    Exclamation Upgrade to 8.04 breaks wireless!!!

    After system restart following an internet upgrade from dapper (6.06) to Hardy (8.04), wireless network connection to internet no longer existed. Here are some console logs that may help (kernel version is 2.6.24):

    myhome@mycomputer:~$ sudo ifdown eth0
    RTNETLINK answers: No such process
    There is already a pid file /var/run/dhclient.eth0.pid with pid 8355

    myhome@mycomputer:~$ sudo lspci | grep -i Network

    iwlist scan reports “no scan results” for both wifi0 and eth0


    after using lspci -v | less in the console, the results for the network controller where thus:
    05:06.0 Network controller: Standard Microsystems Corp [SMC] SMC2602W EZConnect / Addtron AWA-100 / Eumitcom PCI WL11000 (rev 02)

    I/O ports at a400 [size=64]

    again, here are more results of tests:
    myhome@mycomputer:~$ sudo lshw -C network

    configuration: broadcast=yes driver=hostap firmware=0.7.6 latency=0 module=hostap_plx multicast=yes wireless=IEEE 802.11-DS


    When i click on the configure button inside the network monitor tool on my desktop panel, i receive this error message when it is set to eth0:

    The interface does not exist
    Check that it is correctly typed and that it is correctly supported by your system.

    As i ran these tests, the wireless network monitor reported eth0 as disconnected.

    Please feel free to instruct me as to how to gather more relevant information.

    Isn't eth0 your wired ethernet interface? Your wireless appears to be wifi0. Can you click and configure wifi0? Also scan needs to be run as sudo.

    After another reboot, an interesting thing happened. eth0 was recorded as sending in the screen of the network monitor applet, but not receiving. After i typed in wifi0 into the field of the applet, it showed me that wifi0 was receiving but not sending. Is this important?

    I ran sudo iwlist scan, but again it returned no results for eth0 and wifi0.
    I cannot configure wifi0.

    Let's take a look at the terminal command ifconfig and lspci. Thanks.
