im trying to capture the EAPOL packet from my own network and i have succeed, in parts.

I have 2 wifi cards running on the same laptop:

  1. Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
  2. ZyDAS ZD1211B 802.11g (USB)

Im connected to the same AP (G only mode) and at the same channel. With the atheros card i hadnt any issue to capture the EAPOL, but with the ZyDAS i was not able, still i captured some (beacon/probes/ACK) packets.

Can anyone give me some hint on why this is happening?

thank you.
