Default Admin/Netgear1 Logon Doesnt Work (#8463338)

Suggestions gratefully received for the following problem

I used Reset to reload the firmware and now it refuses any passsword that I know. What do I do? The full sorry saga is below

Bought a Duo 2120 in Jan 2011
Loaded 2 x 2tb disks and RAIDed it
Used it happily in a mixed PC/Mac environment for 6 months

And then the big mistake; Upgraded a MacBook Pro to Lion

Time Machine stopped working - but all was not lost
Uploaded the new firmware
All worked well that day

Then the Mac stopped finding the ReadyNAS
Then it found it but couldn't login

So I decided to go back to basics and do a Reset as per the manual and start again with the backups - I wanted to change how I use the NAS anyway.

Now the thing won't recognise the default ID (admin) and/or Netgear password (password), the older default Netgear password (1234) or the admin password I had previously used to access the device minutes before the Reset. I had used that password on the original firmware and the password was carried over during the Reset. The password prompt facility was lost during Reset.

I can access the drives over Windows Explorer but not open the admin function

HELP (and don't upgrade to Lion until Apple and Netgear have debugged their software)
