[MLB-WIRELESS] Lost password to ASUS Wireless router

[Mike Dickens]

WL550ge to be exact, but all of the 500 range are extremely similar anyway.

I had dd-wrt installed, but I can't seem to get client mode to work on
it (just has all packets as Tx errors?), so I'm trying to go back to
either standard or oleg's firmware. Alas, for the life of me I don't
know what the password is - which seems silly, I can flash between
firmwares but can't login :P. How can I reset it?

As far as I know the default is admin/admin. Perhaps I'm getting this
part wrong?

Any help is greatly appreciated!
