Problems with handheld devices and wi-fi?

[Tigergirl97]

I came back from a two and one-half week vacation, and ever since my devices (mainly my Nook Color, my cell phone, and my iPod) haven't been connecting to wi-fi. I left my laptop at home and it still connects fine, so the router doesn't have a problem, just my devices and I would really like them to be connected because I want to be able to play games and stuff hahaha
So, erm, what should I do?
