QUT Researchers Find WiFi Flaw

Researchers at the Queensland University of Technology have discovered an easily-exploited vulnerability which can be used to take down most 802.11 wireless networks. The flaw operates at lower network layers than most previously-discovered security flaws in 802.11 networking, and affect any network operating at the 2.4GHz frequency — which is the sole frequency used by the most popular wireless protocol, 802.11b
