Can’t access Web setup page for Linksys wireless router

I can’t access the Web setup page for my Linksys wireless B router, model BEFW11S4. Browsing to the default IP address, 192.168.1.1, results in a page not found. Using the hardware reset button does nothing. Leaving the router powered down for a day does nothing. The setup CD is also clueless, claiming it can’t find the router.

I checked the IP address and Default gateway using IP config, and both addresses result in a page not found.

Any ideas? I’m beginning to think my hardware is toast.
