I have seen many posts about VERO4K+ Network Speeds… Below is the output from my Vero4K+. If you are experiencing any slow network rest assured that it’s not your Vero 4K+ and it can be a cheap switch, Router, faulty network cable.

With a cheap CAT-6 network Cable:

osmc@MBRVero4Kplus:~$ ethtool eth0

After I replace my network cable with shield CAT-6:

A: You are, in effect, arguing “My Vero 4K+ is not faulty, therefore every other Vero 4K+ in the world is also not faulty”; this makes no sense.

B: From your description, there’s a chance your Vero 4K+ is faulty.

Only a chance, of course. :slight_smile: It depends on whether the first network cable is actually defective, or merely cheap. Clearly no device is going to work well if you connect it to a defective switch with a broken cable; but if the switch and the cable are within the Gigabit Ethernet spec, and a device doesn’t work with them, then the device must be out of spec. If something only works with a special, cherry-picked cable, that’s a bad sign.

It would be instructive to connect a couple of other devices to the same switch with the cheap cable and see if they hit proper gigabit speeds or not. If they also require the second cable to work correctly, then obviously the cheap cable is just knackered, and you’re good. But if other devices are perfectly comfortable with the cheap cable while your 4K+ isn’t, then the 4K+ is quite likely out of spec. (Not definitely, but quite likely).
