“Is your laptop ASUS X450J Series??”
“Do you install Linux in your ASUS X450J Series??”
“Your wireless is detected, but it can’t enable??”
“When you enable it, it come back to disable??”
“Do you want to solve it ?”
If yes, you got a right place :-).
Last year, I bought a laptop Asus X450J series and when i try to install Linux in my laptop everything has run well, system running well, desktop well too, wireless detected too. But when i try to enable it, it can’t be enable. I installing any distro linux in my asus like openSUSE, Ubuntu, Kali Linux, elementaryOS, and etc but it can’t be enable
Oh my god, it’s wasting my time haha. Because i have a urgent job. So i ask to Facebook group of “openSUSE Indonesia Community“. Because, my desktop is using openSUSE Leap 42.1 RC. I am suspicious, is this problem came because i am using openSUSE Release Candidate?
So, the problem is simple because linux kernel detected that wireless has a duplicate driver, you can check it by rfkill command. If you don’t have, install it :
Ubuntu/Debian/elementaryOS :
apt-get install rfkill
openSUSE :
zypper in rfkill
After install you can check it using this command :
There are 2 wireless drivers and they are duplicated. So remove one of it. Logically, the laptop is asus, why linux kernel detect it as acer driver ? hahahaha
Remove acer wireless with the following command :
modprobe -r acer_wmi
And VOILAAA!, try to enable your wireless and you can detect any WiFi or Hotspot near you.
But the problem is, it’s not permanent. When you reboot your Laptop, the wireless driver duplicate again. To solve it, edit /etc/modprobe.d/50-blacklist.conf file as root. Add the following scrip at the bottom file :
blacklist acer_wmi
Okay, try to reboot your computer. If your wireless can’t be enable again. You can contact me :-D.
Good luck 😉

Thanks for this helpful article. This trick worked for my ASUS X450JN. Unfortunatelly the wireless function dropped again in the next day without clear reason even after make the configuration to the default (delete /etc/modprobe.d/50-blacklist.conf and rebooted). When I try to “rfkill list all” again, the phy0 was gone. It’s just acer_wireless with soft_blocked : yes status. Could you please share your experience? I’m afraid it’s hardware problem coz it’s also happening when switching to W10 OS.

Hi Rizal,
Yeah, i suspect the problem happen because your hardware problem. Because it’s not happened to me, i also using dual boot with W10, but it running well until now.
Below is my rfkill output :
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Have you try to use another OS?
