Windows 7: Dell Laptop - Broadcom Gigabit Controller Not Connected - How Fix?

If it helps, here are the other networking components this laptop has:

Dell Wireless 1397 WLAN Mini-Card
Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller

Someone please explain to me what exactly the Broadcom 57xx Gigabit Controller does?

And how is it different from
the Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller?

Maybe if I fully understand the functionality of the Broadcom Controller I'll be able to better participate in this discussion.

The onboard ethernet died on my Dell 1525 and I needed a wired connection to setup Linux wireless. I was going to open the lap top and replace the card but I found it much cheaper to buy a Gigabyte USB LAN adapter. This evil bay seller has new product and it's the best price I could find for a NIB product, comes with current drivers on the CD.

Ken, that's the wifi controller, the Marvell is the ethernet controller. One physical device for ethernet and one physical device for wifi, different drivers for each.

Thanks MadCrateBuilder but the pressing need is to enable successful wireless connections.

After confirming each device's function it appears that BOTH are not working since a wired ethernet connection fails also, although device manager says the Marvel is "working properly."

I just realized that I have not tried uninstalling and re-installing either device. Will wait to see if that's recommended.

Can the laptop connect to another wireless access point and access the internet/that local network?
As stated in my OP, the laptop's internal wifi adapter and an external (second) wifi adapter both see available access points and connect to them, BUT the connections won't complete and provide internet access.
These screenshots are from faulty laptop I hope. What I see

-loopback adapter is working and uses tcp/ip v4.
-no wired adapter bound to tcp/ip v4 at all!
-no wireless adapter bound to tcp/ip v4 at all!

Yes, from the Dell Inspiron 1545.

Well, guess that explains why neither a wireless or wired connection will complete.

Now...how can I fix it? Especially the wireless?

Did you see the black down array in device manager screenshot!?

Down arrow
In Windows Vista, 7, and later if you see a small down arrow as shown in the below picture next to the device this is an indication that the device has been disabled.

What to do
To resolve this issue double-click the device, click the Driver tab, and click the Enable button. After it's been enabled restart the computer if asked.
