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.

That thing isn't even old. I had a similar situation occur recently. I found a 10meg 3com hub two months ago. Not 10/100 but 10meg. Not a switch but a hub. It was in a closet between two fairly new switches. I just chucked it not thinking it might be a conversation piece. We replaced the line with a 50m fiber run. We also replaced several drops since they were thirty years old. The customer was really happy with how fast things are now.
This one must be about 15 at least. Pre-dates me and I've been there for 13. Still functional so I'm at loathe to just sling it. Not fond of doing drops in such wonderful weather, in a building that is basically a dusty hot tin can. Wanted to do it properly though.
Just happy that on this side it's my direct employer and only one site. I'll have to do some more digging - I'm certain we have kit around even more legacy than this. The CNC lathe PC is y2k compliant....
That 3com hub was new in the late 90's
At least the lathe isn't running punch tape.
Don't upgrade or mess with the control. Disconnect from the network if it's on it. It should have RS-232. Throw a Pi or other SBC that does serial and a 12V level shifter; use that to feed it programs.
Also, make an image of the hard drive if it has one and start looking for a spare drive on ebay.
I've got it covered :) - whole duplicate set of hardware & drive image. Recapped the board last year & replaced PSU too.
I won't touch the DOS software it uses to actually run the plant, the lads can have at that.
Rock and roll. I've seen bad things happen when someone decides it's a good idea to modernize a PC based CNC control. (I hate PC based controls). They get their own little fence to live inside where it's always 1999.
