Very Old question but since I'm looking for the same answer I can add a bit of detail the other answers missed.
Wifi uses 3 address packets. Client MAC, AP MAC and destination MAC. An ethernet to Wi-Fi bridge has a problem because the ap will reject packets that don't have the client MAC address.
There's no easy solution that works with this design so wifi ...

Referring to the 4 states an 802.11 station can be with respect to the Robust Security Network (RSN), we see that:
moving from state 1 to state 2 happens when 802.11 Authentication completes successfully (the Open Systems Authentication you see in the diagram in the question)
moving from state 2 to state 3 happens when Association completes successfully

The 4-way handshake occurs after the client is Authenticated and Associated.
The 4-way handshake is used to generate the keys used to encrypt various types of traffic (Unicast, Multicast, Broadcast) between the AP and client.

40 MHz channels were only introduced in 802.11n (WiFi 4 in the new naming scheme from the WiFi Alliance). 802.11g (WiFi 3) and earlier physical layers, could not use 40 MHz channels. 802.11n, however, operates at both 2.4 GHz and 5 GHz bands. So if your clients support 40 MHz bands (802.11n, 802.11ac, 802.11ax - or WiFi 4, 5, 6, respectively), they should be ...
