Can't upload to usb storage from android

Hi, all. On my Android phone I'm using the genie app version 3.1.52. My x4s router has FW version 1.0.2.46. I have a WD drive connected to my router. I can use the ReadyShare feature of genie to download a file from my USB driver to my phone, but can't upload from the phone to the USB drive. I've used two separate procedures described below and both fail. Does anyone have a solution? Thanks.

Procedure 1:

   1. I click on a LOCAL jpg on my phone. E.g., birds.jpg.

   2. The app displays the image.

   3. I click on the upload cloud button in the upper right.

   4. In the dialog displayed I select my folder. I.e., /ReadyShare/pictures

   5. I select OK.

   6. The "Uploading" dialog is displayed. "Current progess" stays at 0%. File is never uploaded.

Procedure 2: 

   1. With the LOCAL tab showing my phone files, I select the menu in the upper right and then select "Upload".

   2. Check boxes are displayed next to each file. I select "birds.jpg".

   3. I click on UPLOAD at the bottom.

   4. In the READYSHARE tab, I select my destination folder, pictures.

   5. I click on SAVE at the bottom.

   6. An "Updating" dialog flashes then disappears.

   7. Again, the file is not uploaded.
