I've attached log of network-manager with debug enabled on both 11.10 and 12.04, notice the differences between both logs.
I don't know if it's related, but on ubuntu 12.04 the 'iw' command is broken and complains about missing nl80211. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/994739 Title: wireless takes several seconds longer to connect from standby To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/994739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
