Public bug reported:
Binary package hint: network-manager
Lenovo T60 with an Intel wireless card.
Wireless worked flawlessly in 9.04 and 9.10. My other computers still
running 9.10 don't have any problem on the same wireless routes.
Just upgraded to 10.4 beta and often runs into these two problems.
1) after resuming from suspend, it cannot connect. Looking at daemon.log
I see:
NetworkManager: <info> (wlan0): supplicant connection state: 4-way handshake
-> associated
aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping
packet
aristotle avahi-daemon[911]: Registering new address record for
fe80::21c:bfff:fe08:704a on wlan0.*.
aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping
packet
aristotle wpa_supplicant[1055]: WPA: Could not verify EAPOL-Key MIC - dropping
packet
2) sometimes it just disconnect. This seems to be related to traffic, it
only happens when streaming video from the net (youtube, vimeo, etc...).
Doing a tail -f on daemon.log, this appears at the exact time that I
loose my connection:
wpa_supplicant[1055]: CTRL-EVENT-DISCONNECTED - Disconnect event -
remove keys
