There is a bug in some devices in Netgear's implementation of password recovery. You can get locked into a close loop.
If password recovery is enabled, but you have not set the answers to the questions, it keeps sending you back to the beginning of the process because you can't answer the questions.
If the standard factory password (password) does not work, then you will have to factory reset the thing to get back to that. Then either disable password recovery (check the manual for your device) or provide some answers to those questions.
