I've been revamping my network and I just noticed a very weird behavior from my Mantiz Venus: If I am doing a network intensive load for a long period of time (e.g. moving ISOs from my laptop to a network share, or downloading something like Doom Eternal) the entire network would lock-up and stop responding until I reboot the laptop. Not sure why this happens, or if its something common with the Venus. I have tested this through a separate Ethernet USB adapter and the same problem occurs - I'm thinking that this may be related to the USB signal.
Any ideas on how to fix this type of bug?
The current workload I'm facing issues with is downloading Doom Eternal from Steam to an SSD within the Venus enclosure.

Hi,
Β
I've got the exact same behaviour. If I try to stream a game over Steam for instance. Hoping for an update of the driver soon.

Have you checked with other high speed USB Devices?Β (Like a hard drive?)
That way, it may help to narrow down if it is the USB Controller.
My 2018 Mac Mini's network link would disconnect, requiring a full shutdown before starting back up. Turned out the NIC was overheating. When it happens, try loading up the Event Viewer app, look under Custom Views -> Administrative Events. Scroll through the events and see if you can find an error at the appropriate time. Mine would identify the network adapter and explicitly say something like 'Overheat detected! Please power cycle the machine.' Apparently this was a common problem with Apple's 10 Gbit network interfaces, which I suspect explains why they don't have them on the M1 Minis... Only ever happened in Bootcamp, though.
Of course, if that were the case here, it would seem weird that it would happen with a USB NIC as well. So perhaps it's some other component, but my guess would be overheating could be the culprit.

.My use case for the eGPU is for a Windows / Boot Camp install. Mainly because right now I'm with a 2080 in the eGPU.

I have yet to test this exactly. My exact behavior right now is when I'm trying to copy files over an Ethernet link (whether is an external USB adapter or the actual Ethernet adapter built into the Venus) to a USB drive plugged into the Venus as well. My theory right now is that the USB controller within the Venus may be overheating - I do have an extra Noctua fan (NF-A4x10) that I will slap in the eGPU with a Y-splitter with the actual case fan. Will try over the weekend and see if this helps solve these problems.

@teltersat2, Best of luck on this attempt!Β Whilst you're at it, you may also want to try putting the hard drive on another USB-C Port on the computer (rather than both on the same Venus).
Β
The rationale being that it might be the case that the data flow is Ethernet Link in Venus -> Computer -> USB-C Hard Drive.Β In that scenario, the data pipeline is more streamlined than:
Ethernet Link in Venus -> Computer -> Hard Drive in Venus on the same cable
(Similar effect than using an eGPU with an Internal Monitor yielding bad performance, compared to eGPU using the External Monitor)
Β
Of course this is just an idea.Β Might be the case the overheating is the root cause!

I thought about this too - but honestly, what's the point of having these features but you can't use them as intended because of these issues... Wish Mantiz could have an official word on this...

@teltersat2, wholeheartedly agreed!

Welp! this was an adventure! it seems that I plugged the main fan into the WRONG header, and fans did not spin at all, but when I connected the small NF-A4x10 fan to the other available header, I was surprised that this was the only fan that spun. Looking at some release pictures and details from the Venus, I discovered my mistake... Now I can copy with no issues whatsoever.
In summary, yes - Issues were related to thermals, but they were of my own doing!
