No network connection on new installation (BCM43142)[Solved]

Post by Disciple »

Hello Everyone,

So I decided to give Linux Mint a go. I used these instructions to dual boot Win 10 and LM 17.2 on my laptop. It seemed to install OK.

Unfortunately, I've got no wifi/network connection on my installation, though everything else seems to work (ie is stable, loads up etc.).

From browsing the forums here, I get the impression the problem might be with the Broadcom wifi adapter on the laptop. Though I wonder if I did something wrong with the installation or something.

As I've never used Linux before I simply don't know enough to resolve the issue, or know what advice is worth following.

Any help is appreciated.

[Edited to add BCM43142 to the title]

I ran inxi -Fxz, the output is below.

Hello, Disciple.

Try Linux Mint Driver Manager from the Linux Mint Menu and see whether it offers a better driver for your Broadcom BCM43142. The current driver bcma-pci-bridge does not seem to be a good choice (I know the installer chose it, not you.)
In case Driver Manager should not solve the problem, you may have a look at this Askubuntu thread, Drivers for Broadcom BCM43142 on Ubuntu 14.04 (Trusty Tahr) - Note: Linux Mint 17.x has been built on Ubuntu 14.04 Trusty Tahr. This is why what works on Trusty Tahr is not unlikely to work on Linux Mint 17.x as well.

HTH,
Karl

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-headers-generic

Thanks for the replies.

I've checked the Driver Manager, and there does not seem to be anything I can do with it (the adapter is listed as inoperative and there are no options - but like I said, I'm very new to Linux, so maybe I missed something).

I'll check through the commands given and see if I can get them to work.

Thanks.

I still have no luck getting this working.

@Karlchen, Driver Manager lists the adapter as 'This device is not working' and 'Do not use this device' is currently checked - attempting to switch it to the driver does nothing. No other drivers are listed.

Are other drivers part of the installation?


@Jungle_boy, unfortunately inputting those commands has not yielded a solution, the final output is: "FATAL module wl not found". Thanks anyway, but I don't know if I'm doing something wrong myself.

Is "dpkg -l | grep bcm" a single command or two? I'm too new at this to understand the conventions.

It generates nothing as a single command.

Try

Code: Select all

dpkg -l | grep -i broadcom
Use the Select all above the code to highlight the command, CTRL + c to copy, then in terminal you can paste with CTRL + Shift + v

I ran

Code: Select all

dpkg -l | grep -i broadcom
through the terminal - still generates nothing.

Choose a mirror site from http://packages.ubuntu.com/trusty-updat ... e/download to get a driver for the wifi. Just double click on the file once downloaded to install

VICTORY!

Thank you, JeremyB!

The download sorted the problem, and I'm now typing this out with my shiny new Linux Mint installation.

Thanks.
