As usual the DELL support website will provide you when you try to search for your Inspiron laptop wifi driver with more than seven wifi drivers from all brands with a total size of more than 1GB to download and test for what, for just a Wifi device, and as I remember there is no Atheros one there ! isn't that crazy?

Update, Driver2: I just want to update this post with another DELL Inspiron Wifi device driver with Hardware ID "PCI\VEN_168C&DEV_0032&SUBSYS_02091028&REV_01", so if your device similar to that ID just install this driver.
And If these two drivers doesn't fit your laptop Wifi device, you can check this one, then this one, if you still cant find your driver please write down your Wifi Hardware ID on the comment.
