An 11n capable AP, but connected to a 54G mode did NOT produce a _single_ DUP! packet! Well over 2000 packets transmitted, not a single one duplicate. This clearly isolates the problem to 54 B/G-Only APs. Regarding your request for a capture file where duplicate packets occur, I have this to ask. I found out rt2800usb has the ability to switch to monitor mode - while connected to the AP and the gateway is ping-able. Will a capture from the same PC connected to the AP do the job for analysis? It will take me some time to set up a second station running the rt2800usb module and capture communications between the AP and the said PC. Please let me know.
