    Intel / 13.04 / Lenovo Y580 / Wireless & Wired Connection Issue

    Greetings,

    After upgrading to 13.04, I lost network connectivity (wired and wireless). I fixed the wired issue, but now I cannot connect to my network through wifi. I have posted below the information requested in the sticky.

    Also, to give a better description of the problem: the wlan0 interface appears to be up, but when I try to connect to my network the notification just says "Connecting..." and it stays like that until it stops connecting.

    Thanks in advance.

    EDIT: The wired problem is actually not fixed. In fact, it's nigh unusable. I am able to connect to my wired network, ping 8.8.8.8 or any other site, and get online in a browser. After a few minutes however, even though I am still connected, I am unable to send/receive information (by pinging google's server or through a browser). The issue is resolved by opening up a terminal and issuing the command

    Code:
    $ sudo modprobe -r alx && sudo modprobe alx
    but that's really not a solution since it just breaks again after 10 or 15 minutes.

    I am posting this from my 12.10 partition. I've included the lspci for the ethernet, if any other information is needed I would be glad to supply it.

    Code:
    $ lspci | grep Ethernet

    Re: Intel / 13.04 / Lenovo Y580 / Wireless & Wired Connection Issue

    Bump.

    Could anybody give me some place to start at least? Would installing an earlier version of the driver help?

    Re: Intel / 13.04 / Lenovo Y580 / Wireless & Wired Connection Issue

    Have you considered that the problem lies between the router and the ISP and not between the computer and the router? Those command listings that you provide show that the machine is connected to the router both by ethernet and wireless adapter. The drivers are installed and working. The wireless adapter is detecting wireless access points..

    I have never had a problem on my machine with getting a connection to my router. So, to learn about the listings/reports I simulated a failure. Disable Wired Connections and run those commands again. Disable Wireless connections and run those commands again. Compare the reports. Notice the differences when things are broken and when they are working.

    Go into the router set up program and see if there is any indication of a breakdown at the ISP. Check the connection to the ISP. Go online to the ISP's web site to see if there are reports of the ISP being down for repairs or something like that. Check the quality of the connection to the ISP. Is the telephone wiring of good quality?

    Is there an alternative driver that can be used?

    Regards
    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    I'm about 100% sure it's not a router or ISP problem. On the same computer on a windows 8 partition and an ubuntu 12.10 partition everything works fine.

    Re: Intel / 13.04 / Lenovo Y580 / Wireless & Wired Connection Issue

    First try to deactivate the N-mode of the wifi driver (bug):
    Code:
    echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
    sudo modprobe -rfv iwlwifi
    sudo modprobe -v iwlwifi
    Second, please show

    Code:
    cat /etc/resolv.conf
    route -n
    dmesg | egrep 'alx|iwl'

    Re: Intel / 13.04 / Lenovo Y580 / Wireless & Wired Connection Issue

    praseodym, thanks for your reply.

    I tried what you said.

    The output of the commands is as follows:

    Code:
    $ echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
    options iwlwifi 11n_disable=1
    
    $ sudo modprobe -rfv iwlwifi
    FATAL: Module iwlwifi is in use.
    
    $ sudo modprobe -v iwlwifi
    $
    And the output of the second set of commands is as follows:
    Code:
    $ cat /etc/resolv.conf
    # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)

    In case it matters, my connection is WPA encrypted. I have no problems connecting to it from my 12.10 partition or my win8 partition.

    grahammechanical,

    I am fairly certain this is a driver issue. From what I've read, you shouldn't use a driver version below what your kernel version is (from the compat-wireless page:

    "compat-wireless stable releases

    Here are the list of stable releases of compat-wireless.

    NOTE: Please be aware that the releases below contain code from the given version of the Linux kernel. Therefore to add functionality, you should select a version that is later than your kernel version.").

    The versions of the driver which I use are listed here: http://wireless.kernel.org/en/users/...table_releases

    As you can see, the latest stable is for the 3.6 kernel, whereas the upgrade pushed me on to the 3.8 kernel.

    What about WPA2?
