Good to know. We will see if the router can do a test. If it fails if we unplug it then it is making the whole trip. Or we can get two of these routers.

We had exactly this problem when the 450 APs first came out. They would link up at 1Gb even though there was only a 10/100 injector in between and obviously only two data pairs in use. Cambium later turned on the feature in their PHY that detects if data is actually present on all four pairs or not and adjusts negotiation accordingly. And that was talking to MikroTik ports, BTW. So no, I don't think you can rely on the "does it show linked at 1Gbps?" test. Also, I don't think Josh's suggested MikroTik bandwidth test using a single router will work. If you run a speedtest to itself, it will only go through the CPU. Just sayin.

You'll see link, one color is gigabit. Hell you could run a script to check the rate and print it. For more testing you could do a MT speed test between it/to itself.
