    Is it possible to force 100 megabit ethernet via Windows? This network is technically gigabit-capable so that's what gets autonegotiated, but the gigabit connection is unstable, to say the least, whereas the 100 megabit connection works flawlessly.

    You can force it in the advanced properties of the driver control applet. If there are problems with autonegotiation after that, also force it at the network.

    But, you really should not be having any problems unless one or the other is really off-brand. What you may be having trouble with is the auto-negotiation of duplex. Try forcing that first. Or, if it is already forced, then enable auto and retry it. Don't take a chance. Reboot between configs.

    you can change the duplex in the driver properties. but if you do that i think the network will stop functioning. better leave it as auto negotiation.

    I'd try swapping the cable around on the switch/router port and testing the cable. If it's flaky, that's probably where your problem is, particularly if the machine you are using to do the test works okay elsewhere. If you aren't sure, test the box somewhere else, first, then check the cable and or port the cable is plugged into.

    It's the cable for sure - the cabling is ancient and dates back to around when fast ethernet was first standardized in the 90's... Who knows what could've happened to it in the 15 years since then.

    The problem is that the cables run through the wall and flooring, so replacing the cables would require a several thousand dollar renovation.
