I too have a Lenovo Yoga Pro 2 running Ubuntu 14.04, and I too need to rmmod/blacklist the ideapad_laptop module to get the wifi running.
Experience the exact same behavior while testing with the following kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic /linux- image-3.15.0-031500rc5-generic_3.15.0-031500rc5.201405091635_amd64.deb ** Tags removed: kernel-unable-to-test-upstream ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1318038 Title: 8086:08b2 [Lenovo Yoga Pro 2] WiFi does not work if 'ideapad_laptop' module is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1318038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
