    Weird WLAN Card Behaviour : Smashback

    So , Hi ... again ...

    I had problems with my WLAN Card Firmware and DMA but these problems are fixed . Now , since yesterday , I need to shut my WLAN Card down at every ... I say , around 10th minute ( Time not static ) . And if I do
    Code:
    dmesg | wlan
    ( my WLAN is wlan0 ) , I get ( just at the end )
    Code:

    repeated over and over again . It is since yesterday , and NO , I AM NOT IN EGYPT ! But I am in Germany .
    Some weeks ago , I changed from UBUNTU ( gnome , gdm ) to KUBUNTU ( kde , kdm ) and do not had such problems , just problems with sound where I need to link PulseAudio and Phonon to ALSA ( PA and P still need SoundCard Settings ) and ALSA to my right sound card . But this is another story and not such important , I think it is even an Feature ( System Sounds over Speakers ( PA ) and anything other over Headphones ( P , A ) ) .

    BTT ( Back To Topic ) : Can someone help me with my Timeouts ? Is it the fault of my mac adress , ip adress or router because of setting " mac adress filtering " to on ? I added my Laptop on the list .

    And I noticed that it happens mostly while my screencaver is used ( I use xscreensaver and had never problems and did not changed the screensaver ) .

    And I said Smashback ... If something happens , it is not comming alone ...

    Everytime if I download something or use Skype or something , my laptop lags horribly . Why ?



    It would help me much if you answer to problem 1 ( timeout ) and 2 ( lag ) .

    Thanks for Help

    PS : If you want to know : I have an Broadcom43 with ucode5-series .fw-files ( hard to get ) .

    Edit : Just uploading this tread is making my WLAN stop ...

    Okaaaayyy ... UFW is the Firewall and GUFW has been configured properly ... But is my Firewall blocking my WLAN ? This would be unlogical . And after loosing connection to internet , disabling UFW and then connecting , still no internet until I restart my wlan card ...


    So : What is blocking WLAN ? Virus ? Firewall ? And is UFW short for Ubuntu FireWall ?

    Ok , I found it : My BitTorrent Manager , Transmission .

    Theory ( I do a lot of them so I can check if I think the right thing ) :

    Transmission has blocked ports on my Firewall . Transmission wants to ignore it , gets focus and timeouts my firewall . With it it stops my Internet Connection .

    Is it right what I think ? And which Ports do need to be open ?

    Just got worse : Every big file ( over 200 MB ) being downloaded is being catched by my Firewall and timing my WLAN CONNECTION out . Any solution ?
