    Re: No wireless after 12.10 installation

    So my connection is better, but it still drops out once in a while. I am still not sure why opening Transmission kicks it back on, but that is my goto rite now.

    Cool Re: No wireless after 12.10 installation

    FYI: It seems the newest kernel update to 3.5.0-24 killed wifi on Toshiba Satellite C850D-121. 3.5.0-23 still works OK.

    Any chance you'd like to troubleshoot?

    Sure, but you would have to guide me 3.5.0-25 has the same problem btw.
    Sorry for the late reply. I had forgotten to enable notifications.

    First, tell us about your wireless card details. Open a terminal and run and post:
    Code:
    lspci -nn | grep 0280

    Currently using 3.5.0-23 to be able to be on the net

    Re: No wireless after 12.10 installation

    And the following is running 3.5.0-25
    I don't see much wrong here. What I don't see that I wish I was seeing is the result of clicking on one of these networks, asking for a connection and it refusing. What happens when you try to connect?
    Code:
    keyfile: parsing Felix-II ... 
    keyfile:     read connection 'Felix-II'
    keyfile: parsing SPX-Guest ... 
    keyfile:     read connection 'SPX-Guest'
    keyfile: parsing Tanghus ... 
    keyfile:     read connection 'Tanghus'
    keyfile: parsing NETGEAR ... 
    keyfile:     read connection 'NETGEAR'
    keyfile: parsing Nokia_950_tanghus ... 
    keyfile:     read connection 'Nokia_950_tanghus'
    Please be a little more specific than 'newest kernel update to 3.5.0-24 killed wifi.'

    It's quite long, so I've made a pastebin http://pastebin.com/qgHUDcsa

    KDEs network manager pops up asking for password two time during this log session, but connection still fails. The only difference is that I select a different kernel version at grub menu.

    Yeah, sorry about that. I was on my way out, and just wanted to warn any that a kernel update could break wifi.

    Re: No wireless after 12.10 installation

    I googled the message:
    wlan0: capabilities/regulatory prevented using AP HT/VHT configuration, downgraded
    ...and I found this: http://www.spinics.net/lists/linux-w...msg103577.html
    Yeah, it's obvious that this would happen for drivers not supporting
    TDLS -- will send a patch.
    Notice the date is just a few days ago; Sun, 2013-02-17 at 00:31.

    You could just use the previous kernel and wait for a fix or you could try linux-backports-modules-cw. Frankly, for a flaw that was discovered so recently, I doubt backports would have been updated by now.

    You might also try a driver parameter:
    Code:
    sudo modprobe -r rtl8723ae
    sudo modprobe rtl8723ae swenc=1
    If it helps, we can write a quick file to make it persistent.

    Ah, great that it is already known of.

    The driver parameter didn't work, so I'll just keep using .23 and download backports once in a while to see what happens

    Thanks for your help - I wouldn't know where to look.
