Can I use my Wii to download drivers for a dell laptop

Just go to friend and download only and only network driver, copy it to usb stick and then install on your computer.

after installing network driver you can download all rest of teh drivers directly to your laptop.

you will have lousy display and no sound - therefore download display drivers second and then download intel drivers then rest of it...

as you did not provide model and operating system - only general advice can be given...

for future reference, you need to provide manufacturer, model, operating system...
