I've been looking for an answer to this for a very long time. perhaps someone here knows the answer. I has a WB Mybook drive. It is hardwired on my network. It has several shares set up and these are mapped as drives by a number of Windows 7/8 pc's and linux servers. This setup has been working perfectly for nearly three years. Then I tried to use the same mapping setup with a wirelessly connected Windows 7 laptop. It will not map the drives, sometimes it tells me the WD drive does not exist, other times it prompts me for username and password for the share owner. However nothing that I enter works and it goes into a loop prompting me. Funny thing is, if I plug the laptop into a wired connection, the drives map and function perfectly. I finally gave up and didn't try anymore, until we added two more laptops to the network. Same thing happening, on both Windows 7/8. Also on both of these laptops, if I plug them into a wired connection everything works just fine. Any thoughts?
