To be honest, I’m not an expert, but here’s what I’m seeing:
I would look into this first. It looks like you’re losing packets at home (even 1 packet loss in a home network shouldn’t happen). Your latency in your home network is also all over the place - 38 ms to 919 ms.
Are you running wired or wireless? If wireless, plug it directly into your router and test it again. If you get different results, then its your wireless connection.
If they’re the same or similar, then the culprit would most likely be your router, possibly software on your computer, or both.
** Edit: **
It could also possibly be another user on your network that’s hogging your bandwidth. Its pretty hard to hog up 68 mbps, but its possible (torrent sharing is the first thing that comes to mind that can do that).
