Qualcomm Atheros Wi-Fi Network Card Driver Issue Solved/Closed

Question

Hello,I have an Acer Aspire 5720ZG laptop that was working fine under Windows Vista. It is equipped with a Qualcomm Atheros AR5007EG wifi network card that operates through a utility under Windows Vista: Acer Enet Manager. However, this software is usually not necessary for the proper functioning of a wifi network card under Windows 8.1. Since I started using Windows 8.1, the wifi behaves erratically: sometimes it works... and sometimes it doesn't, so I have to uninstall the card driver each time via the Windows Device Manager and re-enter the password for my wifi connection for it to work more or less well. I tried installing a driver provided by the card manufacturer, but when the driver installs, I get a BSOD that says: IRQL NOT LESS OR EQUAL.How can I install a valid driver that doesn't crash my PC?Thank you in advance for your responses!Configuration: Windows / Chrome 36.0.1985.125

I'm getting another BSOD: IRQL NOT LESS OR EQUAL ... Otherwise, the problem isn't the activation of the card but rather the connection to a network that's buggy ..

Go to Windows Update and perform all updates.
Also check the optional ones and the hardware.
You may be offered a driver for the wireless.

I did what you told me but the same problem persists: the card activates but it struggles to connect and eventually disconnects...
Otherwise, Windows Update isn't offering me any updates for the Wi-Fi card...

I also tried to remove the security code from the box but to no avail....

Maybe check if the wireless configuration service is running and set to automatic in startup type?  If everything is correct, reset the modem.  Humans are at their best when things are at their worst.

The Wi-Fi seems to be working again, I disabled MAC filtering on my Livebox and for now I have no more problems...
