My new iMac, my iPhone 4S, and my new MBP will connect to the MiFi Mobile Hotspot. However, neither of my iPads will connect. I keep getting the following message: "Unable to join the network MiFi" This is frustrating since we would like to be able to let our two boys connect to the internet while we are in the car. Any thoughts? FYI....they have no problem connecting to my home wifi network. Thanks in advance for any help!
