Wireless worked fine until VirtualBox make my laptop freeze. I had to unplug it. After reboot, when I use wifi-menu, no network is available. I have all my drivers, and all interfaces are DOWN. Whenever I try to turn one on, I have an error message : SIOCSIFFLAGS: Operation not possible due to RF-kill
Arch Linux - No network available after crash

If you typerfkill listit will probably show that your wifi is blocked. Unblock it withsudo rfkill unblock wifiIf rfkill is not installed on your system, you can install it withsudo pacman -S rfkillIf you don't have internet access at all, you should still be able to do this by hand. See if you can find those files on your computer:/sys/class/rfkill/rfkill0/hard/sys/class/rfkill/rfkill0/softAll they should contain is 0, which means they are not blocked. If they contain 1, change it to 0. Maybe rfkill0 is not your WiFi device, but e.g. Bluetooth. Then change rfkill0 with rfkill1 in the path's above.I'm not sure if you have these path's on your system, since you haven't installed rfkill. I uninstalled rfkill and still had them, but of course that's no guarantee. In any way these are just softlinks and if they are not there, we have to find the files somewhere under /sys/devices/.
