Claim:
1. A method of transmitting an Internet Protocol (IP) packet using an 802. 11 link to a destination device, comprising: receiving the IP packet over an air interface, the IP packet comprising a Media Access Control (MAC) header, an IP header, and a data packet payload, wherein the data packet payload including a unit ID packet having information uniquely identifying the destination device for the IP packet and Forward Error Correction (FEC) packet to perform FEC on the unit ID packet; detecting an error in the IP packet; forwarding the IP packet to a packet evaluation layer in response to said detecting; determining, with the packet evaluation layer, that the error precludes obtaining a destination address for the destination device from the IP header and the MAC header; obtaining the destination address based on the unit ID packet included in the data packet payload in response to said determining; forwarding the IP packet to the destination device based on the destination address obtained via the unit ID packet included in the data packet payload; and performing forward error correction on the unit ID packet with the FEC packet to ensure that bits contained in the unit ID packet are unlikely to suffer a transmission error.
