In all my wifi troubleshooting, I ran across a message that I’ve never seen before. As usual for a mac, it has very little information that would help a technical user. I found it interesting.
My guess is it has something to do with the "Michael algorithm" used in WPA…here’s a paragraph from Wikipedia:
"The Michael algorithm was the strongest that Wi-Fi Alliance designers could come up with that would still work with most older network cards. Due to inevitable weaknesses of Michael, TKIP will shut down the network for one minute if two frames are discovered that fail the Michael check after passing all other integrity checks that would have caught noisy frames. It will then require generation of new keys and reauthentication when the network restarts , forcing the attacker to start over."
Anyone else ever seen this?
