    2.6.32.26-generic killed my network

    There was a recent kernel update for Lucid, 2.6.32.26-generic that completely killed my networking. It was working perfect under .25-generic. This is a broadcom wireless with Broadcom STA proprietary driver and atheros wired. The proprietary driver is inactivated and impossible to activate.
    Code:
     *-network UNCLAIMED     
           description: Ethernet controller
           product: AR8151 v1.0 Gigabit Ethernet
           vendor: Atheros Communications
           physical id: 0
           bus info: pci@0000:01:00.0
           version: c0
           width: 64 bits
           clock: 33MHz
           capabilities: bus_master cap_list
           configuration: latency=0

      *-network

           physical id: 0
           bus info: pci@0000:02:00.0
           logical name: eth0
           version: 01
           serial: c4:46:19:51:bc:fb
           width: 64 bits
           clock: 33MHz
           capabilities: bus_master cap_list ethernet physical wireless
           configuration: broadcast=yes driver=wl0 driverversion=5.60.48.36 ip=192.168.0.15 latency=0 multicast=yes wireless=IEEE 802.11
           resources: irq:17 memory:d2400000-d2403fff
    Neither wired nor wireless works after this update. wl is not in "lsmod" list as it is in .25 kernel and it's not possible to modprobe it either. What do I do? Please help.

    It looks like it's working to me:
    configuration: broadcast=yes driver=wl0 driverversion=5.60.48.36 ip=192.168.0.15 latency=0 multicast=yes wireless=IEEE 802.11
    resources: irq:17 memory:d2400000-d2403fff
    Can you ping the router?

    ping -c3 192.168.0.1

    Let's see if there are any interesting messages about this. Please post:
    Code:
    dmesg | grep -e wl -e eth
    Thanks.

    dmesg | grep -e wl -e eth
    Code:
    [   12.926282] wl: disagrees about version of symbol module_layout
    Sorry about the above ping message, I was in the wrong kernel. I have to reboot every time so I got confused. This is the message from trying to ping my router:

    connect: Network is unreachable

    Re: 2.6.32.26-generic killed my network

    Ok, now it's working. This is what I did:

    Uninstall everything 2.6.32-26 with synaptics
    rm -r /lib/modules/2.6.32-26*
    reinstall linux-headers-2.6.32-26 linux-headers-2.6.32-26-generic linux-image-2.6.32-26-generic

    Alive and kicking again. Probably something went wrong during the update

    Thanks for your help.
