Wireless?

I have an Acer Extensa 4420, (AMD Athlon(tm) 64 X2 Dual-Core Processor tk-57 1.90 GHz 3.00 GB RAM, 32-bit Operating System, Windows Vista Home Premium) and I cannot connect to the internet through wireless. There's a switch on the bottom, and I flick it, and it says WLAN Enabled/Disabled. But otherwise it's like the card isn't even there. It doesn't pick up the wireless network in my house when all the other computers do.

I bought it from the retailer last year, and the wireless has never worked.

I downloaded the drivers from the Acer website and when they try to install they say the card isn't in the computer.

I can't find any other problems like this through other questions answered. I tried trouble shooting it myself but I cannot try anything else.

It's driving me mad, please help.

 

If it is still under warranty, contact your retailer...

 

Does the device manager show any wireless cards and if so are the drivers properly installed or is there some kind of a problem with it (indicated by an exclamation mark)

If the card is indeed there and installed properly you may want to open the hatch that covers it at the bottom of the laptop and check if antennas are connected. If the device manager shows no wireless cards present you may want to do the same to verify that there's one there at all.

 

I poked around some more, opened the bottom and got this number off of the card.

Broadcom
BCM94312MCG
FCC ID - QDS - BRCM1028
4324 - BRCM1028

I plugged that into Google and tried the drivers, but I think I'm doing something wrong.

EDIT :

I fixed it.

I downloaded this and then updated the driver by right clicking, update driver, selected the unzipped file and boom.

Thanks for your help~

I was frustrated because I only seemed to find help for installing it on a Windows XP OS. But- it was really simple.
