Need Help Installing Wireless Driver on Fedora 20! Any Help is Seriously Appreciated!

Hi Everyone,

I just installed Fedora 20 on my Lenovo B5400 laptop! Obviously the first thing I noticed was that there was no wireless connection. I have installed the exact same ISO of Fedora on my older laptop and the wireless was working so having no knowledge in commands other than updating and upgrading, I need help installing the wireless driver for this laptop pretty please.

When I type into terminal: lspci, the result for the wireless part is;

- 04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

If there is anything else that you would like to know, do let me know.

Many Thanks
Alan.

More about installing wireless driver fedora appreciated
  1. post output of dmesg to pastebin.com please
    this driver should already be in the fedora 20 kernel.. maybe you just need a firmware

  3. Best answer
    First update your system.
    su -c 'yum update'


    Latest kernel for fedora 20 is 3.16, you are running old 3.11 version. Maybe 3.11 predates the kernel driver for your card.
    You can check what kernel version with
    uname -a

    or
    uname -r
  4. You can also check the contents of folder:
    /usr/lib/firmware/rtlwifi/

    You are looking for the firmware file:
    rtl8723befw.bin

    If this still does not exist after update then you will have to build the driver from source.

    git clone http://github.com/lwfinger/rtlwifi_new
    cd rtlwifi_new
    make -j
    sudo make install
    sudo modprobe rtl8723be #(or reboot)


    in addition Ubuntu 14.10 has the 8723be driver but not 14.04

  5. Thank you so much Skittle for all your input, was really useful! It took a while to update since I have slow internet but it seems to be working fine for now after updating finished. I understand what you mean too by building the driver too, but all seems okay now and the folder you were referring to is here: http://i.cubeupload.com/9HE83C.png - towards the center of the picture is the wifi driver folder I'm presuming, so it's a good sign :D

  6. Also one more thing Skittle, I noticed on my touchpad that when I tap it, it doesn't click anything, like you know the way you tap the touchpad and it clicks whatever you want to click but that feature is not working on my touchpad, any ideas? :)

  7. Yes all touch pad settings are configurable via "synaptics" the xorg touch pad driver.

    Conviently there is a nice interface that makes this easy to test different settings. "synclient".

    The archwiki has probably more information than you want, but it is good place to look.
    Probably you want to look at the synclient options "TapButton"
    https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Configuration

    This will show you current synclient parameters:
    synclient -l
  8. Hi again :D So today in uni, I noticed my wifi dropping out ALL THE TIME! I just ignored, restarted computer, worked again, stopped working, restarted, still didn't work, restarted, worked again, just a pain really! So I'm trying to build the driver now and see if it will fix it, I hope it will anyway :) But when I get to the: make -j part it outputs this error:

    # make -j
    make -C /lib/modules/3.16.3-200.fc20.x86_64/build M=/root/rtlwifi_new modules
    make: *** /lib/modules/3.16.3-200.fc20.x86_64/build: No such file or directory. Stop.
    make: *** [all] Error 2

    Any ideas? Or any ideas of why the wifi just stops working all of a sudden?

    Thanks again :)

    as far as I can tell its just sort of a buggy driver.
    Instead of rebooting you can just reload the driver
     sudo rmmod rtl8723be && sudo modprobe rtl8723be


    As for compiling the driver: You just need to have installed the kernel headers.
    sudo yum install kernel-devel kernel-headers


    https://bugzilla.kernel.org/show_bug.cgi?id=83641#c1

    (By the way it is bad practice to be constantly running as root, you can potentially break your installation if you accidentally overwrite a file or something, or even just a typo)
