It's a common concern that wireless access points broadcast their signal into areas that would allow hackers to bypass certain physical security measures that are in place, through use of sniffer or other WEP cracking tools. If an access point is protected with a strong WPA2 key what difference does it make whether the wireless signal is broadcasting into areas where hackers have access ? Using a strong WPA2 key would render the wireless network authentication being used virtually uncrackable.

I would think that this concern would only apply to businesses that are ignorant of wireless security, or are not financially stable enough to upgrade to hardware that supports WPA2.

Yes WPA2 is a lot harder to crack. But WPS is much easier and most routers have that feature enable unknowingly.

It actually depends on the key space used in WPA2, whether it will be crackable. WPA2 supports a large "key space", and when a very large password is used to take advantage of WPA2 technology, say the maximum 63 characters, it would be virtually impossible to crack. It would take too long with current technology.

But say you used only a 15 character password under WPA2... You wouldn't be taking advantage of the key space supported under WPA2 so it would be as crackable as any other relatively short password.

Total agree with your WPA2 comments.
But as I said WPS is enabled on most routers and the pin is only 8 numbers( it's the pin usually written on the underside of the router ) and it is now able to be crack even if you have WEP, WPA, WPA2 encryption on your network. It's a brute force attack on the pin. Were as WPA2 is a dictionary attack.
Reaver was release at the end of last year to crack WPS. So unless your router manufacture has released a firmware update to fix the WPS venerability and the router has been flashed then it's still venerable to the attack.
You can run Walsh to chech if your router is venerable to a reaver attack.

That's scary. I just read more about it on Wikipedia.
