Trouble installing laptop wireless card drivers

I'm installing windows 7 Home Premium 64 bit on an Acer Aspire 5742z w/o the recovery partition or CD's, so the original drivers are gone, but I still do have Acer's Website. Every time I try to install the wireless card's drivers the computer hangs at approx. 70% into the installation. This happens both when I run the setup exe, and when I choose to browse to the driver manually. I've uninstalled the driver & went through this process multiple times. After rebooting, the driver appears installed in the device manager, but with errors. It's shown as "Broadcom 802.11n Network Adapter" with an exclamation point next to it.

Hardware ID: Ven_14E4 Dev_4357 &Subsys_E021105B &Rev_01

Driver I'm using:

http://global-download.acer.com/GDFiles/Driver/Wireless%20LAN/Wireless%20LAN_Broadcom_5.100.82.95_W7x86W7x64_A.zip?acerid=634545309485165023&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE%205742Z&OS=ALL&LC=en&BC=ACER&SC=EMEA_27

There are no other unknown or damaged drivers, even when hidden devices are revealed.

Looks like a known issue with acer aspire laptop.

Go to acer website and download the latest version of the bios update.After installing bios update... reboot and then try installing the wifi driver.

Updated the BIOS to the latest version. I was doubting that the wireless card was bad because I believe it worked before the re-installation, but I'm having the same issues, and am now looking into simply getting an external wireless wifi adapter and being done with it. If anyone has any other ideas, please let me know.

You can check wireless settings in bios. If the issue persist then follow nobus suggestion

if you follow my procedure - you can test the wireless card on another PC
another option is to test it when booted from a live Knoppix cd :
