    Question Re: problem realtek 8723 driver

    On Ubuntu 12.04 I've managed to make and install the RTL8723e drivers in 8723AE_8723AU_Linux_support_0419.tar.gz and rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012.tar.gz.

    However the wireless networking still fails to work.
    Boot.log contains the following related entries:

    Why both? You should only need the second one.

    Please try again:
    Code:
    cd Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012  <--or wherever you extracted the files
    sudo su
    make clean
    make
    make install
    exit
    Any errors?

    Re: problem realtek 8723 driver

    Thanks for the quick response, Chili555.

    I did as suggested but still get the very same error.
    The error does not present in /var/log/boot.log, but in /var/log/dmesg.

    Re: problem realtek 8723 driver

    Do you have linux-backports-modules-cw installed? On my test mule, I get the same error with cw installed but it loads without drama after I removed it. Please remove it and reboot; then reload rtl8723e and let me have your report tomorrow.

    Don't ask me how I know this. I need to get a real life!

    Thanks again for the advice chili555.

    Unfortunately I don't have linux-backports-modules-cw installed.

    Re: problem realtek 8723 driver

    Hi chili555

    I've got a clean 12.04 install with the network driver installed and working, but wireless realtek 8723e installed but not working.

    Additional Drivers shows Qualcomm Atheros Gigabit Ethernet Driver activated and currently in use, but Realtek 8723e 802.11n PCI wireless activated but not currently in use.

    Here is the requested output:

    I don't think the driver was written for 64-bit. You could email Realtek:
    description: Realtek 8723E 802.11n PCI wireless
    license: GPL
    author: Realtek WlanFAE <wlanfae@realtek.com>
    author: lizhaoming <chaoming_li@realsil.com.cn>
    Or you could try a 32-bit live CD and see if it compiles and loads without error, as I am confident it will.

    If you have more than 2 Gb of RAM, as most of us do, it will be recognized with a 32-bit pae kernel. From my machine:

    Re: problem realtek 8723 driver

    Thanks chili555,

    I've taken your advice and emailed the authors of the driver package the relevant information.

    I'll test 32bit Ubuntu 12.04 LTS later today when I get a chance and get back to you.

    Much appreciated,
    Robin
