WD Smartware for Backup to EX2

take a look at this topic, maybe you will fin some answers: http://community.wd.com/t5/WD-My-Cloud-EX2/What-to-do-to-increase-transfer-speed/m-p/847195

so I will take a guess here that you EX2 is connected via ethernet cable into your router. From what i saw at a first glance is that it has gigabyte port, but not sure if it’s using it. To your router you are connecting the computer via WIFI.

  1. are your wireless board’s drivers updated ?

  2. are you using b or n or ac type ?

  3. what type of encryption does your router use for wifi and have you tried changing it ?

  4. are you using 20ghz or 40ghz  and have you tried changing it to see if it helps ?

  5. are there other computers on your network and is the speed the same ?

6.what’s the distance between your router and computer and what interferences do you have?

  1. are there other wifi channels in your area the same as you are using ?

  2. what HDD configuration are you using in the EX2 ?

  3. does the speed improve if you plug in the EX2 directly into your computer ( to rule out the writing speed on the nas, or software limitations) ?

so you see, not very easy to pinpoint the problem
