linux - [网络配置] 使用wpa_spplicant连接wifi,无法ping通网关,请问 这样的情况如何解决

配置环境:

出现情况:

场合:家、公司

ubuntu设置情况如下:

wpa_supplicant连接wifi:

wpa_supplicant.conf设置如下

# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant GROUP=wheel

network={
    ssid="TP-LINK_413"
    #psk=""
    psk=e69abb9b46dcbf8df67738a2eda466c54b3f12043e54157d58e097c3e19fa2e3

    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP TKIP
    group=CCMP TKIP
}

连接wifi:

# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd -B

结果如下:

查看wifi信息

# iwconfig

结果如下:

至此wifi连接完毕,附上一张路由上的主机列表,划线的就是ubuntu,不过收包、发包太少了

设置网卡IP:

# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

# auto eth0
# iface eth0 inet static

auto wlan0
iface wlan0 inet static

address 192.168.1.192
netmask 255.255.255.0

# home
gateway 192.168.1.253

# work
# gateway 192.168.1.1

network 192.168.1.253

设置DNS

# cat /etc/resolv.conf
nameserver 192.168.1.253
nameserver 8.8.8.8

重新启动网络服务

# service networking restart

结果如下:

启动wlan0:

# ifconfig wlan0 up
# ifconfig

结果如下:

ping网关

# vi /etc/resolv.conf
root@cubieboard-server:~# ping -c 4 192.168.1.253

    不需要解决,已经连续成功啦(CONNECTED)。加 -B 选项它才会自动 fork 到后台去。

    现在你可以用 dhcpcd 或者 dhclient 程序来获取动态 IP 地址了,然后就可以上网了。
