My internal NIC had major issues w/ upload speeds and thus I looked for a quick external hard wire solution.

Windows 10 laptop, with marginal WiFi coverage, but a nice gigabit hard wire jack next to it

Our office has a local QuickBooks server that I need to access via a hard-wired connection

CAN NOW CONNECT TO THE INTERNET BY WIRE VICE WIRELESS.

For the perils of multiple users accessing a local QuickBooks server database over wifi do a Google search on "quickbooks sln41481".Anyway, I'm back in business connecting to our local QuickBooks server via a hard wired Ethernet connection

And every once in a while you need a hard wired Ethernet connection.

I ordered this to have a hard wired connection on my iMac.

I use in on hard wired HTPC set ut and it gives real boost over wifi speed 1gb easy

Once that was figured out, it was very quick to install and has given me back Ethernet on a Mac with a broken E-port
