In the network settings, I don’t have the option to choose from wired/wireless connection. Although I had that option the first time I used the device and I chose wired. Now I’m trying to connect it to a wireless connection and don’t know how to have this option back again.
If it’s not showing a selection for WIRELESS, then the WD isn’t recognizing your USB Wireless adapter.
You could try resetting to factory defaults if you are sure that the wireless adaptor is not at fault.
