With the Vero 4k, using a USB gigabit adapter across max 20-25 ft cat 5e, speeds will slow down to ~1MB/s.
After a reboot of the Vero, speeds will go as high as 20-25MB/s but usually will crawl back down to 10-15 average for very large 4k mkv files.
Is this normal behavior?
What kind of tests can I run to determine root cause?
Thanks.
I would not think it is normal. But surely hard to diagnostic.
Would start with then the issue happens to:
grab-logs -A and provide URLifconfig to see any errors on the interfaceDoes unplugging and replugging the adapter help?
Thanks, hadn’t thought of unplugging the adapter and back again.
Wasn’t sure if logs would show anything since the steps always say to reboot after enabling and the issue is resolved with a reboot.
Thanks for the quick replies.
I connected to the vero from my pc using WInSCP and opened a terminal window and ran ifconfig, is that what will tell us something?

Surely this doesn’t look healthy but it might be caused by the USB versus gigabit discrepancy

But still would suggest to check the cables and switch
There’s a hardware issue there, either cabling or adapter.
Thanks, have tried replugging the adapter and also swapped network cables, same performance. The new year will likely see me purchasing a new router - will see if this is perhaps the culprit
I have very poor performances on my Vero4K.
I bought a gigabit USB adapter after reading here other users experiences months ago.
I got an Anker AK-A7522012 but the speeds are very slow.
What tests should I perform, and how, in order to try to see where’s the problem?
is it a Vero problem?
thanks!
No
iperf3
is there a guide?
I’m on a Mac, is there any terminal-based procedure or other apps?
thanks. got it installed on the Vero, but this:
Install it on your other device in your LAN (NAS, Server, Router or PC) following the respective method from here https://iperf.fr/iperf-download.php
that website is not working. 
is there a precompiled app or pkg?
Works as expected, here. 
OK, managed somehow.
I did both tests with and without the “-R” option as in the How To.
first time for me doing something like this so I hope I did it correctly.
here’s the results:

There is clearly some 100 Mbit/sec technology in between or at the remote side.
Could you describe the network topology between the Vero4k Gigabit adapter and the remote site where you also installed the iperf3?
Sure. thanks for helping.
the gigabit adapter goes from the Vero4K into a Netgear GS108 gigabit switch, with a very short 10cm eth cable. both LEDs are green on the port, indicating that the link is 1000.
then a ~20mt SSTP CAT6 cable goes through a couple of rooms, into a Netgear R6300v2 router with gigabit ports.
my macbookpro (2018) where I installed iperf3 as server, uses an usb-c adapter to get gigabit ethernet. I can see on Network Utility app in macOS that the mac has a gigabit link.
the mac adapter is connected directly to the R6300 router.
@bradipo But something is limiting the speed to 100Mbps.
You sure it is a Vero4k+ ? The Vero 4k had a 100Mbps interface.
it’s a Vero4k, not 4k+, but I’m using a gigabit USB adapter
OK. Then your gigabit Adapter does not seem to provide Gbps speed …
