Connecting Linux Mint to WiFi network

  • I just installed Linux Mint 17 (MATE) on an old laptop and everything works amazing, however I can't seem to get it to connect to my WiFi network. All my other computers can get access, plus, before when the laptop has Windows XP, it could also find and connect. Is there a way to check if it's even detecting the correct network? If so, how would I set up a proper connection to the network?

    There is nothing wrong with my network nor the laptop, so it must be Mint's fault.

    Edit: Output of iwconfig:

    lo       no wireless extensions.
    
    eth0     no wireless extensions.
    

    Output of lspci -nn | grep 0280:

    02:04.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)
    

    Please [edit] your question and add i) the output of `iwconfig` and ii) the output of `lspci -nn | grep 0280`.

    @terdon Edited and added.

    geez. fought with this issue for an hour. Alt-F2 enabled wireless. But it was color coded for the windows machine it used to be. Fn_F2 blue. grrr...

    This answer assumes that you can connect your machine to the network using a cable and so get internet access. If that assumption is wrong, let me know and I'll modify this.

    You need to install the driver for your wireless card. The driver support table of the Linux Wireless page lists it as supported so you should be able to get everything working by simply running:

    sudo apt-get install firmware-b43-installer
    

    If this does not work leave me a comment, you might need to tweak it a bit.

    Further reading:

    Thanks, I got the driver installed with an old cable I found laying around. Still, not sure how I can set up the WiFi network itself. I also did `iwlist wlan0 scanning` which told me: `wlan0 Failed to read scan data : Network is down`

    @GotGaming_ did you reboot? Did the `iwconfig` output change?

    Yes, I did and it now shows `wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off` + the same 2 it showed earlier

    @GotGaming_ great, so it's working. Now you need to connect to a network. You should see a little icon on the task bar (NetworkManager) that should let you choose a network to connect to. Also right click on the icon and make sure that wireless is on.

    Oh I'm a dummy, I had WiFi turned off xD Thank you so much, I couldn't have done it myself.

    @terdon Without Ethernet, one can get b43-fwcutter from packages.ubuntu.com, and the driver from a computer with internet access. This post is useful for this scenario: http://askubuntu.com/questions/730799/installing-fimware-b43-installer-offline
