aljosa, thank you for reporting this and helping make Ubuntu better. To clarify, do you actually have a usability issue with the WiFi?
** Tags added: latest-bios-cdcn30ww ** Description changed: - Lenovo Y700-17ISK (Intel Core i7-6700HQ/RAM 16GB/SSD 512GB/Nvidia GTX960M 4GB) - Operating system: Ubuntu 16.04 (xenial-desktop-amd64.iso 04-Mar-2016, kernel 4.4.0-10-generic, nvidia 361.28) - - After installing Xenial, I installed all available updates too, and then I examined detally dmesg output in order to see if everything is ok between Ubuntu and my new notebook. - One month ago, wifi didn't work - but now this issue seems solved, at least partially... - - Current dmesg output: - [ 1.869368] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-8000C-19.ucode failed with error -2 [ 1.869382] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-8000C-18.ucode failed with error -2 [ 1.869392] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-8000C-17.ucode failed with error -2 [ 1.869589] iwlwifi 0000:08:00.0: Unsupported splx structure - - - I'm not an expert so I'm not sure about all (potential) consequences of this firmware problem, but I know for certain that this problematic lines shouldn't exist inside my dmesg output. - - When compared to other two Asus notebooks (both with Xenial installed on - ssd), my new Lenovo boots up much slower due to some other issues too: - - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1547934 - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1553685 -
