Can't access my cloud

Every time I turn on computer, I can’t find my cloud 4tb on net work. I have to refresh it for many times. Sometimes, when I was transfering data to the drive, My cloud could suddenly disappeared on net drive. I have been frustrated about this product. This must be the worst wireless drive that I have ever used. 

Today, I remove the device and reinstall the drive. I found that I can’t access my cloud. I turned off the password. It said that I dont have permission to access this drive. It’s really ridiculous that I was not permitted to access to my own drive… 

This will be my last WD wireless drive
