Thread: Realtek RTL8191SE and no wifi access!

  1. #1

    Default Realtek RTL8191SE and no wifi access!

    Hello, please, could anybody help me with my wifi on my notebook ? ( Toshiba Satellite ) So I have used google and read a few topics here at this forum. ( especially this Getting Your Wireless to Work was very interesting for me ) But it is useless for me, because I am newborn in GNU/Linux. I use openSUSE 11.3 with KDE. I have read, that you need some informations about my hw. I hope these are

    on website of realtek Realtek

    but I dont konw what should I have to download

    dmesg | grep firmware

    [ 2.801713] platform radeon_cp.0: firmware: requesting radeon/RV710_pfp.bin
    [ 2.803156] platform radeon_cp.0: firmware: requesting radeon/RV710_me.bin
    [ 2.804667] platform radeon_cp.0: firmware: requesting radeon/R700_rlc.bin

    You should also inspect the boot log for other information regarding your device. In particular look for messages that your radio kill switch has been activated. A number of people have felt rather silly when they posted that their wireless didn't work, only to be told to "turn it on".
    I don't uderstand...

    what should I look for at this log?

    Thank very much for your advice and for your time for me.

    The driver for the USB device with ID 10ec:8172 that is in kernel 2.6.34
    (openSUSE 11.3) is broken for most devices. I have a newer driver that I got
    privately from Realtek that works reliably and it will be pushed to the kernel
    soon (I hope). The holdup is that Realtek's lawyers have not signed off on the
    copyright in my new version. Until they do, there is little I can do.

    2 vnicolau: no, I didn't read this topic, it seems very simply, but I have never compile anything so I have use google "how to". I am very skeptic about my ability to do this procedure.

    2 lwfinger:

    What does it mean for me ( and other users with this realtek )?

    When the lawyers sign it, it can be install by Yast2? How can I know, that it already is in kernel?

    And now...? Should I download RTL8191SE-VA2 and try to use it? But I have RTL8191SEvB?

    2 lwfinger: I have found your post here New IMB Lenovo L512 >I downloaded the drivers and Need to install them. ... so I suppose it is your next advice?

    The 10ec:8172 device is not
    supported by any drivers in even the latest kernel, thus you will need to build
    the driver. To do this, you need to have the kernel headers installed. To get
    these, issue the command

    Code:

    sudo zypper install kernel-headers

    With these available, you should be able to change directory to the one that
    contains the Reaktek source, and enter "make". There is good news - I downloaded
    the driver from the Realtek site and compiled it with no changes. There were two
    warnings that can be ignored. Once the build finishes, you should copy the
    firmware as described in the instructions you posted, and load the new driver
    with the command

    Code:

    sudo /sbin/insmod HAL/rtl8192/r8192se_pci.ko

    You should now be able to bring the wireless device up with NetworkManager. If
    it works this way, then you can "permanently" install it with

    Code:

    sudo make install

    The installation is not really permanent as the driver must be rebuilt and
    reinstalled each time there is a kernel update. The firmware will remain. You
    only need to do that step with a new installation.

    As you see, these instructions are a lot simpler than the list you posted
    earlier. Ignore those except for the step that says to copy the firmware.
    It may be better to wait for "your built in kernel". Until NDISWrapper or to buy an external usb wifi adapter

    When my new driver is ready, it will be submitted to the mainline kernel tree
    for inclusion in the staging directory. If all goes well, it might be in kernel
    2.6.37, which might be used in openSUSE 11.4, but I expect the driver in 12.0.
    The only way to get it into 11.3 would be to use the kernel-of-the-day.

    Kernel hacking is not dangerous. If you get the code wrong, it might not build.
    If it builds, it might fail on boot. In any case, I always keep a known good
    kernel in order to recover. My GRUB menu might have anywhere between 5 and 12
    kernels listed, and only one will be "failsafe". At the moment, I have 5 and
    every entry is for openSUSE 11.3.

    Have you tried entering "acpi = noirq" in your "boot options" section at boot time. That's what worked for me.

    No, I didnť try it. I am only normal user of pc, so I have used google what acpi is! I have read many posts at different forums ( not only for opensuse ), where are many advices how to with realtek... but to my mind is the most important this

    I used
    Code:
    sudo zypper install kernel-headers
    make
    sudo cp -rf firmware/RTL8192SE /lib/firmware/2.6.34-12-desktop
    sudo /sbin/insmod HAL/rtl8192/r8192se_pci.ko
    sudo make install
    wifi worked, but until next reboot of my pc

    ndiswrapper with kndiswrapper doesnť work for me... at the last step by using GUI ( configuration wifi access ) there is suddenly no window....

    I believe, that linux power advanced user ( like lwfinger ) is able to resolve this hw problem. But not me, because my ability with pc are very low ( not only with linux,windows too ). This is laptop of my all family and we want to use it for our work and entertainment... not for father's googling and trying to do something. I have no time for resolving this issue with uncertain result. I will not change my distro, because the kernel is the same at all GNU/Linux distros and it si common mistake of beginners to change one if there exists problem. I will use GNU/Linux, I will use openSUSE, because I like it and is better for safety of my family. So I will use some external usb device for accessing internet ( no realtek driver ) and I will looking forward openSUSE 11.4 with lwfinger's modul in kernel for my realtek.

    thank you very much for everybody for your advices

    If it worked after the insmod, but failed after the next reboot, then the "sudo
    make install" did not work. The only thing I see is that a "sudo /sbin/depmod
    -a" should have followed the install step.

    After you reboot, check the output of dmesg for any messages regarding the 8192.
