Why can my Toshiba NB550D netbook no longer connect to our router?

My netbook suddenly went offline. After several attempts to re-connect by clicking on the WiFi signal indicator, no luck. Thus, I decided to restart the netbook. And there’s when my problems started. I can not even connect to our router with the message “Windows unable to connect to (WiFi signal name)….”. Any suggestions?
