The problem resurrected after I was playing around with WWAN card, I guess it was due to enabling and disabling the card in the bios. I was again able to fix it by restoring my pre-installed Windows image, and then restoring my Ubuntu image.
@owang: I have like yourself tried all solutions I could find on the web, and nothing works. I have absolutely no idea how the Windows restore fixes the problem. (is Windows able to write some changes to the bios??) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/812866 Title: Wlan hardware blocked after suspend lenovo X121e To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/812866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
