No Wifi After Clean Reinstall of Windows 10 Pro?

[paulyron]

I installed both of the files on the dell xps laptop.  There is no wifi still.  I don't even see the dell wireless drivers there.

After I type in my dell service tag on dell site... this is what shows as the drivers for MY PC.  Some show popular and some show popular and urgent.

I was able to get the wifi working by downloading those two network drivers.  Then opening and extracting the files.  I then clicked on check for windows updates and then it updated.  So now I have internet.  I then went to dell driver site and downloaded all the drivers that were labeled as urgent except the BIOS.  That is recommended right? 

 

 

The laptop appears to work but

 

But when I go to other devices, it shows these devices with yellow exclamation points.  These need to be fixed right?  Which drivers do I need to download for each of these?
