I apologize for reviving such an old post, but I have searched this forum for an answer to this and have had no luck.  I have 3 computers, all on the same network, monitored by Pulseway.  Two of these computers notify me without fail when they wake up, but the third does not.  I get notifications for everything else but not when it resumes from a suspended state.  Does anyone have an  idea what might cause this?  I should note that after it resumes it does seem to take a second or 2 before I can access a website, though wake on lan works everytime.  I don't use hibernation, just standby.
