wireless switch turned on but showing hard bloked: yes

Do you dual boot the system?
Is there a switch to turn the wireless off and on?

Hi Andrew,

No, the laptop was shipped with Win7 on it, but I removed everything and installed only Ubuntu 12.04.

Yes, there is a switch which is showing turned on(glowing bluish white). If it was turned off, it should have shown a red glow light.

Regards,
swaroop

Andrew, just to let you know that the Fn key (F12) which is used to turn wireless on/off isn't working in Ubuntu.

Check the bios settings some laptops, Dell for example, have settings for soft switches in the bios. If you can check the wireless is turned on in the bios and disable the switch

Hello ,

can you please provide some more info ?

Open a terminal and give the results of bellow commands :

lspci -nnk | grep -iA2 net

lsmod

sudo lshw -C network

Thanks

Hi,

I will definitely provide the required info, but I'm now stuck with another problem. I have VirtualBox installed and I wanted to share the 'Downloads' folder from my host OS. So, I had to install the samba. During installation, I received an error, but tried installing again, it got installed. And when i rebooted the machine, its showing me a message 'The system is running in low-graphics mode' and I am unable to get out of it. Please help.

Nick - once i get back to normal screen, I will provide the info. Sorry for the delay.

Regards,
swaroop

Please open a separate question for your problem with Virtualbox. By limiting each question to one problem its much cleaner for people trying to find solutions to their own problems. Also by asking a separate question about Virtualbox its more likely to be read by someone with more experience of Virtual box.

When you get back with answers to Nick's questions we will try to help you further with your network problems.

Hi Nick,

Please find the output of the commands below:

Hi ,

do you have USB WIRELESS DONGLE attached ?

If yes , then Remove it and reboot your pc without it.

Then open a terminal and try

sudo ifconfig wlan0 up

If nothing happens give the results of bellow commands

dmesg | grep -ie iwlwifi -ie wlan -ie net -ie firm

nmcli nm

Thanks

Hi Nick,

I removed the dongle, rebooted and here's the output you want.

Hi ,

I think your problem listed somewhere in above messages.

Try these commands in terminal and tell me if WiFi awakened.

  - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

sudo modprobe -rvf hp-wmi

sudo rfkill unblock all

sudo ifconfig wlan0 up

nmcli nm wifi on

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

If nothing happen after last command , then try again the switch (Fn+F?)
and wait 5-10 secs to see.

If nothing happens again , then give the results of

- - - - - - - - - - - - - - - - - - - - - - -
rfkill list all
- - - - - - - - - - - - - - - - - - - - - - - -

Thanks

try:

echo "options iwlwifi 11n_disable=1" | sudo tee -a /etc/modprobe.d/iwlwifi-disable11n.conf > /dev/null
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

Does it now work ok?

Thanks a ton Nick. It solved my problem. The wifi is turned on now.

Just one last query. I find the wireless is very slow when power cord connected. Is it because the power management is on then? If I turn the power management off, will it effect the connectivity? And will it effect the machine (I mean what would happen if I turn off the power management)?

Thanks again.

Regards,
swaroop

Yes this can be corrected too:

Open a terminal and give this command

______________________________________________

gksudo gedit /etc/modprobe.d/iwlwifi.conf

_______________________________________________

it will open an empty document , copy-paste this inside

________________________________________

/options iwlwifi 11n_disable=1
________________________________________

save the document and reboot your PC .

Thanks
/

Correction :

WITHOUT the slash /

I will give again the commands here

1st ..

gksudo gedit /etc/modprobe.d/iwlwifi.conf

2nd...

at the empty opened window you add this line inside

options iwlwifi 11n_disable=1

Save the document and restart your PC.

Thanks

My way does it ion one command rather than messing with gedit and such ;)

Thanks for the great support Nick. Its truely appreciated..:)

Hi Nick/Andrew,

The wireless and bluetooth options were enabled after I executed the commands given by Nick. Then I also run the iwlwifi command given by Nick. Saved it, restarted the PC, but found that the wireless is again turned off.

So, I ran the commands given by Andrew, but doesn't work.

What next to do?

Regards,
swaroop

Ok ,

Open a terminal and execute this command

echo 'blacklist hp-wmi' | sudo tee -a /etc/modprobe.d/blacklist.conf

reboot your PC and see if problem solved.

Thanks

Bad luck. The wireless is still turned off and it also took away my bluetooth indicator. Now my rfkill command only shows the wifi

swaroop@roobuntu:~$ rfkill list all
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes
swaroop@roobuntu:~$

Its not showing the bluetooth anymore.

In the meantime when the bluetooth and wireless were enabled, I tried transferring a file from PC to my HTC phone. So, I can say that the bluetooth was working fine.

Hey Nick, I noticed my wireless indicator turned red. That means the wifi is turned off physically. So, if I run the command given by you initially, will that work good? I tried enabling it by using Fn+F12 but the light didn't turn bluish white. So, its not working that way.

No problem , we can revert (undo) the last change ..

Do this now

Open terminal and give

gksudo gedit /etc/modprobe.d/blacklist.conf

find the line we added before : (it will be in the end)

blacklist hp-wmi

and delete it.

Then save the document and reboot again .

Post back here the the results of

rfkill list all

Thanks

Also give the results of

ls /etc/modprobe.d/

Thanks

Results:

The wireless light turned bluish white again but showing disabled by hardware switch in indicator panel.

Bluetooth came back but status in indicator panel is disabled

Hi ,

first of all remove the one iwlwifi...conf . Not needed both..

sudo rm /etc/modprobe.d/iwlwifi.conf

Then try again the commands I gave you before.. and see if WiFi turned on ..

sudo modprobe -rf hp-wmi

sudo rfkill unblock all

sudo ifconfig wlan0 up

nmcli nm wifi on

--------------------------------------------------------

IF and ONLY IF wifi turned ON with above commands , then do as follows.

Run in terminal

gksudo gedit /etc/rc.local

and BEFORE the line exit 0

add bellow lines with this order

(sleep 5 ; modprobe -rf hp-wmi) &
(sleep 7 ; rfkill unblock all) &
(sleep 9 ; ifconfig wlan0 up) &
(sleep 11 ; modprobe hp-wmi) &

Save the document and reboot again to see if Wireless works.

Thanks

The wifi and bluetooth were turned on by the commands. So, I added the lines and then rebooted. Just when I logged in by providing the profile password, the system showed me a notification "Wifi networks available. Choose a network from the menu". But before I could click and expand the menu to check wifi networks, the bluetooth and wifi got disabled and its now showing that its wifi and bluetooth are disabled by hardware switch.

Just asking, is it a possibility that I am running the commands with my dongle connected. So, things are happening temporarily and getting cleared off when restarted?

The commands we added in rc.local executed at the startup of the system.

Reboot WITHOUT the dongle attached and we will see.

Thanks

No, the dongle isn't affecting the status. I removed it, the system notified me I'm offline. Rebooted, it showed me the same message - Wifi network available, but things are disabled.

Ok ,

Lets change the lines inside rc.local a little ..

Open the file with

gksudo gedit /etc/rc.local

the lines we added before are these

(sleep 5 ; modprobe -rf hp-wmi) &
(sleep 7 ; rfkill unblock all) &
(sleep 9 ; ifconfig wlan0 up) &
(sleep 11 ; modprobe hp-wmi) &

add one more line between sleep 9 and sleep 11 and we change the time too .. make the lines like this

(sleep 5 ; modprobe -rf hp-wmi) &
(sleep 7 ; rfkill unblock all) &
(sleep 9 ; ifconfig wlan0 up) &
(sleep 11; nmcli nm wifi on) &
(sleep 30 ; modprobe hp-wmi) &

save the document and reboot Without the Dongle.

Thanks

Outstanding!! The wireless and bluetooth were enabled for about few seconds and I could expand the menu to see they are actually enabled and also it listed two wireless networks that I have in range.

Nick, how to make the lines permanent in rc.local to solve the problem?

Great!! its working now. Both wifi and bluetooth are enabled now. Thanks a lot for prompt support.

When I restarted and tried to connect with the dongle, it wasn't connecting. So I restarted the networking service and it worked. I have wifi at workplace, so I'll check the status there tomorrow and let you know if its working fine.

Its almost 4am in the morning and I should go to sleep now..:D . What time is it at your place?

I hope you not come tomorrow and change the question to => Open. ha ha..

Glad we solved your problem. I wish to remain solved.

Have a good night. (morning).

Oh , and please mark the answer that solved your question.

This will help future users with same problem as yours , to find the correct answer (that solved the problem) more easily.

Thanks

Thanks NikTh, that solved my question.

Thanks Nick. The wifi is working now. I just came to office and checked. Hope the connection remain consistent. If not, you are always there to solve the issue I'm sure...:)

Take care.
