Peter,
Your router is probably not configured to allow the system to be used outside of the network.
Drop me a short mail at dj0qn (at) darc.de and I will send you my networking checklist that
walks you through the process.
The RRC's are only password protected if someone entered a password into them to begin with.
In this case, only a full factory reset will get you back in.
