A:AnswerTrue and False. You do need to be connected the the drive's hotspot in order to use it wirelessly, however the drive has a bridging mode that allows it to connect to other wireless networks. You can bridge the drive to your wireless network and be able to use the drive and Internet at the same time.
A:AnswerI set up my HDD on a Windows 10 PC, then I reset it and set it up back from my iPhone, it worked just fine on both. Also, we use it with Android devices with no issues.
A:AnswerI didn't have any issues buffering the video to my iPhone 6 Plus or my iPad. A friend of mine used his Android tablet to watch a few movies while on vacation. As far as speed of the HDD. It is plenty fast enough. The network connection / wifi connection is just like any other wireless device. The closer you are to the HDD the better. I actually watched a few movies on the pier at our summer cabin. The wireless drive was inside the house and I was outside, a few hundred feet away. No problems. If you are at all technical, you can figure out how to add it to your in home or portable router and expand the coverage even more.
A:AnswerI haven't tried that, I think it could be if HD is connected to a power supply or a PC, and you'll connect thru your modem. But, as it is portable, my recommendation is to take it with you, it works anywhere.
A:AnswerNot sure about international warranty. But you can always purchase the warranty under you name and if it breaks. Your brother can mail it back to you and you can bring it to you're local best buy. But you face the shipping costs...
A:AnswerTechnically yes, you have to make sure movies are in MP4 format. Then you have to load a different app than the WD app to play on the device. In practice what we have found is that the kindle does not have the processing power to play movies without hitching a ton. We have used iPhones, iPads and android tablets with great success.
