Rating: 5/5 Ethernet Adapter July 26, 2018 Something blew my ethernet connection on my computer--think it was lightening. I decided to try to substitute this USB adapter for the original connection. I plugged it in and presto! was back on-line immediately. It works very well with little installation difficulty. Would highly recommend.

I would recommend this item to a friend! Customer Videos:
