Hi! I have a new Dell XPS 13 Ultrabook. I also have a seriously annoying issue with said PC. Whenever I connect either my USB 3.0 external hard drive or my USB 3.0 docking station to the USB 3.0 port of my ultrabook, my WiFi connection dies. The system recognizes that there is a wireless network. However, it will do one of two things: with the 2.4GHz signal, it will connect without an Internet connection; with the 5GHz connection, it won't connect at all.
