After much work over the last 36 hours, my wireless network is now working but not the ethernet connection on my Dell latitude D600 which uses a Broadcom 4306 card. Any ideas on why this would be?

I see from your other postings that you are probably waiting for Dr Chili to arrive, but for now your ethernet card is not even showing up in the listing above. It really should show something like this thread

Could the card have come loose by vibration (dropping) or actually failing. If anybody can solve the problem Chili555 can!

Hey, you're doing perfectly well.

My thoughts exactly. I'd also like homeuser1 to verify that it's enabled in the BIOS.

Sorry for the slow reply back. Anyway, I checked the bios and can't see where anything is turned off. I still don't have the ethernet connection. For a few hours early in this troubleshooting process, all I had was the ethernet connection until everything was gone. Eventually, Chili was able to bring the wireless network back from the dead.
One thing to add since then, yesterday when I turned my laptop on after being off all night my internet connection was gone. Also, the broadcom driver wasn't showing up in the additional drivers list. I restarted the laptop and the wireless connection came back to life. Today, I didn't have any problems. Upon startup, the wireless connection connected right way and I was off doing my business.
So, I'm back to trying to get the ethernet connection to work. It's not a big deal though. As long as the wireless connection is working, which I prefer, I'm in good shape. Any ideas on what's going on?

When the ethernet is working, does it show up in the command you tried earlier

lspci -nn

If so, it really could be just an intermittent connection (made after heating up a bit) or a card that is failing, but wait for Mr. Terminals response.

I think bkratz is right on track. If it doesn't even appear in lspci -nn, I'm not sure we have any way to fix what we can't see. Does it appear in:
sudo lshw -C networkI think there is a real possibility it's defective.

I think in post 37 of the thread below, Chili brought the ethernet connection back to life. However, after closing the laptop for a few hours the ethernet was lost and has been gone ever since.

Anyway, here's the output requested.

Looking back at the two pages prior to that particular posting Dr Chili was trying to get the b43 driver to work on your system. That would not have affected the wired connection (different drivers). It really looks like that was just a chance happening.
