我的路由器密码忘记了,请问如何清除密码设置?答: 如果路由器的特权用户密码丢失,可以按照以下步骤进行恢复。 1. 准备一台运行仿真终端程序的PC ,推荐使用Procomm或者Windows Hyper Terminal(超级终端)。 2. 将PC的串口和路由器的控制台口用配套的控制线连接。 3. 路由器重启,在超级终端上执行ctrl+c ,使路由器进入Rom模式,出现以下菜单。 Main Menu:

Please select an item: 5 !此时config.text文件名已改为config.bak, !路由器找不到配置文件config.text,
!就会以默认配置运行路由器,

通过以上操作,将配置文件config.text改名为config.bak。这样启动路由器进入主模式之后,路由器找不到配置文件config.text,就会以默认配置运行路由器,这样就避开了原先配置的用户口令了。 4. 进入路由器的大版本,再把配置恢复回来,并且重新修改密码
进入大版本后,执行以下的操作来恢复原先的配置
NBR1000#dir !通过该命令,查看路由器上flash上的所有文件,其中
! config.bak是需要恢复的配置文件
! config.text是路由器生程的默认的配置文件
!现在就是要删除默认的配置文件,把备份的配置文件改名为默认配置文件

NBR1000#delete config.text !通过该命令,删除默认的配置文件config.text
NBR1000#
NBR1000#rename config.bak config.text !通过该命令, 把备份的配置文件config.bak
!改名为默认的配置文件config.text
NBR1000#copy startup-config running-config! 通过该命令,将配置文件拷贝到当前的运行环境中
通过以上的步骤,我们就把原先在rom版本改名的配置文件恢复回来了,现在您要做的只要把enable密码修改一下,记住修改后的密码,下次进路由器用修改后的密码登陆,就没有问题了.
