I have turn on AAA to enable radius authentication. However, I failed to login using the generated password by radius server, which end up I can't log into the router at all. To access this router again, I disconnected the router from LAN and tried using password-recovery measure but still fail. During password-recovery process, I have pressed ctrl+break couple of time but still fail to enter the romon mode.I've been doing this process more than 20 times but seems no use at all. Fyi, I m using router 2811. Really appreciate your advice on how to recover the password again.
