Belkin n150 f9k1001V4

I have just bought a Belkin n150 router. Connected it to my modem and PC and I'm recieving internet. Connected my phone and laptop and getting wireless.

The issue, however, is that I cannot login to the router page. The login says to leave blank for default, but it gives me an incorrect password error. I have tried resetting using the button located above the power cable to go back to defaults, but I continue to recieve the error.

I have tried a all the other usual default passwords, password, administrator, admin, etc.

I'm at a loss. I've gone through pages of google search results and found nothing. Have I missed something obvious or did Walmart sell me a defective router?
