I’m testing a unit as we speak.
I need to get a known affected switch from a user. This is in the post. Many switches vary internally however due to revision changes. I want to ensure I get a switch in my hands that have been tested and confirmed as problematic by a customer. It’s not a sake of saving £20.
It’s going to take a few days to resolve. If this isn’t satisfactory, I suggest you return the unit for a full refund.
Cheers
Sam
I appreciate the response.
It’s good to get some more info on the matter and that a defective unit is being actually being tested.
Really appreciate the offer of a refund as well, but I’m happy to wait and see if it can be solved by a software/driver update.
Also can you confirm that you have noticed that myself and other users have the slow network issues (wired) even when we don’t use a switch ?
So you have tested a direct cable connection from your Vero to a PC without going through any switch ?
Or do you just mean you are plugging directly into an ISP’s router ? If the latter, a router with multiple ports is still an ethernet switch to the devices connected to it…
Sorry I stand corrected.
I haven’t tested Vero>PC no, I wouldn’t know how to set this up and test it.
So yes it still went through my Asus 68U router and therefore it’s switch 
Oops 
Crossover cable and give both a static IP I’d imagine?
Most Gigabit Interfaces support auto crossover (so normal cable good enough)
Hi,
I cross over cable shouldn’t be required (most network equipment can now transmit and receive on the correct pins with a standard cable these days), but yes a static IPs on the PC and the vero would the be easiest way to do it.
Thanks Tom.
Shows how long ago it is that I used a crossover cable 
I did test my vero 4k + connected straight to my synology nas (with the nas setup as dhcp server) and only got a bandwith around 6 mb/s so that did not make a difference.
Hmmm…
Could those having the issues here please tell us what NAS they have?
I could be wrong, but I see very often Synology.
Anyway, I bet that as soon as Sam can replicate the issue, he’ll find out what’s going on anyway.
WIn10 machine. So nothing to do with Synology.
This is what I get -Vero4K+ direct to Win10 PC, cable is newly bought Cat.7 (PIMF). With my Router (Mikrotik hAP ac) I get much better results, only Tx is affected 350-600 Mbits/sec (600 is when I use 0.5m cable lenght, instead of 10m which I need for Vero)

My NAS is a WDMyCloud 8tb, but that’s irrelevant to my issue as I’ve tested Vero>Router>PC
Vero>Router>Laptop
Vero>Switch>Router>PC
Vero>Switch>Router>Laptop
All with the same dismal result.
This is puzzling. I tested exactly this switch model & revision, and it certainly had the slow speed problem. I assume you have updated it to the latest firmware?
The only switch not causing slow speed was the the Atheros chip in the Mikrotik hAP ac2 and the CCR 1009.
So it really must be a combination of unfortunate events. Voltage? Noise?
Thanks - that is very useful to know. Yes it is running the latest firmware:
It’s actually my main switch at home in my TV cabinet, in addition to the 4 port switch built into my Superhub 2.
Can you post the iperf3 results when testing with the TP-Link switch, and how does it compare with other switches showing the same issue ? About the same or worse/better ?
I hope you are sitting. Because I just tested the Switch and it actually wasn’t so bad. Even Billy Lynn HFR HDR played:

Strange. Could I be so wrong? Then I connected the Vero to a different port (7, it was on 2).

This is crazy!
EDIT: Switch type, revision & firmware is same as yours. All ports are dumb switched, Flow control off, auto negotiation, no VLAN.

Must have been be a coincidence. Vero back on port2 is bad. As expected. But maybe it is temperature related? Voltage?

Hello all,
Yesterday I received my vero 4k + and after initial setup I started mounting my Synology NAS via fstab. The vero did indeed mount my NFS shares but then the problem started. First of it was real slow reading the shares but worse; it would not play any movie but just froze up. This was all on a wired connection through a switch. I tried rebooting everything (router,nas,vero) but still no joy. I checked my raspberry pi with the same fstab setup and also wired on the switch and it played just fine.
I connected the vero straight to the router but it kept freezing up or just keep loading any movie I wanted to play. Getting a little bit desperate I started to tinker a bit with the fstab file but knowing not much of Linux I kinda of messed it up and decided to start fresh and I reinstalled Kodi through the OSMC installer also hoping this would resolve my network problem. Sadly this was not the case. So i turned to the wireless connection an to my surprise everything was working perfect. Really fast and responsive.
So now I’m beginning to think that I 'm having a problem in my network. Today I bought a new cat 6 network kabel and tried again connecting the vero straight to the router and unplugging everything else besides my NAS. But again the very same problems occurred.
I am now at the end of my wits. I read on the forum that an Iperf test wil come in handy for this so I am trying to google my way into this because I am not familiar with this but I think I’ll manage. So let’s see how far I get with that. In the meanwhile I will provide my logs in the hope someone can figure out what’s the problem or if there’s something I am just missing. Any advice will be most welcome.
Hi,
Have your tried restarting the router?
Results of iperf3 would be interesting as well, few things things to try.
I suggest connecting a wired device running either windows or linux and issuing the following command:
iperf3 -s
Then from the vero4k+ connected to the switch issue:
iperf3 -c ip.of.device
I suggest repeating the above with router connected directly to the router.
Also could try reversing the tests aswell, on the vero:
iperf3 -s
Then on the device connected to the router:
iperf3 -c ip.of.vero4k+
Thanks Tom.
Are you using a powerline adapter?
