Ubuntu network connection issue – resolution

Microsoft Windows’ Intel network adapter Power Management setting “Wake on Magic Packet from power off state” seems to cause this issue. Disabling it seems to allow Ubuntu to access the network, following a restart from Microsoft Windows.


  • Start Microsoft Windows
  • Open Device Manager
    • Start > Control Panel
    • System and Security
    • Under System, select Device Manager
    • Note: Administrator permission required–if you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
  • In Device Manager, expand Network Adapters, right-click the adapter, then select Properties
  • In Properties window, select tab “Power Management”
  • Clear checkbox “Wake on Magic Packet from power off state”
  • Select button “OK” to save and exit

Note: we first installed the latest drivers via the Intel Download Center: . Namely, as of this writing: Network Adapter Driver for Windows 7*, Version: 20.4.1 (Latest), Date: 10/2/2015 . You may or may not need to do this, to clear the setting listed above.

Our setup: Dell Optiplex 9020 MT (i7), Intel i217-LM network card, dual boot of Microsoft Windows 7 and Ubuntu 15.04 (both 64-bit).
