Comment 5 for bug 803739

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.
