    After Updates, no WiFi ?

    I did all the updates, I believe some were kernel updates. After reboot I have no WiFi. I was using madwifi and under Hardware drivers there is nothing listed now? How do I get the wifi back?

    Let get some log output!

    in the terminal type:

    Code:
    sudo tail -f /var/log/messages
    unplug and replug the card and post what you see in the log.

    Code:
    pccard: card ejected from slot 0
    pccard: CardBus card inserted into slot 0

    I'm in the same boat as you with my wife's laptop. If I find the solution for this new kernel I will post it. In the mean time, using the old kernel continues to work

    I have to admit that -- does not help much. Ok. What's the card? Just post the line from the lspci output. We can tackle it from another angle.

    do a:


    Code:
    lsmod |grep ath9k
    If it does not give you any output do:

    Code:
    modprobe ath9k
    see if anything shows up in /var/log/debug /var/log/syslog /var/log/messages

    you can also just boot into the previous kernel.

    Code:
    lsmod |grep ath9k
    generated no output
    Code:
    modprobe ath9k
    WARNING: /etc/modprobe.d/blacklist-framebuffer line 26: ignoring bad line starting with 'vesafb'
    FATAL: Module ath9k not found.
    I have yet to check the log files you mentioned.

    Not sure what version you are running, but this happened to me too. I updated last night and my wifi went down. I think it is fixed already, but I am at work and haven't been able to update again. Check this thread out....

    I had the same issue with my laptop. After I would update the kernel I would have to reload my drivers. I wrote this guide for my laptop. But I know that works with other version of the card(ARXXXX)

    Hope this helps.
