A method and a system are provided to determine and thus select the best choice for antenna to be used by a network device having a plurality of directional antennas for a particular sending source. The determination is made using on a metric based on the success rate of packets received at a particular directional antenna from the sending source and secondarily on a received signal strength indicator. The determination is stored and made available for processing such that a router is able to request communication through a device with a destination via the second wireless communication device without knowledge of the best antenna match. In a specific method the first communication device broadcasts packets, via each associated directional antenna, to query for the existence of the second wireless communication devices. The first device then receives a plurality of information packets about existence of the second wireless communication devices in response to the broadcast packets or in response to a query about third parties. As between each directional antenna and each second wireless communication device, a packet success metric is determined for each directional antenna, which becomes the basis for antenna selection.
