It's intensely paranoid to switch the wireless off. It's quite unlikely that someone with the necessary software and time is sitting outside your home right now trying to decrypt your WiFi traffic.

Last I heard patches will be across the board. Clients can also be patched. If either of them are patched the attacks no longer work.
Either way as the article says if you've some shady hoodie outside your home tapping away on a laptop you likely have bigger things to be concerned by than your wireless traffic being eavesdropped on.
