Hello
I have just gotten an old airport extreme that was dead from a relative. I have removed the N wireless card from it and inserted it in my Dell laptop. It recognises the card but has no drivers. Any suggestions?
Thanks!

Go to the card manufacturers web site. They should have the drivers that you need. If they should be available since the card you have is "N" capable it is probably not very old. Even if the card manufacruror is out of business the drivers are most likely available, but it will take some digging. Try useig your favorite search engine and typing in the name of the card, this should lead you to what you seek

I am not a Mac user but I think that device is for Mac's only.
