Setup problem - password - WRT300N

Question

Hey I'm having a problem setting up my router.
I'm stuck in the setup where it says "enter password". I tried a bunch of different passwords and for each one it says like "Checking system information, please wait..." with a task bar. When the task bar gets to 100% it pops up "enter password" again, and again I try a password and it goes to "Please wait" again.
And it keeps doing that over and over. I tried all the passwords I've ever used and "admin".
Help. What am I doing wrong?

This is warning, and may apply to your situation even though I had the problem with a WRT54. I bought it supposedly brand new, shrink-wrapped from Compusa. It came with no cable though it was supposed to - but an untwisted wire tie was in the box (a clue!).
It would not accept a password, even admin. Phone support moron wanted me to play a game of "guess the password" (did "it" have a clue as to how many combination of 32 characters there are?). When I ran ipconfig it was clear that the router was USED and someone had set it up with a password already.
It worked as a hard-wired router, and a novice may have continued to use it with no security.
Compusa exchanged it and was baffled about how it got on to the shelf - the "new" shrinkwrap was different in weight from the genuine stuff. I am undecided about whether Linksys is pawning off "Refurbs" as new or if Compusa is doing it or if some "customer" is attempting to create unprotected networks to take over.
