HR21 show connected to network ok DOD working great! D* power-line sofware finds HR21 Windows updated media player 11 does not show HR21 in media share box! I have trend micro security software and all firewalls including windows are off? I am not super computer savy but could be talked throu. Where do I start to troubleshoot.
