Yes I thought about wlan0 not being available, and I purposely rebooted the laptop making sure that the network kill switch was on etc... wlan0 came up right away, but net.ipv6.conf.wlan0.use_tempaddr was equal zero (the other ones were equal to one). I also check the spelling and copied and paste from a sysctl command line.
I know this works as advertised on my other laptops, but, the older ones are T60s and running Ubuntu 10.10 32 bit, the one with the problem is a new x220 running Ubuntu 11.04 64 bit. There is one of the T60 that could run 64 bit, I'll try to upgrade it as soon as I get a minute for comparison purpose. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803739 Title: value set in /etc/sysctl.conf not used at boot time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/procps/+bug/803739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
