My guess is that there is some minor difference in the way bluetooth is handled in the distros and it entered an unspecified state.Managing Wireless LAN on Command Line in Linux
None of the GUI controls in any of the distros were able to switch it on again. Whenever I clicked it on, it immediately moved back to off position This has happened to me before! I have had this happen to me on two different computers. First time was several years ago; so long ago that I couldn't remember how I fixed it then! As far as I recalled I just played around with rfkilland then suddenly it worked. But, to my annoyance, for some time I haven't been able to solve this - google didn't help me.
I kept trying to unblock or block-then-unblock bluetooth using rfkill, but nothing happened. Status was always "Soft blocked: yes". Switching the hardware flight-mode button on and off didn't help either. Below is command line of my attempts:. I'm using Debian 9. Just this evening I stumbled upon the "solution" which I would characterize as a work-around for a peculiarity bug? It seems rfkill sees the bluetooth radio as soft-blocked when listing but not when asked to unblock But when the "all" target is used, it just goes ahead and changes the state of every radio without judging if they are already unblocked.

However, if you have Raspbian desktop you can use the upper right-hand connection control icon to enable Wi-Fi. If you are using the command line only distro, you can utilize raspi-config and you'll find Wi-Fi settings under Network Options.
Our universal method does not use raspi-config or the connection control icon in the GUI. This will also work over SSH. Seriously, you are done. You can stop reading if you're busy and need to get on with your day. By issuing this command, we ensure the interface will always be enabled.
Our next command does all the magic to get connected to Wi-Fi in a single statement. Replace 'ssid' and 'password' with your Wi-Fi ssid and password. You can see our new entry.
Our pre-shared key has been encrypted! You can edit this file and remove the un-encrypted commented out psk if you'd like. At this point we are done. After some time has passed the Wi-Fi changes we made will take effect. Your browser does not support the video tag.

In this post, I will show you 7 ways to disable your Wi-Fi forever until you reverse your changes Most of them will work on any operating system, but I only tested on Raspbian.
As I already showed you half of the first solution, I will start with this one In introduction, I gave you one command to disable temporarily your Wi-Fi interface. Your Wi-Fi adapter will now stop directly at each boot, so you are sure to use the Ethernet cable all the time To bring the Wi-Fi up again temporarilyuse: sudo ifconfig wlan0 up Or remove the line in the crontab to enable it at each boot. The third way to disable Wi-Fi on your Raspberry Pi is more extreme On Debian, as on many other distributions, modprobe is a program that load kernel modules on boot You can choose to disable some modules, like the Wi-Fi drivers for your Raspberry Pi:.
Then reboot your Raspberry Pi with an Ethernet cable pluggedand you will not see the Wi-Fi adapter on the next boot Remove the two lines from the file to reactivate it.
Another method you can try, is to edit the Raspbian configuration file The good news is that you can even do this on a fresh Raspbian SD card, to disable the Wi-Fi directly. Here is the command use this in a terminal if you are on Raspbian Desktop : sudo modprobe -rv brcmfmac This command will also remove brcmutil and cfg automatically. The block command is persistent after a reboot To enable Wi-Fi or Bluetooth, use the unblock command like this: sudo rfkill unblock wifi sudo rfkill unblock bluetooth.
Finally, the last solution I want to show you, is to use systemctl to stop the wireless services Systemd is the service manager on many Linux distributions, and you can use systemctl to see and control each service state. I think we have seen most of the solutions available I hope you found one that works for you, and that this post was helpful. Average rating 4. Vote count: 5.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. This works fine so far. I was just having this problem and nmcli r wifi on solved it. NetworkManager was killing the wifi after startup finished which is why startup script solutions didn't work for me. A faulty driver or other kernel module can lead to connectivity loss.

WiFi soft-blocked by rfkill on startup Ask Question. Asked 5 years, 3 months ago. Active 10 days ago. Viewed 3k times. However, I'm having trouble with the WiFi being soft blocked by rfkill on every startup.
Whatever is causing rfkill to block WiFi probably happens after rc. I can see the network on my smartphone as well, but it disappears shortly after showing up. Changing the line to phy0 0 or phy0 1 doesn't solve the problem. Also the file doesn't seem to change at all, so whatever stores the state doesn't work. What worked for me was the following line in rc.

Raw Blame History. Introduction 2. Implementation details 3. Kernel API 4. Userspace support 1. Introduction The rfkill subsystem provides a generic interface to disabling any radio transmitter in the system. When a transmitter is blocked, it shall not radiate any power. The subsystem also provides the ability to react on button presses and disable all transmitters of a certain type or all.
This is intended for situations where transmitters need to be turned off, for example on aircraft. The rfkill core provides API for kernel drivers to register their radio transmitter with the kernel, methods for turning it on and off and, letting the system know about hardware-disabled states that may be implemented on the device.
The rfkill core code also notifies userspace of state changes, and provides ways for userspace to query the current states. See the "Userspace support" section below. Kernel API Drivers for radio transmitters normally implement an rfkill driver.
Platform drivers might implement input devices if the rfkill button is just that, a button. If that button influences the hardware then you need to implement an rfkill driver instead.I've encountered trouble trying to activate my wlan0 interface and I was wishing that someone here might be able to help me. The Soft block remains unchanged regardless of me trying to unblock all with rfkill. It is worth mentioning that this problem has remained persistent throughout multiple linux distributions that I've tried on my laptop.
The Wifi works fine in Windows 7 but as soon as I switch to any linux distro it stops working. Check if you can unblock your phy0 again when you first disconnect the wire from the ethernet card or set you eth0 interface down if it doesnt work.
As I can see you have two wireless interaces, when i see only phy0 with rfkill, it's maybe your hp-wifi that force to disable phy0 interace. I think if you blacklist the driver it might allow phy0 to be enabled. This worked! You're welcome. Atom topic feed. Arch Linux. Index Rules Search Register Login. You are not logged in.
