QoS is an option in the NB9W but is NOT enabled by default.

  3. Tick Enable QoS, click on Next.
  4. Continue clicking on Next until you reach the WAN Setup Summary Screen.
  5. Click Save.
  6. Click Save/Reboot.
  7. When rebooted, QoS will be fully enabled, and the QoS menu option will now be displayed under the Advanced menu.
