My laptop is Lenovo Yoga 910. I have Ubuntu installed however I cannot connect it to wireless network. Wifi just cannot be enabled. Also since this is an ultrabook it does not use ethernet. I am using dual OS and wifi is on and works fine on Windows 10. Is there any driver I should install? I am completely new to this, please be specific. Thank you.

    Open terminal (CTRL + T) and enter lspci -nnk | grep -iA2 net Does this show a wireless interface and something next to kernel driver in use? Also check rfkill list all Does it show something blocked?

It seems that a kernel module is blocking wifi, so

echo "blacklist ideapad-laptop" | sudo tee /etc/modprobe.d/ideapad-laptop.conf
Reboot and see if the hard blocks are gone

I would suggest filing a bug report at bugs.launchpad.net/ubuntu against package linux and then follow instructions

  • This worked for me back can you explain in your answer what it does?

    The command keeps the ideapad-laptop module from loading. A year or so ago a change was made to the rfkill registers in BIOS of some Lenovo laptops/netbooks that falsely reported wifi as blocked with the ideapad-laptop module. You could file a bug report against linux as your issue may have been fixed with this commit in the upstream kernel development
