Hi Jerry,
Are you missing the "Link Speed" tab, but you can see the "advanced" tab on the adapter properties
I'm not sure which board you have, but I can direct you to the latest generic drivers:

When you run the download package, make sure you install PROSet (and ANS) depending on what properties tabs you want to add on. You only need Advanced Network Services for configuring VLANs and teams, but PROSet is handy for the help files and diagnostics that you get by adding it.
You could try doing an uninstall on 17.4.95.0 before loading version 18.3.x.x. On the other hand, if 17.4 is working well for you , you might want to just stick with that version.
I just installed 18.3 on the laptop I am using now. I have PROSet installed and I get the "Link Speed" tab that is added by PROSet. My device is the 82579LM, which is very similar to yours. The installation package should be working unless some other software (security?) is interfering.
