Friday 11th January 2013: 5.46am. Been up to 12-12.30am after work every night this week trying to figure out this packet loss problem, despite that every utility I ran didn't show any unexpected packet loss, and it was really, really bugging me. Just nailed it ... it was the laptop-mode daemon putting the internet NIC into power saving and not waking it despite substantial traffic. Some system update must have changed the behaviour or broken a bridged traffic detection routine ... anyway it's 12.45am and I have work tomorrow! But nailed it, thank god, thought I was losing it!
