Dell XPS 15 9550 - No Wifi After Clean Reinstall Windows 10 Pro
I used my usb stick with windows 10 to do a clean reinstall of my maybe compromised dell xps laptop. So wanted to wipe it clean. I did the clean reinstall of windows 10 pro.
But when the screen turned on, there is no wifi connection. When you click on the bottom right corner, you see that globe which means you aren't connected to the internet. When you click on it normally, you see a bunch of wifi connections for you to connect to. Instead it shows
Network and internet settings
Airplane mode that is blank and you cannot click on it.
I went to troubleshoot and show available networks and it shows nothing.
This is what I see under device manager for network adapters and other devices
Network adapters
WAN Miniport (IKEv2)
WAN Miniport (IP)
WAN Miniport IPv6
WAN Miniport L2TP
WAN Miniport Network Monitor
WAN Miniport PPOE
WAN Miniport PPTP
WAN Miniport SSTP
These above appear to be installed? There is no yellow exclamation point or anything like that above. When I right click each one of these WAN, it shows device status this device is working properly for each one of these.
However the devices below do have yellow exclamation points and they show The drivers for this device are not installed (code 28) There are no compatible drivers for this device. To find a driver for this device, click update driver. Of course update driver does not work due to no internet.

bcm2045a0
Network Controller

Can anyone explain why I have no wifi and apparently no wifi adapter driver if that maybe the case? Note, my BIOS was very old before I did this clean reinstall. I remember it was like over 5+ years old at least and I never did a bios update. I never did an update because the concern of it bricking... made me never do a bios update. Could that be a reason?
I read that I should go to dell site and install all the drivers. I have my service tag and enter it on dell site. I would do this on another computer since I have no wifi on the dell xps. But how do I know which driver to install? Do I only download the network drivers first? I see there are 7 of them but none of these appear to be the wifi card that I had installed? I heard I have to download the drivers to a usb and then install it on this xps laptop?
Would connecting a usb wifi adapter that I use on a desktop and plug it into it... maybe give it wifi connection?

You're missing (probably among others) the chipset drivers, which you can get and install from here:
https://www.dell.com/support/home/en-us/product-support/product/xps-15-9550-laptop/drivers
Then install the wireless driver.

Hi. Can you tell me specifically which drivers is that? So first type in my service tag into dell site. Then it shows the drivers that are available. Do I click on network and download those? Or do I download the ones already shown on the page?
You say install the wireless driver but which one or ones is that on the page?

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 had downloaded the Dell Wireless 1820A/1830 Wifi driver and Dell Wireless 1820A Bluetooth Driver on my windows desktop. Then transferred the files to a usb flash drive... but got message
Are you sure you want to copy this file without its properties? The file ........ has properties that can't be copied to the new location. I clicked yes. Then I connected this usb to my dell xps laptop and I believe I installed both drivers. But there is no wifi nor the dell wireless driver isn't even shown when i search for it on start menu.

@quickguide01 I will try to help you once here. The Network Controller that you see in Device Manager is your WiFi card without any drivers loaded. View its properties, go to Details, and change the dropdown selection to “Hardware Ids”. You will see PCI Ven and Dev codes on a line there. Each will be four characters. If you Google those, you should be able to find out the WiFi card vendor and model and therefore the correct driver to install. If you can’t figure that out, post the VEN and DEV codes here.
Once you get WiFi working, you can download and install Dell Update to get most or all remaining drivers.

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?

@quickguide01 Download and install Dell Update, which will handle the necessary BIOS, firmware, and driver installations/updates. Get the Windows Universal Application version: https://www.dell.com/support/kbdoc/en-us/000187189/dell-update-alienware-update
