WIFI issues Broadcom

Hi, Lenovo Fn/F5 keys toggle wireless card on and off. Enter code...

rfkill list all

*IF wireless shows hardblocked Yes, press Fn/F5 only one time and repeat code...

rfkill list all

to see if it unblocked.

please also post..

grep -i blacklist /etc/modprobe.d/blacklist.conf

then look at this thread...post #8

Hi ,
this is weird , because bcma driver seems to support your wireless card

alias: pci:v000014E4d00004727sv*sd*bc*sc*i*

but try what @Hadaka suggested .
First install linux-headers-generic and the install bcmwl-kernel-source , @chilli555 is one of the wireless masters here
Thanks

Hi ,

the fn/F5 combination just influenced the 'soft blocked' part and did not change the 'hard blocked'

tyatyi@tyatyi-Lenovo ~ $ rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
tyatyi@tyatyi-Lenovo ~ $ rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: no

tyatyi@tyatyi-Lenovo ~ $ grep -i blacklist /etc/modprobe.d/blacklist.conf
blacklist evbug

blacklist eepro100
blacklist de4x5
blacklist eth1394
blacklist snd_intel8x0m

blacklist garmin_gps
blacklist asus_acpi
blacklist snd_pcsp
blacklist pcspkr
# from being initialised (Ubuntu: #297750). Blacklist so that the driver
blacklist amd76x_edac

I tried also the suggestion on the different thread, I installed the headers and the driver according to the codes. But no change, after reboot it still shows, that wireless disabled by hardware switch... although the physical switch is clearly ON

sudo apt-get install linux-headers-generic sudo apt-get install --reinstall bcmwl-kernel-source sudo modprobe wl iwconfig

Hi, delete the wireless infotext file in your home folder then copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks

Just as a temporary experiment, please try:

sudo modprobe -r ideapad-laptop
sudo rfkill unblock all
sudo rfkill list all

Now have we cured this?

0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

Thanks.

There are several Broadcom devices that are covered by multiple drivers, brcmsmac, b43, wl, etc. The key is determining which works best. In this case, I believe bcmwl-kernel-source is optimal for 14e4:4727. Its installation handily blacklists everything else.

Hi

attached is the file requested.

the commands did not change the 'hard locked' part:

tyatyi@tyatyi-Lenovo ~ $ sudo modprobe -r ideapad-laptop
tyatyi@tyatyi-Lenovo ~ $ sudo rfkill unblock all
tyatyi@tyatyi-Lenovo ~ $ sudo rfkill list all
2: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes

Thank you for trying to help

Sticky little problem you have there! You might check here: http://glonek.co.uk/linux-mint/wirel...-hard-blocked/

If I reboot the machine and press the WiFi button on the laptop ONCE sometime before linux boots (took me 3 tries to get the timing right – needs to be somewhere between the BIOS and OS boot… hard to say) – then the phy0 hard block will go off! I can use my laptop WiFi again!

You might also reset the BIOS to default. We have seen a few cases where this helps.

Hi, here is yet another link with a like hardblocked on a Lenovo
looks like a bios reset and a blacklist add.

http://askubuntu.com/questions/14378...ch-lenovo-b460

hope this helps.

Hi,

it seems I am hopeless. I did all steps, I reset BIOS, I checked there under settings: Wireless is enabled. I tried the FN/F5 game as well during boot. Nothing.
I really think that the hardware switch might be faulty and not switching back correctly...
Unfortunately wireless still shows as disabled...

However now this results shows the following , two times wireless and one is yes, yes

0: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes
1: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
2: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: no

Hi ,
please try this

sudo modprobe -rvf ideapad-laptop

now try again the wireless switch (Fn+F5) .
Working ?
Thanks
