Rebooting 4k to bring up transfer speeds across network

Help and Support Vero 4K / Vero 4K +
21

That’s why @bradipo is using the gigabit adapter Anker AK-A7522012.

Hard to say with that information what could cause this, my brainstorming

  • check QoS on the Netgear router
  • try to verify in other ways that the Anker and the USB-C adapter on the Mac are able to provide higher speeds than 100 Mbit/sec; is the Anker able to provide the speed if connected to USB 2.0, only? Power consumption is different using usb 2.0 and 3.0!
  • the 20 meter cable is connected to the GS108 and the switch should show gigabit for this port

What happens if you power down the Vero4k and directly connect it to the Netgear router in headless mode (no HDMI connected)?

22

the QoS is switched off I think
14

I don’t know. is the USB on the Vero4K a 2.0 or a 3.0? would you say that it can’t reach gigabit speeds if it’s on a 2.0?

I can see both LEDs on the switch showing the link is gigabit. I can also see on the router status that port n.4 has 1000M link (the 20m cable goes into port 4)
03

I don’t think I get this. should I unplug the HDMI from the Vero4K and plugging it directly to the router, so bypassing the switch and the long cable? is that correct?

23

I’m using an Amazon Basics usb gigabit adapter - not entirely sure it’s giving me the speeds as well…debating picking up another one.

Is there a proven model that works with Vero 4k?

24

I bought two Anker AK-A7610011 at Amazon and connected them to a Pi3B and Vero4k … works as expected (you will not get full Gigabit but can reach around 30-35 MB/s download speed). On the Vero4k I get:

I just connected the vero4k via the anker gigabit adapter directly to the macbookpro with a cat6 cable to the usb-c ethernet.
I got the same speeds basically… so I guess this rules out the network infrastructure (router, cables, etc.) right?

who’s the culprit now? the anker connected to the vero or the satechi connected to the mac?
both of them should provide gigabit speeds…
what other tests could I try?

why is that? is it impossible to get real gigabit speeds on a vero4k, then?

26

Did you check if they negotiated gigabit?

27

it goes via the USB 2.0 stack which is limited in bandwidth

28

so, assuming I’ll get a good gigabit adapter in the end, should I just reach something around 300mb/s as in your test?
well I guess better than my 90s…

since there are no LEDs this way, how can I check? just looking at the network utility in macOS I guess?
if so, they did.

Ethtool on the Vero

30

have I done it correctly?

Yes looks right and with that you only get 94Mbit in Iperf3?

32

yes :frowning:
even less than that…

33

Upload logs with grab-logs -A and also post your iperf3 results from this setup

34

should I post the URL here?

35

Yes, and your iperf3 output

36

here’s the log: https://paste.osmc.tv/maconatapu

and here’s the ethtool + iperf3 results on the direct connection between the vero4k and the macbookpro (both with gigabit adapters):

iperf Done.

thanks!

FYI: the two adapters are a Satechi ST-TCMA2M on the macbook pro, and an Anker AK-A7522012 on the Vero4K.

37

Something on your network is limiting you to 100Mbps

I suggest rebooting any switches and routers

38

@bradipo Happy new year!

I assume the Satechi Thunderbold3 thing to be the root cause, here … but you need a third gigabit capable device on which you could run iperf3 or other large data transfer to verify where the error is located.

Low hanging fruit it’s worth to invest a minute:

39

I just run the December update, then I rebooted my router and unplugged the switch.
Now the results are much better, similar to those posted previously by @JimKnopf:

[ ID] Interval           Transfer     Bandwidth
[  4]   0.00-10.00  sec   349 MBytes   293 Mbits/sec                  sender
[  4]   0.00-10.00  sec   349 MBytes   293 Mbits/sec                  receiver

So I guess this is the maximum speed that I can reach with the Vero4K and an adapter? or are there other ways of improving?
And what are the improvements on the Vero4K+ in terms of gigabit speeds? what numbers should I expect, in case I’d be willing to get a new unit?

and Happy New Year everyone! :fireworks::sparkler:

40

That is close to what is possible with the USB2 port.

The Gigabit of the Vero4k+ is internally connected and provides full Gigabit speeds so you would realistically 930Mbit.
