If you have a wireless network using WPA, read this. A PhD candidate recently discovered a way to compromise a wireless network using WPA. Fortunately, the attack only works against TKIP (the default from what I’ve seen). The fix is to switch to AES encryption, usually the second option when you’re configuring WPA. I had already selected AES just to be different. In this case it worked out nicely.
