WiFi not working in Lenovo Yoga 2 11" [SOLVED]

Post by piopio1949 »

Hello,

I have just installed Linux Mint 17.1 Cinnamon in my laptop and it's not working. Some people had been having issues with a bug in a kernel module which caused the OS to flag the device as hard blocked, but I have installed kernel version 3.18.1 and this is not the case anymore; running "rfkill list all" returns the following:

Code: Select all

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
However, WiFi still doesn't work. Even installing the vendor drivers from the Driver Manager didn't change a thing. Here's the output from mintWifi.py:

Code: Select all

By the way, the usb0 device is my phone; I'm just using it as a router in the meantime. ;) Here's the output from inxi -N as well, in case it could be useful:

I guess you guys/gals hear this a lot, but still I can't think of anything much more original at these hours: any help would be much appreciated. :D

You updated to a kernel higher than 3.15 and that is the issue, now you need a different version of bcmwl-kernel-source to get your wifi working and you need to go http://packages.ubuntu.com/utopic/bcmwl-kernel-source and then select whether you need 64 bit or 32 bit and select a download site and then install as this version was patched to work with 3.15+ kernels


Or you could uninstall the new kernel using Mint Update Manager, click View and then Linux Kernels and click on the 3.18 kernel and uninstall it. Reboot into the old kernel and

Code: Select all

sudo modprobe -r ideapad_laptop

Code: Select all

sudo rfkill unblock all
and there is a chance if you installed the latest 3.13.0-?? kernel using Mint Update Manager/View/Linux kernels that your wifi won't be hard blocked but even if it is blacklisting ideapad_laptop by

Code: Select all

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad_laptop.conf
might result in working wifi after a reboot

Re: WiFi not working in Lenovo Yoga 2 11"

Post by piopio1949 »

Hello,

While the first solution did not work for me, removing all kernels but 3.13.0, blacklisting the ideapad_laptop module and (re)installing the bcmwl-kernel-source module got this to work for me. I had originally followed all of your steps with kernel 3.13.0, but it didn't seem to work, which is why I installed newer kernels. However, the problem is that I had simply missed installing the appropriate driver.

Thanks a lot for your help, and merry Christmas! :D

Re: WiFi not working in Lenovo Yoga 2 11" [SOLVED]

Post by Alex.NET »

I'm still trying to install linux mint 17.1 x64 on my Lenovo Yoga 2 11" with no success.

Every time I boot from my usb stick I get into the grub menu select the first option and then ... black screen and nothing happens... :(

What I already did...

Disabled Secure Boot
Disabled FastBoot
Added r128.modeset=0, nomodeset, acpi_backlight=vendor, grub_gfxmode=1024x768x16 (in various ways)

maybe someone else has any idea

thanks in advance

Alex
