Answer 1

你怎么wan口的设置是dhcp呢？如果是拨号，需要改成pppoe方式（设置宽带帐号和密码）
1)下面的log说明wan口没有拿到任何地址（ip，掩码和网关）
# W1 = DHCP : W = 0.0.0.0 : M = 0.0.0.0 : G = 0.0.0.0
2)路由器发出的dhcp请求，都是没有得到响应的：
0days, 00:39:27, DHCPC: eth1 recv no OFFER, DHCP Service unavailable

Answer 2

用户名密码认证失败，有可能是
1、用户名密码没有输入正确
2、MAC地址没有克隆到以前能够正常上网的（针对ISP绑定MAC地址）
3、用户名密码被ISP用某种方式加密或修改（针对电信星空极速）
