This is my first writing on Android Forum. I just got a free Samsung Galaxy Tab 4 (4G At&T) and I planned to use this as a modem using wifi hotspot at home, cancelling my Cox cable internet service. I have unlimited data plan (even it slows down after 22GB data usage a month) and I am barely at home, so the wifi hotspot on my Galaxy Tab 4 would be perfect for my smart TV, labtop and my phone. The problem is my WD My Cloud Mirror. It does not have option to connect it via wifi, but it only works with Ethernet connection internet service. I looked up ethernet cable adaptor for the tab 4, but it does not have charging option (since I'm using it as home wifi hotpot while displaying the clock/calendar at home), and I am not sure if it is to receive internet service connection by connecting it to modem/router for tablet use, or it actually transfers data internet service from Tablet to My Cloud. Please advise... and let me know what kind of adaptor/device I need or other options I have... Please help me on this!!
