What security features are turned on?
Have you tried turning all security off?

That and the IP Address mean that DHCP failed.

Turn off all security for troubleshooting.
Cross-post with more restraint.

More precisely, that its DHCP request to get configuration information
(from the DHCP server presumably built-in to the router) failed.

Best bet is to reset the wireless router to hardware defaults and start
over.

That's an address assigned by Windows when DHCP fails.

That's typical of NAT configuration by DHCP. Did you set that manually
or did DHCP do it automatically?

If DHCP worked, then the Default Gateway should be populated.

What router (manufacturer and model)? Did you buy a quality name brand
unit, or the cheapest thing you could find?

Irrelevant.

Likewise irrelevant.
