Hi All, searching the forums and the internet I couldn't find anything, so I will post here, before I call Apple. When I have my mac book hooked up to my WD External Hard Drive, I will lose my WiFi Connection. They war I normally have everything connected is through a non powered usb 3.0 hub with my printer, WD external Drive, and one of my samsung DVD drives usb ports in the hub, and the other usb port for the DVD drive directly into the MBA. It is driving me crazy. Any help or thoughts would be very welcome. Thanks!
