Wireless connectivity

[Scorpiusmaximus]

My wife bought an Acer laptop about 4 months ago, and has been having trouble with wireless connectivity ever since.
Her model is:Acer Aspire V3-551G, and wireless card is Atheros AR5BWB222 wireless network adapter.
We have checked out numerous avenues to get it working properly.
The problem is that it takes a looooong time to connect to our home network. It should be connecting relatively straight away, but can take up to 1/2hr to connect.
When i go to Network and Sharing Center, then Connect to a network, our network shows up, i try to connect, it fails, then network drops out.
No other laptop, or even the desktop has this problem.
I an thinking there is a problem with the wireless network card, and am wondering what would be a good replacement card?
Yes, we have tried all software routes that i can think of, updating drivers for starters, even done a complete re-install.
Any help appreciated guys/gals.
Cheers.

Download the latest Wireless LAN driver from here if you didn't try the latest; remove the old ones first using device manager and restart.

Thanks.

Well, for a minute there i thought it was ok. uninstalled, then re-installed drivers, connected almost straight away. Restarted, took about 2 mins to connect, then about a minute later wifi dropped out.
Like i said previously, this isn't happening with any other laptop/desktop on our home network.
Help guys, the missus is getting really annoyed with this, and me :lol: :lol:
Cheers.

also check your router for the newest firmware. sometime there are issue with diffrent wifi chipsets.
