How quickly can you download pictures with a Kindle Fire HDX?

The Kindle Fire HDX supports the 802.11n wireless networking standard, enabling the tablet to download a typical 1 megabyte image file in less than a tenth of a second. However, actual speeds vary depending on practical factors that typically slow actual speeds below this maximum

Download speeds for any type of file are often limited by practical factors such as the hardware of the wireless network that a device is connected to and the interference with a network's wireless signal. For example, the Kindle Fire HDX is limited to download files at the maximum speed of a particular wireless network, so it cannot download an image as quickly if connected to an older 802.11g or 802.11b wireless network.
