I have a brand new Vero 4K+ delivered about a week ago. On WiFi, it stutters immediately on both 1080 and 4K content (480 is fine). After initially pressing play, it will play a very choppy picture for about 6 seconds before freezing. It basically looks like someone hit pause but didn’t. If I wait, nothing happens. It’s just stuck. If I press pause for a few seconds, it will play smoothly as it should for about 68 seconds, then stutter, then “pause”. Vera is sourcing a local wired Windows server box (smb shares) and is connecting to a Ruckus R510 WAP on AC that’s about 15 feet away. The kids beat the crap out of the WiFi and it doesn’t blink an eye. FWIW, Kodi on an i5 NUC on Win10 connected the exact same way in the exact same place playing the exact same content plays perfectly and this isn’t one particular mvk file, it’s all of them that are above 480. So does a 4K Firestick on Kodi for that matter. The Vera will play everything without issue IF it’s wired and not on wireless.

I’d love to get this fixed if I can. It really needs to be on WiFi.
Thanks!

Do you have separate SSID for 2.4 and 5Ghz?
No. They’re combined to keep life easy for me. I’ll look into iperf3
Then there is no way to ensure the Vero is using the fast one
You’re probably on connecting on 2.4Ghz instead of 5Ghz, which is causing the issue.
Okay cool. Thanks guys. I’ll force it to 5Ghz tomorrow and see what happens
Updates:
The wifi is 5Ghz only now. I have tested more files and it’s actually anything that has DTS-MA or TrueHD audio - not specifically 1080 or 4K video. Though few and far between, if I find a 1080 mkv that isn’t DTS-MA or TrueHD, it plays fine. I removed the network from Vero, rebooted, added the network, rebooted, and tried again with the same results.

iperf Done.
The connection doesn’t look stable enough to stream 1080p, let alone 4K video.
Maybe try a different channel on the 5GHZ spectrum. Different channels use different power settings. I had to change to ch 149 to get reliable 4k streaming.
Thanks, Sam. So that I know as this is my first time using iperf, is that observation from the variance in throughput? Any guess why this is the only device that has an issue on the same networK?
I’ll play with channels more when I have a few. I tried isolating to 149 with no change but maybe I’ll get lucky and hit the drawing with one of them
shammond127:
variance in throughput
Well Variance but also the Average 29Mbit would not be sufficient.
Check channels with a tool like wifiman that shows you how many SSID’s on each channel and you can check the signal strength at the place of the Vero.
On my laptop sitting exactly where the Vera does, I’m averaging about 208 Mbit to the media server which I assume is more where I want to be so yeah, something is up with the Vera or the way it’s connecting to the WiFi. Thanks for the comments and suggestions!
