Wireless card has no interface name

Post by glitchg »

Hello,

I have recently installed Linux Mint 17 (Cinnamon) on my Acer notebook, and I'm in a bit of a struggle to get networking to work.
In addition to problems with wired networking (which I have detailed here), I just found out I am unable to use Wi-Fi.

When investigating the reason, I found out that the kernel is not attributing any interface name to my wireless card. Here is the output from running mintWifi.py:

As you can see, there is no interface for the wireless card. And here are the results from running inxi -Fxn:

As you can see, no interface name is attributed by the kernel to "Card-2" (my Broadcom wireless card).

I have no idea what to do, or how to solve this. If anyone could help, it would be much appreciated.

Please open a terminal window using CTRL+ALT+t and copy and paste this in using the mouse/touchpad buttons

Code: Select all

wget -N -t 5 -T 10 https://dl.dropboxusercontent.com/s/0h4ef93hjiz0dgy/wireless_script_mod && \chmod +x wireless_script_mod && \./wireless_script_mod
It should return a URL at the very end, please post the pastebin URL

Hi JeremyB, thanks for the answer.

As I said before, I have no internet connection on Mint, so I can't run wget. However, I downloaded the script manually, deleted the automatic upload to pastebin from it, ran it and uploaded the result to pastebin.

Here is the link: http://pastebin.com/CcauEPkm

Code: Select all

sudo modprobe -rv bcma
If you have wired internet on the problem machine try

Code: Select all

sudo apt-get install bcmwl-kernel-source
If not go to http://packages.ubuntu.com/trusty/amd64 ... e/download and select a mirror site to download from. Once you have the file on the LM pc in your home folder, you should just have to double click on the file to begin the install

I don't have any wired connection on the affected computer. I tried to do a manual install, but got stuck in dependency hell. I'll try to solve my wired internet issues first, and then try and change the wireless driver.

Hi, thanks for everyone's help. I finally managed to solve my wired internet problems. After doing so, I immediately installed the package suggested previously through apt-get.
After restarting the computer, wireless worked smoothly.
