The issue in a nutshell is ...

1) 802.11b and older 802.11g (22 mbs version) are the two WiFi implementations that are vulnerable.

2) 802.11a (54 & 108 mbs) + 802.11g (54 to 108 mbs) are not apparently vulnerable.

3) The DoS exploit attacks the inbuilt Collision Detection technology in 802.11b.

We are going to ask our suppliers what they plan to do in regard to the threat & the technology they sell us (Warehouse Voice picking & Store front WiFi units). Doing this allows us to show the auditors we are aware of the threat and are taking 'action' :-)

*************************************************************

If we look at the timing of the news & the way it is worded, it can come across as a way to encourage sales of new 802.11g equipment & the squashing (through fear) of the 802.11b market.
