WiFi driver issue

Hello,

Go to the device manager
Give the hardware ID number of the device
Right-click on the device
Properties
Details tab
Select the hardware ID number.
It's a number that should look like this for example:
--> PCI\VEN_1969&DEV_1026&SUBSYS.......
If needed, check --> here

What do you have in network adapters?

--> Operating system?
--> 32 or 64 bits?

First of all, thank you for responding so quickly and taking the time to help me solve this problem :)

Next, for what you asked me:

Hardware ID (There are 4 on the same hardware, so just in case, I'm listing them all xD):
- PCI\VEN_14E4&DEV_43B1&SUBSYS_85BA1043&REV_03
- PCI\VEN_14E4&DEV_43B1&SUBSYS_85BA1043
- PCI\VEN_14E4&DEV_43B1&CC_028000
- PCI\VEN_14E4&DEV_43B1&CC_0280

Network card: ASUS PCE-AC56 802.11ac Network Adapter #2

Operating system: Windows 7 (64-bit)

Note that for the PC I am currently using, everything is identical (except for the network card where one has the "" #2 "" while the other does not) and it works very well ^^ (just the motherboard is not the same)

Download and install --> 7Zip 64 bits

Download this driver --> Broadcom
and put it in your documents.

Right-click on --> Broadcom....zip
Choose --> 7Zip
Choose --> extract to Broadcom......

Go to the device manager
Right-click on the device in question
Update driver
Search for a driver on my computer
Browse
Go to your documents
Go to the unzipped driver folder --> Broadcom.....
Folder --> Driver
Select the folder --> win7
OK, next
Restart

After doing all that, still nothing.

I have to go through software to configure my wifi network (Asus PCE-AC56 WLAN Control Center), but when I launch it, it keeps telling me "Please connect the ASUS wireless adapter to your computer before running the utility."
But the PC recognizes the wifi card, yet I can't do anything as long as the software hasn't recognized that it is indeed installed.

Still nothing...
No alert message.
I still uninstalled the driver, restarted, reinstalled, restarted again, and still nothing. I'm at the same point :/

In the device manager
What do you have under network adapters?

Network card:
- Broadcom 802.11ac Network Adapter
- Hamachi Network Interface
- Intel(R) Ethernet Connection (2)I218-V

No, it was not activated.
So I switched it to manual to start it, restarted the PC but still nothing :/

Double-click on the wireless WLAN automatic configuration service
What is the status of the service?

He is currently stopped (even though I was sure I had started it xD)

Click on Start and set it to Automatic in Startup type
Apply and OK.

Done. A restart is required, I suppose? ^^

Good news, it finally recognizes the driver ^^
Bad news, it can't sync the connection ... The bandwidth isn't stable :/

Reset the modem and the router.

Still not working. Everything is identical on both PCs except that it won't connect :/

Maybe a problem with the modem?
Is the PC far from or close to the modem?
Is the network cable (Ethernet) properly unplugged?
Lots of devices connected via Wi-Fi?

The PC is very close to the modem for the moment (not even 2 meters away from it). Ethernet cable is well unplugged.
We had 6 devices on the Wi-Fi (which works perfectly) and after removing 2, the problem persists.
At first, I thought it was because of Chrome since as soon as I launched it, the connection would drop, but no, even when doing nothing, it still drops :/
It's just the PC that doesn't want to maintain the connection, but I can't figure out why T-T

Go to Start
In the search bar
Type --> services.msc and OK.

Double-click on the Wireless Auto Configuration WLAN service
Set it to manual in the startup type.
Apply and OK.
Restart the PC.
Might not be related, but worth a try.

What is the antivirus?
Have you tried disabling the antivirus?

Sorry for the delayed response. My box had the brilliant idea of burning out due to a storm :/

So, for what you asked me to do, it turned out the same as before. Basically, the PC doesn't recognize the driver. I put everything back the way it was, and now I have the same connection problem that won't stabilize.

As for antivirus, I'm using Microsoft Security Essentials. I tried disabling it and it's still the same.
