After long time I am happy now, because I surprisingly found a workaround that fixed this issue for me, with neither opening the case nor using/installing any proprietary software like Windows, etc.
I booted with a KALI-Linux Live-CD to try to recover some lost pictures from an IPhone that got deactivated because the children entered a wrong passcode too often... Then KALI-Linux told me that the Airplane mode is on and I should use the hardware switch to turn it on. Thus I turned it off and on again, the same procedure which was useless for so long time with ubuntu. When I turned the switch on again, there was some disc activity and suddenly Wireless LAN started working again and I could connect to WLAN. After some unsuccessful tries with the IPhone :-( I was leaving KALI- Linux and booting from hard disk again, and found: Wireless LAN is still working! :-) Then I stored the nvram and compared with and old nvram image: They both have the same size and MD5sum. Thus the information if the hardware switch is on or off seems to be stored somewhere else, but not in the area used for nvram. Probably the flash memory available is bigger than the area used for nvram and the information is stored somewhere else. As KALI Linux is Open-Source, it is very likely that it is possible to find a solution for Ubuntu and to try out what turns Wireless on or off. Here is a small HOWTO howto fix the issue: (I wrote it very detailled, so that almost everybody that finds this here can use it) - Download Kali Linux: https://www.kali.org/ and download directory is http://cdimage.kali.org/kali-2016.1/ wget http://cdimage.kali.org/kali-2016.1/kali-linux-2016.1-amd64.iso wget http://cdimage.kali.org/kali-2016.1/SHA1SUMS wget http://cdimage.kali.org/kali-2016.1/SHA1SUMS.gpg - Check that your download is not corrupt and is authentic gpg --verify SHA1SUMS.gpg SHA1SUMS The output should be as follows: gpg: Unterschrift vom Mi 20 Jan 2016 21:37:00 CET mittels RSA-Schlüssel ID 7D8D0BF6 gpg: Korrekte Unterschrift von »Kali Linux Repository <de...@kali.org>« gpg: WARNUNG: Dieser Schlüssel trägt keine vertrauenswürdige Signatur! gpg: Es gibt keinen Hinweis, daß die Signatur wirklich dem vorgeblichen Besitzer gehört. Haupt-Fingerabdruck = 44C6 513A 8E4F B3D3 0875 F758 ED44 4FF0 7D8D 0BF6 Now you know that the SHA1SUMS file has been signed with the key, but you still cannot trust the key. Compare the fingerprint with the one listed on https://www.kali.org/downloads/ and check the https// certificate. If you trust the https// certificate an the finger print there equals the one from gpg --verify, then you can trust the key used for the signature and the signed file. Now you need to check the file against the trusted SHA1SUM sha1sum -c SHA1SUMS The output should be as follows: kali-linux-2016.1-amd64.iso: OK ... If you didn't download all the other files mentioned in the SHA1SUM file, SHA1SUM will complain about the other files, but that can be igored. The SHA1SUM of the file should be: deaa41c5c8f26b7854cafb34b6f1b567871c4875 kali-linux-2016.1-amd64.iso Now you can be quite sure that you got an authentic copy of KALI-Linux and can write it onto a DVD: growisofs --dvd-compat -Z /dev/dvd=kali-linux-2016.1-amd64.iso Then boot your Lenovo ideapad from this CD (you need an external DVD drive for it). In the network settings dialog try to enable WLAN. If it does not get detected immediately, turn the Wireless Switch off and after some seconds on again. Now the wireless LED should be on and Wireless should work. You can then shutdown KALI Linux and boot into the installed system and Wireless should still work as it should. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/577114 Title: [Lenovo IdeaPad S10-3] Wireless and Bluetooth switch does not work correctly on lenovo ideapad s10-3 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/577114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
