It looks to me like the DHCP configuration on your router got messed up. I would recommend doing a factory reset by holding in the "reset" button, usually on the back or bottom of the router somewhere, for about 10-30 seconds (depending on model). You should see the lights go off, then start flashing on one by one as it resets and reconnects. From there, you can logon to the router to configure it, set password, etc. You logon to the router by navigating to the Default Gateway IP (generally 192.168.1.1) in your web browser. Let me know how this turns out for you. Cheers!
