    problem realtek 8723 driver

    Hello,

    Im just trying to install ubuntu on a new computer. I installed ubuntu 12 but did not recognize the wireless device. It is a realtek 8723. I already found the drivers on other topic but I can not install them.

    When I do make I get the following error:

    make -C /lib/modules/3.2.0-23-generic/build M=/home/seldon/realtek driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012 modules
    make[1]: Entering directory `/usr/src/linux-headers-3.2.0-23-generic'
    make[1]: *** No rule to make target `driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012'. Stop.
    make[1]: Leaving directory `/usr/src/linux-headers-3.2.0-23-generic'
    make: *** [all] Error 2


    I can not find a solution

    I have already installed build-essentials and linux-headers-3.2.0-23-generic

    unname-e gives me 3.2.0-23-generic

    Anyone out there that can help me please

    Thanks

    Re: problem realtek 8723 driver

    I have already installed build-essential
    Are you sure it's all in place?
    Code:
    sudo dpkg -s build-essential
    I am very interested in your device, old driver dawg that I am. Please post:
    Code:
    lspci -nn | grep 0280
    Thanks.

    Re: problem realtek 8723 driver

    Thanks for answering

    I did as you say:

    When I do sudo dpkg -s build-essential I get:

    Package: build-essential
    Status: install ok installed
    Multi-Arch: foreign
    Priority: optional
    Section: devel
    Installed-size: 37
    Maintainer: Ubuntu Developers
    Architecture: amd64
    Version: 11.5ubuntu2
    Depends: libc6-dev | libc-dev, gcc (>= 4:4.4.3), make, dpkg-dev (>= 1.13.5)
    Description: .....


    When I do lspci -nn | grep 0280 I get

    [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8723]


    It seems the package is well installed, no idea why I can not do make.

    Thanks for the help

    Re: problem realtek 8723 driver

    I downloaded the packages here: http://askubuntu.com/questions/13963...not-recognized

    I extracted and made the files perfectly without even a warning. The only thing that may be different is that I built after sudo su:
    Code:
    cd Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
    sudo su
    make
    etc., etc.
    I don't know if the 'make install' installs the firmware properly, we'll need to look at that.

    Please try with sudo su.

    Re: problem realtek 8723 driver

    The files I am trying to install I got them from the same thread you mention.

    I also used sudo su before running make and getting the error on the first message.

    Thanks for the help

    Re: problem realtek 8723 driver

    Please try, with a wired ethernet connection:
    Code:
    sudo apt-get install --reinstall build-essential
    sudo apt-get install --reinstall linux-headers-generic
    sudo apt-get install --reinstall linux-headers-`uname -r`
    Those tickmarks are on the left side of my US keyboard on the same key with ~.

    Now try again.

    Re: problem realtek 8723 driver

    I did as you say and I still have the problem when I do make (after sudo su)

    The error is still:

    make -C /lib/modules/3.2.0-23-generic/build M=/home/seldon/realtek driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012 modules
    make[1]: Entering directory `/usr/src/linux-headers-3.2.0-23-generic'
    make[1]: *** No rule to make target `driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012'. Stop.
    make[1]: Leaving directory `/usr/src/linux-headers-3.2.0-23-generic'
    make: *** [all] Error 2

    Any other ideas? Thanks

    I am still mystified. What directory are you starting from? Is the Makefile located in the working directory?
    Code:
    ls
    I get, for comparison:
    root@LAPTOP60:/home/chili/Desktop/Forum/Seldon/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012# make

    etc., etc.
    Yikes!! By any chance, is the directory named 'realtek driver'? Linux and the terminal don't like spaces in directory names very well. If so, please rename the directory to realtek and try again:
    Code:
    cd ~/realtek/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
    sudo su
    make
    make install
    modprobe rtl8723e
    exit
