[问题] 关于 华为802.1x认证上网-5.18 失败 求助

[aman0821]

前面按步就搬,按照精华贴做,到了$ sudo /etc/init.d/networking restart这出来
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 5
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

若执行最后一步$ sudo linux1x -d 则长时间无法连接上,最后因超时而推出.
我用的是7.10版本 第一网卡等因该也没有设置错误,学校上网的配置也没问题.

请高手帮忙.
谢谢.
