Network cable unplugged Intel (R) PRO/100 VE Network Connection

This message is at the bottom right of the taskbar with a red x thru it.

This is on the downstairs computer (the one w/o the router) the one with theUSB Network adapter.

I believe the message I'm questioning is referring to the internal card and is irrelevant. Am I correct.

Thanks. Trying to get everything working totally correctly.
