
ifindex 2
wdev 0x1
addr 00:26:c6:c8:a1:96
type managed
channel 6 (2437 MHz), width: 20 MHz, center1: 2437 MHz

注意，如果成功連線網路的話，應該是下面這樣子的, ssid就是廣播通道名稱，也就是你的無線網路訊號呀，廣播通道就是最後一個

3.啟用無線卡

[[email protected] ~]# ip link set wls1 up

4.檢視無線網絡卡連線情況

[[email protected] ~]# iw wls1 link
Not connected.    （表示沒有任何連線）

(以下連線成功)

Connected to 2e:f0:a2:c7:2a:aa (on wls1)
SSID: iPhone 8
freq: 2437
RX: 1349315 bytes (12110 packets)
TX: 21864 bytes (169 packets)
signal: -38 dBm
tx bitrate: 65.0 MBit/s MCS 7


bss flags: short-slot-time
dtim period: 3
beacon int:

5.檢視所有可用的無線網路訊號

[[email protected] ~]# iw wls1 scan | grep SSID
SSID: iPhone 8
SSID: MERCURY_2.4G
SSID: 201
SSID: Loading
SSID: CU_Bonnie
SSID: TP-LINK e5532
SSID: clarence
SSID: lanwifi
SSID: ATAJ
SSID: 601\xe6\x97\xa0\xe7\xba\xbf
SSID: TP-LINK_DD21
SSID: TP-LINK_B429
SSID: aduhome
SSID: DYJ652
SSID: Tenda_582B78
SSID: xiaozhuzhijia
SSID: xymx-9-m
SSID: liuruiA-thena
SSID: Bonnie
SSID: TAT
SSID: CU_IbAZ
SSID: ATAJ
SSID: Bonnie_5G

6.連線無線網

[[email protected] ~]# wpa_supplicant -B -i wls1 -c <(wpa_passphrase "iPhone 8" "1234567890")
Successfully initialized wpa_supplicant

注意：其中iPhone 8為要連線到的wifi訊號SSID，1234567890為無線網路的密碼，請讀者替換即可。

7.分配IP地址（通過dhclient控制網絡卡進行網路操作獲取IP）

[[email protected] ~]# dhclient wls1

8.檢視無線網絡卡地址資訊，有ip地址表示網路連線成功了，可以上網衝浪咯

[[email protected] ~]# ip addr show wls1
2: wls1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
    link/ether 00:26:c6:c8:a1:96 brd ff:ff:ff:ff:ff:ff
    inet 172.20.10.4/28 brd 172.20.10.15 scope global dynamic wls1
       valid_lft 84511sec preferred_lft 84511sec
