Will Easy Wi-Fi work with WEP-encrypted networks (such as SoftBank Mobile or NTT HOTSPOT)?
Yes. All you need to do is add one of these networks to your Easy Wi-Fi account, along with your username and password. Easy Wi-Fi will automatically set-up your device with the correct WEP key and other network parameters so you’ll automatically connect. Note: this currently is not completely supported on Apple iPhone/iPod/Mac OSX devices; you will have to manually add your security keys, thereafter Easy Wi-Fi will function normally.
