i will try. but sometimes i reached the 300 mbps with a warm devices.
vero in the fridge? 
1G - all between 25-300 mbps
100 mbps - 100mbps
back to 1G - all between 25-300 mbps
:-p 
no one with a Vero in bed ? :)- ;-p
worst result so far:

Too hot IMHO. Mine rarely goes over 55C …
70 is perfectly fine.
In May or so we stress tested heating the device up to 110C+ with iperf3 and kept the speed constant.
It sounds like clock drift. I’ll try reproduce
Same problem over here. 4K+ received today (#20007). When Ethernet is plugged in to a Netgear GS116, I get the following:

Let me know if there is anything I can do to help.
So if your device is cooler it performs better too? That is odd.
That remindes me the raspberry PI WiFi Dongles I have. When they overheat - I loose throughput. Lots of it …
The thing is we had this issue in May where heat caused the TX to completely tank. This was caused by calibration issues with the PHY. Since then after some changes, we weren’t able to reproduce this.
There are a couple of devices I’m seeing:
- Completely borked TX: showing about 1-2Mbps
- TX that seems to be better, but still not quite right.
Still investigating, but in the interim we are swapping with known good units.
We’ll work it out.
Cheers
Sam
@sam_nazarko What is your ETA on having an RMA system for getting a warranty replacement device free of charge without incurring any costs for the customer? In an email you said “a while”.
@sam_nazarko just to let you know that I have now received the new device, and the performance is looking much healthier!

Hi,
I think I explained this to you via email yesterday; apologies if this wasn’t the case.
We have to apply for a business response license in every country; which takes a while. This will also allow us to provide simpler returns for customers in the future if they change their mind and would like to return their product.
I don’t have a firm date yet. But we have replaced all units received back to us so far. I will ping you when this is ready on the original ticket. It won’t be long.
Cheers
Sam
Thanks for confirming. I’m glad you now have a device that’s working as expected. @Nightcustard was also kind enough to confirm that his replacement device is now working as expected.
We’ve stopped the possibility of dodgy devices shipping now; so this should be wrapped up shortly.
Cheers
Sam
Hi,
No you just replied that it will take a while. I hope it won’t take an unreasonable time.
No – it shouldn’t take too long. I am still waiting for the response license in Finland to go through.
I just want to add a comment here. I dont have these problems but still only gets around 400-600 even with a new CAT6a cable.
However since its another problem and also it runs everything I need atm I will lurk in this thread and maybe test a release now and then.
I havent even received my 4K+ and ive been lurking here for days! 
In both directions? just curious.

Mayybe its a little faster the other way, but not alot. Not near 900+
