    Default Wireless Adapter Installation: Realtek RTL8188CE on a Thinkpad

    Hello all. I just installed openSUSE 11.4, kernel 2.6.37.1-1.2-desktop. I don't know how to properly register my wireless card.

    lspci returns: Realtek RTL8188CE

    lspci -n returns: 10EC:8176

    lspci -v returns:

    iwconfig returns:
    lo no wireless extensions.
    eth0 no wireless extensions.


    According to the HCL here: HCL:Network (Wireless) - openSUSE , my adapter should work "out of the box" with "rtl9182ce from compat-wireless."

    I located this package in Software Manager and installed rtl8192ce and rtl8192ce-firmware. There are some "rtl8192ce-kmp-*" packages here, but I haven't installed any of them. When I begin to, I'm told that I need to downgrade the kernel to install it.

    I then attempted to configure the card manually in Network Settings. This resulted in a controller listed in the Overview tab with no MAC address or anything connected to it. It didn't seem to be connected to the actual PCI device.

    Here are my results of diagnostics recommended in the "Getting Your Wireless to Work" thread:

    Yast -> Hardware Information: Under "Network Card" is the listing for Realtek Network controller. There is no "Kernel Driver" line. It is listed as a PCI device, though.

    The boot log only mentions firmware with references to the touchpad and display adapter.

    iwlist scan says the lo and eth0 interfaces don't support scanning. I stopped trying to do the network diagnostics after this.

    Have any ideas for me to try? Thanks!

    Until you install the rtl8192ce-kmp-* package for your kernel, YOU HAVE NO
    DRIVER. Everything you post is consistent with that. AFAIK, there is such a
    package for 2.6.37.1-1.2-desktop. At least on my system, the
    compat-wireless-kmp-desktop package is for 2.6.37.1_1.2.

    The specific message I get is "rtl8192ce-kmp-desktop-0005.1116.2010_2.6.31.14_0.8-1.4.i586 requires ksym(desktop:__stack_chk_fail) = f0fdf6cb, but this requirement cannot be provided"

    Then the option that involves installing it says "downgrade of kernel-desktop-2.6.37.1-1.2.2.i586 to kernel-desktop-2.6.31.14-0.8.l.i586"

    Is there a newer version of rtl8192ce than the one I'm seeing here? Would I check or repository, or should I try to install the 2.6.37_ one from stable - Linux Wireless ?

    That is an 11.3 requirement. I think you have the wrong repo installed. Please
    post the output from 'zypper lr'. When posting, put that output inside "code"
    tags to preserve the formatting."

    Compat-wireless has the same version of rtl8192ce that I do. There is nothing newer.

    First of all, get rid of that 11.2 update repo.

    It doesn't say so here, but that driver.wireless repo has to be for 11.3. Using
    YaST => Software Repositories, please fix that.

    A new compat-wireless is generated daily. I don't know how frequently it is
    updated on openSUSE, but the one I have was built on March 28, 2011.

    I fixed my repository list like you said. The rtl8192ce-kmp-desktop package requires a kernel(desktop:net_sched). The rtl8192ce-kmp-default package didn't require this, however. So I installed it and then switched to kernel-default instead of kernel-desktop.

    This has partially worked. Now I can see and configure my wireless card in the wireless manager:

    Code:
    ~> iwconfig
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wlan0     IEEE 802.11bgn  ESSID:off/any  
              Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
              Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
              Encryption key:off
              Power Management:off
    Maybe I configured it incorrectly, but I didn't try setting my home network right away because I need to be able to scan when I go to school. However, scanning goes like this:

    Code:
    ~> iwlist wlan0 scan
    wlan0     Interface doesn't support scanning : Network is down
    Software Manager also has updated drivers for rtl8192-kmp-default, but it says that they depend on a newer version of kernel(default:net_sched). I thought this might resupporolve the interface error, but haven't been able to install it.

    A search RPM Search OpenSuSE kernel-default-base-2.6.34-12.3.i586.rpm looks like kernel(default:net_sched) is in kernel-default-base. I have kernel-default-devel 2.6.37 and kernel-default-base 2.6.34, but upgrading to kernel-default-base 2.6.37 requires that same package: kernel(default:net_sched).

    This usually means the rfkill switch is off.

    My laptop uses a function hotkey for the rfkill switch. I set BIOS to default it 'on' during boot. The other function hotkeys, like volume control, are working and I can see them adjust this GNOME volume popup, so they're working.
    Is there some way to verify that the kill switch works? Toggling it right now doesn't have any noticeable effect, but it should be on.

    Code:
    /usr/sbin/rfkill list
    will in my amateurish thoughts give you more information - like on my old lappy:
    Code:
    0: phy0: Wireless LAN
    	Soft blocked: no
    	Hard blocked: no
    If rfkill is not installed jet - install that software package first.
