Indeed, I have noticed that we are are to react to any changes on the link quality. Your idea may helps a lot. Thank you. Do you know if I can safely rely on IEEE80211_TX_CTL_RATE_CTRL_PROBE and IEEE80211_TX_CTL_USE_MINRATE to detect probing and fixed-rate packets? I currently work on others parts, but I think I will try your suggestion in January. One last thing, do you know why minstrel appends the lowest rate and minstrel_ht don't? They should be identical, not? -- Jérôme Pouiller
