Description of problem:
On a laptop DELL Precision M4800 with Dell wireless 1550 which corresponds to Broadcom BCM4352 [14e4:43b1) (rev 03)

Just after login activation of wireless link seems ok (see /var/log/message at 16:49:00) but the link fails after some time (/var/log/message at 16:49:53) and attempts to reconnect always fail (/var/log/message at 16:50:08)

Additional info: I have desactivated IPV6 in /etc/sysctl.conf. Does not change the behavior but I don't understand why there are still somme messages about IPV6 in /var/log/messages......
