|AmyJo, see my response # 2.|
Scroll down to where it reads "Enter a service tag or express code."
Type in the Service Tag from your computer. Most of the Dell laptops have them on a sticker on the bottom of the laptop.
Once you see the system show up, click on Drivers and Downloads and select the option to "Find it myself"
Select your OS from the list if prompted
All you really need to start is the Network drivers (just download and save all of them)
And the Chipset drivers
Once you have the files saved to your Thumb/USB drive, insert that drive into your laptop and just double-click on each file to open it and install the drivers.
Once you install the drivers, you should get network connectivity
After a reboot, go back to the Dell Support page and download any of the drivers that are showing with a yellow Exclamation point in your Device Manager.
You could also select the "Guide Me" and "Detect Drivers" option. That will install a system utility where the result will actually show any drivers that are recommended for your system.
I hope this helps.
