As someone who grew up with 10Base2 and 10BaseT, and thought 100Mbps was amazing - it still surprises me every time I'm reminded how slow it is now. I buried a cat6 cable out to my wife's studio and due to (I assume) some grounding issues it only syncs at 100Mbps - it works for general browsing etc., but every time we try to move some data it's arggghhh.

What type of cable did you use? Water could have seeped into which cause a bunch of weird issue because the resistance on the wires goes all wonky. I’m not sure if you have access to a cable certified like a Fluke, but if you do I would use that to test and it will most likely tell you your issue. I highly doubt it’s a grounding issue because you’d issues like that in large buildings where the power is on different phases or technical power.

It's pre terminated pure copper direct burial cat6 from Amazon. I don't have access to a real tester, but my cisco switch has some built in test capability and I'm not sure I fully understand the results, but it's assessment of the cable length is pretty close and, more importantly, it shows all the pairs are the same as each other. I think that if there was some damage to the cable, it's unlikely that it would affect all the pairs in exactly the same way. I have other weird grounding issues - like 20V between neutral and ground, even though it's a new house and they're properly bonded at the service entry. I had a really old transformer on the street feeding the two buildings and the power company recently replaced it - I was disappointed when this didn't resolve all my issues.
