Check the output of iw list. You'll see something like this: Capabilities: 0x11ef RX LDPC HT20/HT40 SM Power Save disabled RX HT20 SGI RX HT40 SGI TX STBC RX STBC 1-stream Max AMSDU length: 3839 bytes DSSS/CCK HT40 If you don't see "HT Delayed Block Ack", then no. Also, your max AMSDU size may exceed what the driver/hardware is capable of. -Brian _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
