That would be incorrect. After the unit was returned and examined it was the ethernet port on the controller had an intermittent issue. It was actually bent sideways and was causing thousands (yes thousands) of "resend requests", which are an indication of a poor connection. This also explains why a single line command would execute flawlessly but a streamed file would not.
After the controller card (Beagle Bone Green) was removed it was obvious that the LAN socket was bent sideways in the direction of the cable entry gland nut, which is usually evidence that the cord had been jerked or tripped over. In any case the LAN cable had been pulled against the strain relief hard enough to bend the socket and cause intermittent connection issues. A simple replacement of the BBG solved all the issues.
That controller was resold as "an open box" at a discounted price and has been cutting parts in NC for over a month without issue.
I would like to take issue with Jerry Stanek' and his "professional victim" postings. This was a well made inexpensive product, (Acorn Basic model) a product that costs much less than what he could have purchased from the OEM mfgr. And it performed flawlessly, lowering his noise, increasing his speeds beyond what the OEM recommends with those motors. And he bragged about it here:

Then apparently he tripped over the cord and it all went away..... and since then has been whining like a child.
Jerry Stanek.... THIS WAS YOUR FAULT You jerked on the cord. You were allowed to return the controller for a refund. Get over it and shut up, this whining a couple months after you received a refund makes you look like a fool.
