[Solved] Lenovo qualcom atheros AR9565 wifi notworking

[aeromac]

I have a lenovo yoga 2 11 laptop with a qualcom atheros AR9565 network adapter and I have no WIFI on my Linux Mint 17.1 Cinnamon. Trying to research what need to be upgraded. is it the Kernel or a driver? My kernel is 3.13.0-37 and I know there are several updated kernels and which one might fix my problem or is it a driver upgrade I need?

Thanks for any help I can get.

Open a terminal window and enter

Code: Select all

rfkill list all

and paste the results

Done that, didn't fix it. Also the Bluetooth hardware shows hard block but it works you can turn on Bluetooth but the wifi won't turn on even when I built a wifi connection with security, DNS servers and such.

I personally had this problem and researched all day today. Tried lots of stuff but after inputing the codes :

Code: Select all

sudo apt-get update

and

Code: Select all

sudo apt-get dist-upgrade

it finally fixed the problem after rebooting. Hope it helps, good luck!

With the Yoga2 you can go into the Update Manager, click View and then Linux Kernels, then select the 3.16.0-30 kernel to install and your wifi should work again. Lenovo changed how they reported the hard block on these laptops and it caused linux users problems until the kernel developers found the problem and got the patches submitted

I thought about upgrading to 3.16, but from everything I have read it's best to stay within the 3.13 and only do point updates which i have. I might just try it and see what happens.

What I have found out is there is two wlan0's in the rfkill list all. there is two wlan0 listed one pci and the other ideapad and it's the ideapad which is listed first and the hardware blocked. I think i might have to black list this some how to remove it from the /etc/modprobe list. Has anyone seen this? Am I on the right track?

I wouldn't hesitate to use the 3.16.0-30 and it isn't difficult to remove a kernel by using grub menu at boot(press and hold shift key to make it appear) and select previous version then select the old kernel to boot from and use update manager to remove the newer kernel.
The alternative is usually

Code: Select all

sudo modprobe -r ideapad_laptop

Code: Select all

sudo rfkill unblock all

and see if it works

WHOAH the modprobe -r ideapad_laptop worked. I now have WIFI and i'm back on the kernel 3.13.0.45 version

Thank you.

You will either need to run the sudo modprobe command after boot/suspend or you can blacklist it

Code: Select all

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

Removing ideapad_laptop either by blacklist or modprobe -r may cause FN combos to fail

The code in the 3.16.0-30 changed how ideapad_laptop handles hard blocks for the Yoga models without hardware switches

oh your good. I was just getting ready to ask how to make it permanent. blacklist or add a command to rc.local.
