If you can't get into your router seems to be a bigger problem like chev said. Maybe you should try pinging your router to see if it is responding, by using the ping command (ping 192.168.0.1) then if it talk's back, you should try talking to google by the web address (ping www.google.com) then if tahts doesn't and does to (ping 74.125.132.99) then it's just a dns error but if it doesn't talk to either of the URL or the Ip of google, its a bigger problem
