With iPad Pro controlling Win 7 Pro PC I have no problems with connecting on my LAN. I am also able to connect over an external internet connection (WAN) If my PC is switched ON it is always available to the iPad Pro on the WAN. I can then Suspend or Shut Down the PC. However I then only have a time window of about 5 minutes for Wake Up to work. If I leave it any longer than 5 mins Wake Up will not work. Has anyone any suggestions for this problem ?
