Wifi On All The Devices In One Room Only Randomly Stopped Working?

I recently bought a new cisco e2000 router and had no problem connecting to it on all the devices in the house (about 10 of them)Just now, all the devices in my room (ipod, netbook, phone, and laptop) lost a connection to the router and no matter where I am in the house none of these 4 devices can get a connection. I can see other networks, just not mine. They all worked perfectly fine before, and out of nowhere they stopped working. Other devices that were not in my room at the time of this 'wifi surge' still have a connection to the router.The wired connection works and that's how I'm typing this right now.
