    rt8105e Ethernet problems

    Hello Everyone,

    I am hoping that someone can point me in the right direction. I have a lenovo IdeaPad Z570 that is running 12.10, and this is the only issue I have really had so far but it is driving me crazy.

    A bit of background:

    I am a computer technician as well as a network engineer/installer. In short, I end up configuring a lot of Ethernet devices and have to constantly plug and unplug Ethernet cables to my laptop. I can typically get though unplugging/re-plugging two or three devices before my Ethernet adapter stops responding. It seems that the only way that I can get it to respond again is to reboot. (Thankfully this is an i7 with a SSD).

    About the installation:
    -Single operating system (Ubuntu 12.10)
    -Encrypted LVM drive
    -Typically control the Ethernet connection through the Gnome3 network icon.
    -Several different "Wired" connections in the connection manager. (different configs for connecting to different equipment)
    -Ethernet works fine from live disks as well as Windows.

    Here is the results of dmesg |grep eth0
    [ 2.102314] r8169 0000:03:00.0: eth0: RTL8105e at 0xffffc90000c72000, f0:de:f1:a9:3e:e6, XID 00a00000 IRQ 41
    [ 37.684705] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
    [ 38.316314] r8169 0000:03:00.0: eth0: link down
    [ 38.316821] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
    [ 38.317075] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready



    I don't really know where to go from here, so any advice would be greatly appreciated. I am assuming this is a driver issue and that I am using some sort of default driver when I should be using a more specific one, but I am not proficient enough to get any further that that lol.


    Thanks in advance,
    Jordan

    Please show the terminal outputs of:
    Code:
    uname -a
    lspci -nnk | grep -iA2 net
    cat /etc/network/interfaces
    cat /etc/resolv.conf

    Additionally, please install the package "ethtool" and show:
    Code:
    sudo ethtool eth0

    Link detected: no
    Did you check the cable itself? Tried another port? Any messages with:

    Code:
    sudo ifup eth0

    Re: rt8105e Ethernet problems

    Hey,

    I do not currently have anything connected right now, I am currently bridging through a wireless device. Should I make it crash and give you the same output?

    Thanks,
    Jordan

    Re: rt8105e Ethernet problems

    So I have tried to replicate the issue with wireless off as well as on but of course now that I want it to crash it won't lol. I think the only way I am going to get it to is by simply using it as I normally do and wait for it to happen. I am going to try doing a mock setup scenario so that it will go through the usual motions tonight and hopefully it will find that agreeable.

    I don't know if this helps, but it seems to be related to me switching between layer 2 and layer 3 network work. For layer 2 I typically assign a static IP to the interface and carry about my work. I then usually end up needing a different static and switch to another preconfigured connection. I am unable to see any Layer 2 stuff without having some sort of IP statically configured on my computer (This is usual behaviour).

    Also, the hardware appears to be listed as " RTL8101E/RTL8102E PCI Express" yet the driver is "r8169". Should I be tracking down a specific driver instead of this one?


    Thanks again,
    Jordan

    Re: rt8105e Ethernet problems

    Hello again,

    So I managed to get it to crash and tried reloading the module. This seemed to get it going again so I carried on with finding the proper driver. I created a r8101 module, and replaced the loaded r8169. So far so good . I may need some help if this goes south though lol.

    Thank you for your help,
    Jordan

    P.S How can I mark this as resolved so that I can create a new thread later?

    Should work by editing the 1st posting
