Meu laptop vê um aumento repentino na perda de pacotes e na latência (de 0,0%, 1ms a 70%, 2000ms).
Permanece mesmo depois de retomar da suspensão para ram.
Permanece depois de:
sudo killall wpa_supplicant
sudo modprobe -r ath9k ath9k_common mac80211 ath9k_hw ath cfg80211 ath3k
sleep 1
parallel -j1 sudo modprobe ::: ath9k ath9k_common mac80211 ath9k_hw ath cfg80211 ath3k
Ele desaparece após a reinicialização.
