Hello,
My wired network speed is ~940 Mbits/s. But the network speed of my new vero4k+ is to slow to play UHD ripps (50-80Mb/s). Browsing network shares is slow too. Iperf3 shows only ~30 Mbits/s.
The switch the vero4k+ is connected to shows a gigabit connection and my old nuc connected to the same switch runs 930Mbits/s. Is there a setting or a config file to edit?
Is there a built in factory hardware test?
Just to confirm: you’re connected via Ethernet?
Can you show me the iperf test output.
Sam
yes, the connection is via ethernet. Here are the iperf3 results. First to the nuc on the same switch, second to the windows fileserver over two switches. Third is windows to nuc over two switches.

Sam
i totally forgot i am using the vpn addon. But on the other hand it should not matter as the nuc is running it too. But i try with the vpn disabled first, ok? If it does not help i upload the logs tomorrow (later today) as i have to climb the stairs up and down all the time and my family is already sleeping.
Please try with the same Ethernet cable as the NUC and VPN turned off. If you let me know your order # I will test with a QA unit from your batch
Sam
Tested with vpn off and swapped network cables, same results ~30Mbits/s.
My order number is 18869, from July 22, 2018.
Thank you for your support, but it’s late now and you should enjoy the weekend. Let’s continue this later if you like or next week. Good night!
Suggest to install ethtool and check the negotiated speed
I’m investigating this now with a device from your batch.
I took a device from the batch you’ve received.
Updated it to the latest version of OSMC.
I then took a different device from a different batch.
ethtool eth0 shows on both:
Link partner advertised pause frame use: Symmetric
Link partner advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: MII
PHYAD: 0
Transceiver: external
Auto-negotiation: on
Supports Wake-on: ug
So I have 1Gbps negotiated when connected to my local switch.
I then ran iperf, using a window size of 1MB.

I changed the cables, ports and powercycled the switch. Still same results. After installing ethtool, it looks like the pause frame use is different from your device. There is also a problem with wake on lan.

Meanwhile i uploaded the log to https://paste.osmc.tv/amohupiwiv
The setup is still basic osmc, updated to 2018-8.2, with the service.vpn.manager addon (disabled for now). I installed iperf3 and ethtool via apt. IP of vero is 60, the windows fileserver is 51. The vero is connected via HDMI and analog to my receiver. The wired network is connected to a 8-port Gigabit D-Link desktop switch with a cat 7 cable. To controll it i use the osmc and a harmony remote (which is much slower 
). The ir receiver is in the black usb port.
The device doesn’t support Wake on Lan.
I will look at your other issues shortly
Sam
I have iperf server running on MacBook (5GHz wifi).
iperf client running on Vero 4K

Vero 4K+ ethernet is more than 2 times faster than Vero 4K ethernet.
The bottleneck here is the WiFi link to the MacBook.
(probably if MacBook was connected with ethernet, then Vero 4K+ would show 1 Gig speed)
With ethtool, it looks the same as yours:

Hope this helps.
That’s quite slow. Are you testing to a WiFi connected device?
Edit: just read that you are.
Ok, just connected iperf server (MacBook) with ethernet (192.168.1.185).
Vero 4K+ iperf client shows 1Gig:

The first is that the difference in pause frame use between yours and Sams is a difference between your switches not your veros…
Sams says “Link partner advertised pause frame use: Symmetric” which means his switch is saying it supports both receiving and sending pause frames, while yours says “Link partner advertised pause frame use: Symmetric Receive-only”, which means your switch is advertising that it will honour any pause frames sent to it by the vero, but won’t send any pause frames to the vero.
This is nothing to worry about, and is not related to your problem.
The next thing is that I’m not sure you’re aware but the iperf tests you have been running are testing the sending speed of the vero, not the receiving speed. The iperf client sends, the server receives.
To test the receive performance you need to run the iperf server on the vero and the iperf client at the other end. Can you please try that so we can see if the issue is in both directions.
Other things you could try to help narrow down the cause - can you try an iperf test in both directions between vero and nuc on the same switch ?
Also is it possible when testing your vero to server performance to temporarily plug the vero into the same switch as the server, rather than going through two switches to get there ?
Also another thing to check if the switch the vero is plugged into is a managed switch is to check in the switch’s web interface whether any “rx errors” are reported on the port the vero is connected to ?
If you find a page that shows that information, zero the counters, perform your iperf test then let us know how many rx errors you see, if any.
Finally, what model are the two switches ?
That low transfer rate and high retries suggests there’s a link problem.
Probably that is why the initial setup and update for Vero 4K+ was taking so long and not succeeding.
I think the problem is not with Vero 4K+ or its ethernet port.
My suggestion is to troubleshoot the physical connectivity (cabling) and then the network connectivity (switching).
thanks for clarifying the “pause frame use”.
I tested the vero as as iperf server

thats odd. If the vero can recive ~1Gbit, why does it not play a 80Mbit movie from the server? Its buffering every 10 seconds or so.
Both switches are 8Port 1Gbit D-Link desktop switches, not managed. They are on different levels but i will try to connect the vero to the server switch.
