I'm having a problem with wireless connectivity in an Acer notebook?

I'm at my wit's end. I'm about to pay money to have this thing fixed. I have an Acer 5050-3785 Aspire notebook. I changed the operating system from Vista to XP Pro. Ever since, the wireless WLAN card hasn't worked. I've downloded every driver from here to Timbuktoo. No love. It's odd because the LAN card is a Realtek but the WLAN card is an Atheros. I can't even find the model number of the Atheros WLAN card. I've tried to set up wireless networks about 10 billion times. Nothing. What in the world am I doing wrong?

I forgot to mention that it's a Atheros 802.11 b/g wireless card. That's about all I know about it.

Assuming you bought the laptop in the USA, you should be able to find the one and only good driver on http://us.acer.com/ac/en/US/content/home, select support, drivers for notebook, aspire, 5050 and select the proper operating system (xp pro) down on the list you will find the driver for Wireless Lan Atheros. version is 5.1.1.9 dated 2008/12/03.

Go Control Panel, Administrative tools, computer management, device manager, network adapters. Select your Atheros card, right click and select properties, tab driver. Uninstall driver and install the driver you just downloaded from acer.

If that doesn't work download the software on the acer's site "need to know the hardware ...." on the download page.
