Works for me on Z570 (iwlwifi), could you please provide relevant output from dmesg? ideapad platform code seems ok, judging by other reports, i'd say there is problem with ath9k rfkill unblock. Try this workaround for the moment: # rmmod ath9k && modprobe ath9k I will provide dmesg output soon. Anyway rmmod ath9k && modprobe ath9k does not help. The problem is that the command rfkill cannot unblock the wifi card (ath9k) from hardware lock. (The same result with Fn+F5). Maybe the problem is in the rfkill but I'm not sure.

Let me know if you need additional info. THX for you effort. All info is taken from SystemRescueCd but the results are the same with all other distros (Centos, Debian, Ubuntu) The bug: https://bugzilla.kernel.org/show_bug.cgi?id=42898 Is it the same? No.. 42898 is about an HP device Ok, sorry. I care about getting this fixed, so I'm offering USD 50,00 via FreedomSponsors to the first person who fix it. Offer link: http://www.freedomsponsors.org/core/issue/423/ideapad-laptop-driver-does-not-unblock-the-wireless-card-form-hard-block You can also join me and throw in a few bucks there and we'll get it fixed faster :) If you fix this issue (see my acceptance criteria there) please use that site to request your payment. I consider to close this bug because the combination fn+f5 on this Lenovo laptop model is related to Wireless and Bluetooth hardware switch and in Windows OS it pops up a graphical menu where you can choose Wireless or Bluetooth to enable or disable. I think that in Linux console fn+f5 will not have straight function and makes the things unclear. Maybe a separate key combination for Wireless and Bluetooth is needed as is in some other laptops. What do you think about this ? Hi. The wifi switch (in one side) is on. And I have been trying with your key combination (fn + f5) and the wifi is not run yet. $ rfkill list all 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: yes 1: ideapad_bluetooth: Bluetooth Soft blocked: no Hard blocked: yes 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes Bye. Yes you cannot unblock the wifi card on this and similar laptop models so you can not use wifi under Linux if it is blocked (of course you can unblock it on other OS and use it under Linux after). The problem is that fn+f5 is related to Bluetooth and Wireless so maybe the proper behavior is to disable/enable both Wireless and Bluetooth because you can't have graphical menu under linux console for example. This is just what I think. On kernel 3.15.7 (gentoo patches), if I rmmod ideapad-laptop, it works properly. The moment ideapad-laptop module is loaded, wifi/bt gets hardblocked. There's really something wrong with the module. How many of you are dual booting? This problem Windows hard blocking the device, as well as a BIOS bug on some devices. I will close this bug because cannot test it anymore (obsolete). But, What do you need? I can help you. |
