One Fine Day..I don't want to shut down my computer, So, “Suspended” it,
When turned on next time ,
the problem starts,
WiFi – Not Turning ON, Its not a detection problem, or Driver not found or any thing, the whole WiFi option not turning ON, 🥴 ..???
Into Debug Mode,
Usual Restart, no result
Battery Removed Power off - ON, No result
As the "Suspend" Started the problem, trying a chance with several repeated suspends with, plug in and out the USB adaptor(Which is Tp link TL-WN725N), No result,
Reset The BIOS to default, On my HP laptop, at booting, it is
ESC -> F10 -> F9 -> set to default -> OK
, No result,Also, BIOS not have any other options for WiFi.
Now back to Ubuntu, open the terminal, from internet, understood Ubuntu got a "handy" soft suspending features to turn off connections like the WiFi and Bluetooth, so does a
rfkill list all
, that shows0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hci0: Bluetooth Soft blocked: no Hard blocked: no
WiFi got hard blocked, but how??, I’m using an HP-15 series laptop with a not working normal keyboard(it is unplugged too), using with an external keyboard.. The WiFi turn on/off keyboard keycode HP gives is
Fn key + F12
, but as I’m using external keyboard,Fn
key not in the picture anymore.. Tried combinations of allf1
tof12
possible...no result..There are no other external keys for WiFi.
Now It started to get seriously annoying, decided to go check in the dual-booted windows, whether it is affected or not, The WiFi works there as usual, with adaptor detecting from the first sight of the windows logo, but in Ubuntu, it behaves like, it never heard about WiFi.
Tried
sudo rfkill unblock all
,sudo rfkill unblock 0
(which is therfkill
assigned code for w LAN) with no results (even-though I know it is “Hard” blocked).Then I get know from the internet some settings or conflicting drivers can be blacklisted in Ubuntu, so do this
lsmod | grep hp # The results hp_wmi hp_wireless
Blacklisting
hp_wmi
and a reboot solved this issue for some people, they've listed in web, I tried the same, but with no luck.. by going to/etc/modprobe.d/
selectblacklist-hp.conf
,blacklist.conf
addedblacklist hp_wmi
-> reboot..., but no result same "Hard blocked: yes" also with theblacklist hp_wirelss
, no improvementssame
0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes
After this attempts, the only thing achieved was the
numbers
changed,now it is 1 for WiFiWhere is this
Soft blocked
,hard blocked
get stored, next that will be the concern, if I can find that file and alter the value It will be all good again,And Thankfully I founded this, based on the same problem described there, did the
cat /sys/class/rfkill/rfkill1/hard # gives me a "1" # To make it 0, with all permissions sudo -i echo 0 > /sys/class/rfkill/rfkill1/hard # gives me echo: write error: Input/output error # its fixed by hardware..no way to change
Uninstall and installs the
rfkill
...(don't know what I'm doing..😵)Now its getting lost, trying to figure out an Ubuntu reinstall or a backed up
timeshift
can solve the problem, decided to check that, plugged in a bootable USB Ubuntu -> Try before install -> check if the Wifi loads or not., No its also shown as hard blocked :- YESFinally changed the laptop-keyboard only for the sake of getting WiFi back, pressed the key
f12
with full confidence which is the hardware key for airplane mode (not only for WiFi)...still no use, that samehard blocked
is killing me..
This is where I am now, I badly need this WIFI
gets working on ubuntu, can anybody help..
