Have to reset router every now and then
Okay, so every now and then all of our Apple products (iPod Touch, iPhone and 2 iPads) suddenly can't connect to the internet. It just keeps on saying "Unable to join network." We usually fix this by resetting the router. The problem is that this only happens to our Apple products. My computer and laptop can use our wi-fi just fine. We only had this problem after we changed our router. Anyone know how to fix this?
