Can't get BCM43142 to work with 17.1 Cinnamon x64

necromorph · Post by **necromorph** » Tue Feb 03, 2015 3:31 pm

Recently installed 17.1 Cinnamon x64 and all seems good, except for WiFi. The system is a Lenovo G510 with a Broadcom BCM43142. I initially tried the bcmwl-kernel-source from 'Driver Manager', to no avail. I also tried manually installing the driver from :

http://www.broadcom.com/support/802.11/linux_sta.php

following the instructions at : http://www.broadcom.com/docs/linux_sta/ ... 23.248.txt

Confirmed that Wireless is enabled in the BIOS. Tried resetting BIOS to defaults as well as re-inserting the CMOS battery.
Previously had Windows 7 on this and WiFi worked on that. Currently, Mint is the only OS installed.

I also tried updating the kernel to 3.13.0-45 & 3.16.0-30 but that didn't help, so reverted to the default 3.13.0-37.

Have added the following lines to the /etc/modprobe.d/blacklist.conf file :

blacklist ideapad_laptop
blacklist ssb
blacklist bcma
blacklist b43
blacklist brcmsmac

blacklist bcm43xx was added in there by default by Mint.

The F7 key is the WiFi/Bluetooth toggle, but all that does is change the 'Soft Blocked' status to yes/no. The Hard Blocked status remains 'yes' no matter what.

Post the full output of

and have you rebooted with the ethernet cable disconnected since adding ideapad_laptop to the blacklist?

necromorph · Post by **necromorph** » Tue Feb 03, 2015 8:38 pm

Since installing Mint, I've been using USB tethering via my phone - never connected this system via the ethernet jack. That being said, I have rebooted while having the phone disconnected. I think the only difference I've noticed is that I didn't have to run 'ifconfig eth1 up' so that the adapter doesn't show as disabled when running 'lshw -C network'.
I also noticed that when I had installed the bcmwl-kernel-source driver initially, the adapter would show up as 'wlan0', whereas now it shows up as 'eth1'. I was able to run 'iwlist wlan0 scan' before (which produced no results) but now when I run 'iwlist eth1 scan', I see "eth1 Interface doesn't support scanning : Invalid argument"

Here's lsmod :

will work

I've tried that, and it only changes the 'Soft Block' status. Hard Block still remains 'Yes'.

Post by **JeremyB** » Wed Feb 04, 2015 9:46 am

I wonder if there might be something wrong with the driver you installed. Open synaptic package manager, search for broadcom, select installed from the left side of the window and right click on anything called broadcom-sta and select uninstall then in terminal

Code: Select all

apt-get install bcmwl-kernel-source

None of the broadcom-sta packages seem to be installed as per Synaptic. I had manually compiled the drivers & installed them following the instructions at :

http://www.broadcom.com/docs/linux_sta/ ... 23.248.txt

How do I revert those changes? By running rmmod or modprobe -r ?

Choose a mirror site to download and double click the file to install. If it tells you another version is available choose to install the downloaded one and reboot when done

Installed the driver from the URL you provided. After the installation completed, I disconnected my phone and rebooted.
Hard block still shows Yes and scanning produces 'No scan results'
Would you like to take a look at outputs of certain commands?

You might need to edit the blacklist to remove ideapad_laptop and reboot. I have done some searches on your model and cant find any case like yours using linux and I have a G710

Removed the ideapad_laptop from blacklist. The bluetooth interface started showing up again, but no luck enabling either that or wireless.
I do appreciate your inputs & time. Let me know if there is anything else you can think of.

Is this wifi card a replacement? You could power off and remove the bottom, pull the card then put everything back together in case it isn't properly inserted.

It is the original card that came with the system. It was working fine on Windows - no problems at all.
I disconnected the card, removed it completely, re-seated it & re-connected. No change.
I revisited this thread : http://askubuntu.com/questions/55868/in ... ss-drivers
and tried removing the bcmwl-kernel-source ; tried the b43 as suggested in the thread but with that, the card wouldn't even be detected by ifconfig or iwconfig.
I've reverted to the bcmwl now.

Search for 14e4:4365 lenovo g510 to see if you can find anything with a hard block.

Those keywords brought me to :

I tried the patch provided by the author on the above page, but that didn't work as well.

I'm going to cross-post this to askubuntu.com to see if I can get any other suggestions. Will update this thread if I manage to get it resolved.

I wonder if this might work. But only if you are dual booted with windows, I have seen similar problems but I think they were toshiba
