I bought a 2TB MyBook Live and have managed to connect it up and using fine.
On my iPhone 5, I can connect by WiFi on the same network and on 3G fine. No issues.
I can connec to the drive from work using the wd2go website as well.
However, when using either my iPad Mini or iPad 2 with wifi on the same network as the MBL, the WD2go app detects my drive on the network but when I click on it, it comes up with an error “Unable to Connect to Device”. However, my iphone under the same scenario works fine.
I’ve downloaded the latest app and also the latest updates on the MBL.
