I just got a WD My Cloud. It is working great but I have one big disadvantage, the speed. My router is downstairs and my computer is upstairs almost right above it. Still, I let a backup ran for 24 hours and it was like at 30% so it would take 3 days to do a backup? I began searching online for improving my wifi speed. At first, I was wondering if it would be possible to use 2 or more wifi adapters. After, I came to something called Powerline. It looks great but it seems it is pretty much the same speed as wifi(I have 802.11 n adapter). So my question is, what is a cheap solution to get fast speed to my NAS?
