Title:
  0bda:1724 RTL8723AU No WiFi after reboot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After rebooting the system, the wifi is not initialized correctly.
  dmesg lists [   14.132275] usb 2-5: Firmware failed to start

  However, after complete shutdown and startup the chip works just fine.

  I was using 14.04 before and this chip has always been kind of dodgy,
  requiring a kernel module from github for some time.
