WD Green SSD, slow performance, can't install Driver

I am having performance issues with my SSD, as you can see the drive is running very slow, I would assume it is a driver issue however I cannot install the WD Dashboard software.
The error: “There is no internet connection” stops the installation process from even starting. The PC has a connection with no issues so not sure why it is saying that.

That version, V2.4.0.1, is old. V2.5.0.0 is current. You might try downloading it and see what happens.
