有人熟悉DD-WRT吗？把lan口改了配置----已解决

huangdog

昨晚DT的把路由器刷了个DD-WRT，一路顺利。。。

进去瞧瞧，各种乱七八糟的配置。。。

然后～看到lan口可以改成PPPoE，心想难道是连上路由器电脑还要连个pppoe才能正常上网吗？多好啊，这样外人就没法蹭网了。然后就改了，然后就顺手设了个用户名密码，然后就点了个应用，然后就果断悲剧了，现在是电脑连路由器不能获取IP，当然也不能登录进去修改配置了，尝试用设置的PPPOE帐号登录也没用，无法连接。

有木有这在方面精通的，怎么个修改法。TTL接口引出来了已经，SSH记得也开着，请各位指教！

已解决。

TTL启动进入安全模式，运行firstboot直接恢复初始化设置，或者运行 vi /etc/config/network直接修改配置也可以恢复。

串口进去nvram擦掉

我也搜到这个方法了，但是请教具体步骤和指令。现在登录到了 failsafe mode，下面提示root@(none):/# 要求输入命令，请指教什么命令。。。无奈Linux实在不了解。

没有复位按键吗？

貌似。。。这个版本的系统没有复位功能，复位键按了没用

对啊～要是能进去就不用这么DT了。。。现在连IP都获取不到，更别谈登录配置界面了

Tftp 强行刷rom

系统是好的，只不过配置有问题。现在不想再刷机，只想通过TTL把配置改回来。。。刷机有风险，搞不好就成砖了。。。不过现在也是半砖了。。。

贴上ttl信息，求助。。

路由有4个LAN,  难道你4个LAN都挂了?
nvram是用JTAG线才删的..  TTL不知是否可以
用TFTP再重刷固件不就得了..
