[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：
- 操作环境：ubuntu
- 网络连接：USB无线网卡链接WIFI
- 连接方式：wpa_supplicant
- 监测方式：iwconfig
出现情况：
- wpa_supplicant连接成功
- 能ping通网关、路由中也能查看到主机连接上
- 但不能ping通外网
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
