This
wpa_supplicant[4035]: WPA: Group rekeying completed with
00:0f:a3:1c:a0:8b [GTK=TKIP]
seems to be what causes DHCP renewal (every 30 seconds!!) subsequently
to fail.
** Summary changed:
- wireless disconnects due to failed lease renewal
+ Wi-Fi disconnects after failed DHCP lease renewal due to TKIP rekeying
** Changed in: network-manager (Ubuntu)
Status: New => Incomplete

Title:
Wi-Fi disconnects after failed DHCP lease renewal due to TKIP rekeying
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Wireless disconnects randomly (about every 10 - 30 minutes) and won't
reconnect automatically. By looking at syslog, it looks like this is
because network manager marks the connection invalid. The cause of
the disconnects seems to be the lease failing to be renewed. This
problem only happens when I'm connected to this particular wireless
switch (called default in the log), but doesn't occur to others using
windows and mac os. The wireless driver I use is wl.
