Disable ACKs/Retransmissions #83

Open Seitam opened 8 years ago

Seitam commented 8 years ago

For study purposes I would like to know if it is possible to disable the ACKs and retransmissions by modifying the ath9k_htc driver/firmware. Some academic publications explain how they did it in the past by means of the MadWifi driver. Nowadays, with the MadWifi project deprecated I don't know if it is is possible to do it with the current replacement drivers (I am specially interested with the ath9k_htc for the usb support). After an intensive research on the web I haven't found any evidences that this is doable.

Any help would be greatly appreciated.

Hi, you could be interested in changing the HAL_TXDESC_NOACK flag on the transmitter side.

Hey @danzipie and @Seitam ,

Could you give me more info on how to enable the HAL_TXDESC_NOACK flag, please? I'm a newbie on this and I'm not sure how to do that.

I've seen that the HAL_TXDESC_NOACK starts with the value 2 by default.

File: open-ath9k-htc-firmware/target_firmware/wlan/ah_desc.h

define HAL_TXDESC_NOACK 0x0002

To enable it, should I change it to another value?

Cheers, Rodrigo
