Recently, I had to restore my Dell laptop back to it's manufacturers condition. Now I am unable to connect to my wifi. My wireless connection icon doesn't even show up. Under device manager, my network adapter is listed as Realtek PCIe FE Family Controller. I've tried to download the driver from the Dell support site, but I'm not exactly sure which to download, and the few I have, haven't went well.There are 7 different things listed under other controllers, all with yellow question marks next to them. I'm not exactly computer savvy when it comes to things like this. Any help would be greatly appreciated!
