I've just installed Ubuntu 15.10 on my new Lenovo Yoga 700 (model 80QD). I got it working from command line, and i'm currently using my WiFi to write this, however, the Connection Manager does not let me configure the WiFi through the UI.

First issue: the firmware files /lib/firmware/iwlwifi-7265D-14.ucode and /lib/firmware/iwlwifi-7265D-15.ucode were missing (driver error message on dmesg). I downloaded them from https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware , as i could not find an ubuntu package with these two files.

Second issue: network manager refuses to manage this wifi device. This first symptom looked like the WiFi "switch" widget on the network menu on the top right of the unity window manager was off. Trying to switch it on, caused it to animated back and forth. Currently, after all my games, the wifi looks greyed out.

I've run the WiFi info script, attached below. Its clear that the rfkill command sees a "Hardware Block". Now first: i don't have a hardware rf kill switch on this laptop (User manual: https://download.lenovo.com/consumer/mobiles_pub/yoga_700-14isk_ug_en_201509.pdf ). Second, i'm currently using the wifi, just configured from command line. This can also be seen below, as the wifi is associated successfully (i used wpa_supplicant). And third, it also claims the bluetooth is hardware blocked, but i'm also using my bluetooth earphones while writing this, and i've configured them using the Ubuntu UI, which worked great.

I've also noticed:

GENERAL.STATE:                          20 (unavailable)
GENERAL.REASON:                         2 (Device is now managed)

below on the network manager info for this device, but i'm less familiar with what this actually means.

Thank you, would love except fixing this issue for the long term, if you could conjure a short term hack. Otherwise i'll have to keep configuring WiFi from the command line, which is quite annoying.

Edit 2: As requested, here is the steps i performed to connect to my home wireless:

sudo ifconfig wlp1s0 up
wpa_passphrase shlompiya <password> > /tmp/conf
sudo wpa_supplicant -Dwext -iwlp1s0 -c/tmp/conf
sudo dhclient wlp1s0
sudo sh -c 'echo nameserver 8.8.8.8 > /etc/resolv.conf'

Regarding to airplane mode: i forgot to mention i played with it, apologies. Airplane mode changed the software blocked settings when invoking rfkill list

I've managed to ugly hack it: i've recompiled the network-manager package, and made it ignore the "hardware blocked" rfkill mode completely. After this hack, i now have the UI working (but most likely i broke the software rf kill switch functionality). This will work for me for now, lets try to fix this for the next guy ;-)

recompilation and patch went something like this:

sudo apt-get build-dep network-manager
mkdir ~/laptop
cd ~/latop
apt-get source network-manager
cd network-manager-1.0.4
vim src/nm-rfkill-manager.c
line 168:
      return RFKILL_HARD_BLOCKED;
replace
//      return RFKILL_HARD_BLOCKED;
// PASH PATCH
nm_log_warn (LOGD_RFKILL, "PASH PATCH: overrided hardware killswitch state to not killed");
return RFKILL_UNBLOCKED;

End of edit 2

also, attaching systemctl status network-manager -n 1000 -l . If i understand the logging messages correctly, it indeed detects the hardware rf kill, and you can also see the switch to "unavailable" mode, which i don't understand what the reason 'managed' means. Edit: this had to be shortened due to character limitation on question length.

  • Please edit your question to include to process to start the wireless from the command line. Also, you laptop does have a kill switch. It is called 'Airplane Mode.' Airplane Mode:on is the same as Wireless Radio:off. As you manipulate the Airplane Mode switch, is there any change in: rfkill list all?

  • done. like i edited, the airplane button only changed the software blocked in rfkill, and apologies for forgetting to mention it. Also, i've hacked myself a solution: i've recompiled network-manager to ignore hardware rfkill switch completly, and now my WiFi UI is working well (hack detailed in edit). So personally i'm set, but i will help with what i can to fix this correctly for the next guy.

  • digging a bit more in sysfs, i found cat /sys/class/rfkill/rfkill0/name says ideapad_wlan . From the network manager source code, it seems that it has "slots" for rf kill switches, and this one registers into the "WiFi" slot, completely disabling wifi (so it's not the iwlwifi drivers fault at all). searching for this driver on google turns out this is the most common issue with it, and some suggest blacklisting it (though it contains more functionality). I therefore think maybe i should contact the driver maintainer? What do you think?

Future seekers of help:

The fault seems to be with a buggy ideapad_laptop driver, which is not a unique issue to this laptop / model.

in order to get around issue #2, one possible solution is to just blacklist the driver, as suggested here: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Wifi-is-hardware-disabled/td-p/1307405

Don't forget to solve #1 you'll need to download the new firmware: https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware

For future reference: here is a link to the bug on a different model on lunchpad, i've added a comment about this specific model so it can be added to the driver. If this reproduces on OTHER MODELS, run dmidecode and check if you machine model is in the list inside the driver drivers/platform/x86/ideapad_laptop.c (https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1397021)
