So that's why a 2 systems were getting crappy speeds. Yes, 2. It had been used only to split a single drop from another switch between two systems.

New drop, happy clients.

Some stuff here is museum material.

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.

Shouldn’t be a grounding issue as you said that you buried it.

It's a 200' cable and the buildings each have their own connection to the power company. I suspect that the earth potential of the two buildings is quite different - I just have not figured out a way to measure it yet and not sure if there's anything I can do to fix it even if I do confirm it.

That shouldn't be a problem unless you're using grounded shielded cable, in which case you should make sure the shield ground is only connected at one end.

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.
