The wired TCP is probably running over Ethernet, without IEEE 802.2. 802.11, however, always uses 802.2, so there will be a SNAP header. The fact that it's 0:0:f8:8:6, which means a SNAP OUI of 0000f8 and a protocol ID of 0806 (ARP), means it's some type of Cisco bridging (0000f8 is one of Cisco's OUIs). The "(0:2:2d:91:3a:82)" in the ARP reply probably means it's trying to print both the MAC address and the name in the ARP reply but it couldn't or didn't try to translate the address to a name.
