Inspiron: Wireless networks not showing up.

I have had my Inspiron 1525 for a year and a half now and the wireless network (I have Verizon Fios) has been working perfectly. Suddenly today, the wireless shut off and when I tried to reconnect it did not show any wireless connections in the area! Please help me, I need internet on that computer! I tried updating the drivers, but it was already up to date and I've looked all over for an answer, but still nothing! PLEASE help! The wireless works on other computers in the house, just not the Inspiron! How can I get my network to show up and connect?
