I have a Asus K501UQ with an Intel which worked fine on my Windows partition. I've put on Elementary OS (Loki) but the card is disabled and I'm not able to enable it.

rfkill list all

returns

0: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
3: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

So perhaps it's because the interface is hard blocked but I'm not sure why there are two Wireless LAN interfaces listed here.

lshw -class network

If I perform:

sudo sudo ifconfig wlp3s0 up

I get the error:

SIOCSIFFLAGS: Operation not possible due to RF-kill

I'm assuming this is because phy0 is hard blocked. As far as I'm aware there's no physical switch on my laptop and it works if I boot into Windows. I've hit the limit of my knowledge, any help would be greatly appreciated.

  • Can you edit your question and add the output of "lsmod | grep asus"? – bitseater Jan 21 '17 at 23:15
  • Pleased to say this issue wasn't present on Juno. – samblake Jan 12 at 11:58

It is likely you need to use the wapf parameter in asus-nb-wmi. The kernel source code tells us this about wapf

/*
 * WAPF defines the behavior of the Fn+Fx wlan key
 * The significance of values is yet to be found, but
 * most of the time:
 * Bit | Bluetooth | WLAN
 *  0  | Hardware  | Hardware
 *  1  | Hardware  | Software
 *  4  | Software  | Software
 */

Using wapf=4 seems to work for most computers with hard block issues and we can apply this with

echo "options asus-nb-wmi wapf=4" | sudo tee /etc/modprobe.d/asus-nb-wmi.conf

Reboot and see if wireless works

  • what is asus-nb-wmi? what would be the equivalent for other laptops? how to get that specification? I am looking for a more general solution than just for Asus – user170 Apr 18 '18 at 12:50

I have this problem too when I disable physically my WiFi connection (Hardware blockage) , or just simply by turning WiFi off by clicking on the toggle in the WiFi list connection ( Sfteware blockage)

In both cases, I was using this command to solve the problem

sudo rfkill unblock 0

but I am not sure if it is going to help you since it sounds that your WiFi card is unblocked.

Used my iPhone to get a temporary Internet connection, and found this site: http://www.edimax.com/edimax/download/download/data/edimax/global/download/for_home/wireless_adapters/wireless_adapters_ac1750_dual-band/ew-7833uac

Used the Linux drivers for my ASUS 1900 AC68 USB device and worked on the first try. Before I updated the driver, I performed all of the OS updates through my iPhone, just in case that makes a difference.

  • you mean you installed the driver for a connection to an Edimax wifi rooter? what's the relation with the question above? – user170 Apr 18 '18 at 12:53

Try "nmcli radio wifi on". It works for me.

  • Thanks, this seems to be still an issue on Juno.... – Phil Roggenbuck Aug 10 at 15:44

This worked for me: I held down the orange wifi button above the keyboard (this is on a Compaq) near the power switch and toggled the wifi switch in network settings. Wifi button turned blue and wifi options showed up in Network Settings. Not sure it will work for everyone, but worked for me!

BTW, this relates to the answer by Subham Patel.

All those facing Hard Blocked problem just press the wifi button on your keyboard! It will work!
