Summary: Was very disappointed when I opened the packaging to see a huge warning stating "do not install with out CD" searched packaging (just an envelope) for CD... None to be found... Receipt plainly states adapter only / no CD. Scoured the amazon page for this product and in way does it indicate driver not included. Can't even download the driver this is an Ethernet adapter..
Summary: I have an old Dell d430 running as a router with pfsense and am using this card for a 2nd NIC. works perfect out of the box and was recognized by pfsense right away with no trouble. With this I now have a router with battery backup so if the power goes out, my net still stays up.
