My Wifi Disappeared?

[Bawstun]

I've been using an open connection for my apartment building lobby for over a year, but all of the sudden it isn't recognized in my iPhone 4 or iPad anymore. My laptops still do. Other networks show up, but not this one. Any ideas?

Maybe the apartment building shut off the wifi? There's no other reason it wouldn't be finding it. Unless all of a sudden you're out of range...
