ok, didnt work with the ipv6 disabled in nm-manager, here is the dmesg. as you can see I am also subject to a bug that seems to be related to 802.11n poorly supported. However I disabled 802.11n following a google research :
cat /etc/modprobe.d/iwlagn.conf options iwlagn 11n_disable=1 But, that's another bug. As is the fact that Xorg was eating 40% CPU time. That nautilus was completely irresponsive, amarok could not stop, the unity launcher had a bad behaviour and the reboot command from the user panel was not working the first time (asked what to do with amaraok then … nothing). Sorry, but I think I have to complain. there is something fishy in the network-related resources. it seems activities (Xorg ?) are spinning on devices, and that nautilus should be implemented with Inversion of Control and double buffering for the model. because here, when the newtork starts hanging, the nautilus window just hangs and doe not respond to anything, even the redraw() from the OS (having a white window) back to this ubg, I am modifying GRUB to disable IPV6 at startup. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1096853/+attachment/3573534/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1096853 Title: 14e4:4353 Wi-Fi disconnects then cannot connect to any network -- Broadcom BCM43224 bcma To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1096853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
