Brand New Asus Z54C-JS91 Wireless Default Gateway Not Available

I'm unable to access the router's settings anymore, as somehow the firmware managed to delete itself. When I try to access the page it gives me an "Error 404: File not found" page. I tried calling Comcast customer support about the issue, and there wasn't anything they could do on their end to fix it without me paying money. When I get back from Afghanistan I'll be looking into other internet companies, as Comcast service is terrible.

Also, a couple of hours ago my buddy actually did decide to return it and get a new one. Hopefully, my having upgraded it to Windows 7 Ultimate didn't void any kind of manufacturer's warranty...

Edit 1: Well, it would seem that the laptop was part of a bad batch. My friend called the customer service of the store he bought it from, and they said he was the second caller today who called about the wireless not connecting to networks. I guess that solves it.
