[Click] 11n monitor mode NOT answer ACK

[Javier Sánchez]

I have no idea then.

Is the packet being transmited correctly from the source device (you can use
dump on 802.11n monitor device to verify) ?

What driver are u using? u can try to look at the code  (packet injection
code), may be ack flag is desactivated on packet injection ¿?

on madwifi, ack can be desactivated like this

    if (IEEE80211_IS_MULTICAST(wh->i_
addr1)) {
        flags |= HAL_TXDESC_NOACK;    /* no ack on broad/multicast */
        sc->sc_stats.ast_tx_noack++;
        try0 = 1;
    }

Regards
Javier
