I am trying to find out how arp works on 802.11 infrastructure mode.
When a station sends out an ARP broadcast do other stations get the broadcast and send out a point-to-point response that the origination station receives? I thought all a stations traffic when directly to the AP but this doesn't fit with ARP.
In infrastructure mode the AP relays all traffic from one client to the other. There is no direct traffic between thwo clients.
The ARP request (to the broadcast MAC adress) will go to the AP, it will relay it to all WLAN clients and into the LAN. The ARP reply will go from the LAN or the client to the AP and from there to the requesting client.
