Ethernet Category (referred to as Cat) is the specific standard used by manufacturers when constructing Ethernet cable.The wider the pipe, the more water it can handle. How do you visualize this? Think of MHz as the width of a water pipe. Megahertz, for the curious, is an electrical frequency (take note on the electrical part).
Megahertz is a clock speed measurement of how fast something can go. Then we will put this in a real-world situation so that everyone can make sense of it. Let’s pump the brakes for a moment and start defining what some of these terms really mean. What exactly does this mean to your network? Does higher ethernet cable MHz speed matter when it comes to ethernet cable and its category? Does this equate to higher bandwidth? The answer is not a simple yes or no, as you likely have guessed by now. Written by Don Schultz, trueCABLE Technical Sales Representative & Fluke Networks Certified Technicianįrequently, the ethernet cable MHz speed rating of an ethernet cable is an important checkbox for many shoppers. But when I plugged in my older 4HD and it had the same issue, I knew it was no longer the port.Ethernet MHz Speed: Does It Make a Difference? Can anyone help me diagnose what's going on here? I was convinced thew first time talking to Apple that the ethernet port on the 4K was just bad, so we set up a service repair on it. I've been looking around the Orbi admin login area, and I can't find anything that looks like it could be blocking those, but I don't know if I'm looking in the right area. I do not show an IP or any other numbers on the Apple TVs Network settings. I should also point out that when it's plugged into the ethernet port and the WiFi is off on the Apple TV, I only show a WiFi MAC address. So I talked to Apple support, who suggested the only possible reason could be that the Orbi is blocking its ports that the Apple TV needs to connect to Port 123 mainly, but also 36. So I have ruled out that it's a ethernet cable issue, and it's not a single Apple TV device issue. I have tried multiple cables (CAT5, CAT6) which will work connecting other devices, like my MacBook or whatever, but they refuse to connect to the Apple TVs. 
However, I cannot get either one to connect via ethernet. Both of these Apple TVs will connect to the WiFi with no issues. I have an Orbi mesh system and two Apple TVs (4K and 4HD versions). Sorry to bring up an old issue, but I'm having these same problems with my setup.
