As I mentioned in my previous post about Ubuntu, the wireless was working fine without any rfkill unblocks. But things changed when I did an online update using the Ubuntu update manager. After the update was completed and after the reboot, my wireless stopped working as it showed in the network manager that my wireless card is disabled. The option to enable wireless was faded out and the external button to enable/disable wireless was not working.
For now, I did the workaround by adding "rfkill unblock all" to the /etc/rc.local file, before the exit 0 line. The workaround is working fine now. I do hope that by the time Ubuntu 11 comes out, this bug is resolved.
