What is the size of ARP packets ?
When captured through a wireless interface, 68 bytes is typical for arp packets originating from wireless clients. 86 bytes is typical for arp requests from wired clients. On Ethernet, ARP packets when received are typically 60 bytes long. When this is then relayed by a wireless access point, they are 86 bytes. This is, of course, because of the wireless headers. If a wireless client sends an ARP, they are typically 42 bytes long and they become 68 when relayed by the AP.
