LNE2000 - Ether16 Combo LAN Card. This the correct driver card for the chipset "004005-3C7240". The card is labeled "Linksys Ether16 LAN Card." The chipset is also labeled as "Delta". However it is the correct card for this adapter. It has a a BNC and an RJ-45 plug-ins. The first file is for Windows OS and the second is for NON-Windows OSes. Took me a while to find this damm model #. I figured that while I found, I don't any other folk(s) to have a hard time like I had. Good luck! Hope this will help some of of you all.
