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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1318038 Title: 8086:08b2 [Lenovo Yoga Pro 2] WiFi does not work if 'ideapad_laptop' module is loaded Status in “linux” package in Ubuntu: Confirmed Bug description: After installing Ubuntu 14.04 on my shiny new Lenovo Yoga Pro 2, I didn't have any WiFi.
