Need help with Atheros AR9285 Wireless Network Adapter

Question

Guys I couldn't get my wifi working. I've worked for long using just lan. But, tomorrow, I urgently need working wifi. Help :))

Thing I've tried:

Checked bios - wifi enabled
Tried clicking fn + wifi button several times

My output for lspci | grep Wireless is:

02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express)(rev 01)

Command iwconfig show my lan, but not wifi.

Command uname -r output:

4.2.0-36-generic

And ubuntu 14.04 64bit.

Advices I've found on the net didn't help, ready to provide any output, hope for your help ;)

Thanks. Regards.

Update: Output for:

lspci -nnk | grep -iA2 net; rfkill list all

Is there another switch on the computer to enable/disable wifi? The rfkill results show a hard block which is usually caused by a switch and can't be fixed with FN combos in most cases — Jeremy31, Jun 06 '16 at 22:38
I don't see it visually, maybe it can be a jumper on the motherboard ? — Lazyexpert, Jun 07 '16 at 10:49

My Lenovo G50 has an airplane mode button (airplane icon on F7 key). Hitting Fn+F7 turns off my wifi. That might explain his wlan "hard blocked" status.

I would first check your restricted drivers in the software sources settings window. Then I would boot into a live disk of Ubuntu (if your system was upgraded) or Fedora and see if either identifies your wifi and works. If neither works, and you have an extra HDD and a windows disk, try installing that on the extra drive and see if windows can use it after installing the driver (more of a computer shop test).

If none of that works and your WiFi did work at some point, then you may have a bad WiFi card. You could go to a computer shop and ask to try any extra that they have (they have a bunch) and to buy whichever works. Don't let them take it into the back, and swap it out on the counter. It is faster and they will charge extra just to walk it into the back.

Since this is a Lenovo laptop that uses the ideapad_laptop module, do the following as a temporary solution

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

and reboot

The ideapad_laptop module has a bug that incorrectly reads the rfkill state on some Lenovo computers. The kernel developers have added a quirks table to the module so that rfkill will work correctly.

I may be able to make a better solution with the results from

sudo dmidecode | grep -i version

Please edit your answer to add the result

Did the blacklist work? I don't remember seeing this issue with a G series before. Is there a harware switch on the laptop? – Jeremy31 Jun 09 '16 at 15:00
Nope, black list didn't help. I don't see hardware switch visually, it should be in the outer space, right? And maybe this info might help: I've reinstalled Ubuntu couple days ago, and during install process Ubuntu was able to use WiFi without any dances... – Lazyexpert Jun 10 '16 at 06:58
Have you gone into BIOS and reset to defaults? – Jeremy31 Jun 10 '16 at 09:23
