Windows 10: No WiFi appeared at all after updating to Windows 10 from desktop PC

I have a PC desktop computer and I thought it was time to upgrade from Win 8 to Win 10

However, after I upgraded it, I notice there is NO wifi icon at all (where I can type the username and password) and I even searched in the Network And Internet section area...

In contrast, I also have the exact same Win 10 computer in my other room and its showing the Wifi icon and its connected with no problem. (To be specific I am using the Apple computer but I use it as in Win10 bootcamp)

Obviously my PC has something wrong to it

I checked in the System and there is this yellow exclaimation mark under for
"pci simple communications controller driver"
and
"unknown devices"

For my Network Adaptor, according to what I see in Device Manager, it is "Realtek PCIe GEB Family Controller"

I even tried to uninstall and restart the computer and they still the same.

So I am not sure if they related to the problem and I can't update them either since I don't have the internet

I mean the main problem is in the Network Connection, I can see there is the icon for Ethenet but NOT Wifi at all like in the video below i.e.

Can you please how to solve it? Been trying to figure it out for days...

Thank you in advance!

WiFi disappears (802.11n Wireless LAN Card doesn't appear)

I have a PC with WiFi in my house, everything works with it, I have a good connection, but sometimes the Wi-Fi option disappears.

This is the problem:

The "PC Offline" icon appears on my desktop (A PC icon with a red X)

Then, when I touch that icon to try to activate WiFi, only the option of Airplane Mode appears, WiFi or Mobile Hotspot does not appear.

Then, I go to "Network and Sharing Center> Change adapter settings" and it does not appear either, only Ethernet appears.

The last thing I do is go to "Device Manager> Network Adapters" and 802.11n Wireless LAN Card does not appear

1-I have my drivers updated

2-It's not my antivirus or firewall

3-I downloaded all the drivers from the official page of my PC and installed, used and updated

PC info:

ASUS x450cc Windows 10.

 

Black screen after sign-in to user account before the desktop on Windows 10

At first I couldn't update from 8.1 to 10 online so I downloaded the update to a USB and installed it from there, now when I restart my PC I have to wait 10 - 15 mins for my desktop to appear after I have signed in. I checked all drivers and they were all
installed correctly and updated but I still have this LONG lag before I can do anything on my PC. Please can anyone help?

Hi, if Windows has not installed a driver, this tends to suggest maybe there isn't a compatible driver available.

Have you checked if your manufacturer has approved your desktop for upgrade to Win 10? Most manufacturers have published such a list.

Are you using a USB device or something else for WiFi for your desktop?
What is shown in Device Manager, Network adapters?
Realtek PCIe GEB Family Controller - appears to be for ethernet.

First see if there is a relevant driver on your manufacturer's site. Download and install it if so. You may have to use a driver for Win 8 for example.

At a pinch, you could try e.g. DriverMax (free) and scan for drivers. You may be in luck.

Please complete your system specs.
