Review on Cable Matters Snagless Cat 6 Ethernet Cable 20 Ft (Cat 6 Cable Industrial Electrical for Wiring & Connecting by Josh Andrews

I strongly doubt the statement "Cat6 performance at the price of Cat5e but with a higher bandwidth". And in this case it's obvious that either the QC is bad or it's more likely not a Cat6 cable. The cable ran at a maximum speed of 50Mbps and had a lot of buffering issues. Just get a cheap old cat5e from a reliable supplier and go.
