No, No, Your router hardware has some issue!!! Either it has stopped talking to the computer in which case you'll have to restart your computer or you need to access your router page & choose Status (personally I've bookmarked the router page & have an auto-login.) But as yo suggsetd if yo can't access this page then, you modem has stopped communicating with your computer!!! Restart necessary! No bones about it!

If that doesn't work, pull your modem out for a few mins.
