Network isdn wlan problem

[Henk Altena]

I have a problem with dialing out with a Fritz! PCI isdn card.
  Totally random the device refuses to activate. I can not
  reproduce the problem.
  The card is installed in a totally updated FC7 x86_64 system.
  It is NOT a hardware problem because under Fedora6 everything
  works fine. As described below in the logfile I am afraid I
  caused the problem myself.... The question is how do I get rid of it ?
  I deactivated NetworkManager & Co. Reinstalled the latest kernel
  with --force --replacefiles.
  How can I force FC7 to 'forget' anything about wlan1 so how to
  start a totally fresh Network setup ?

  So far so good:
  THERE IS NO MORE A 'WLAN1'. Some weeks ago I tried to install a wlan card,
  a Conceptronic usb with Ralink driver. I could not get it working with
  the default drivers rt73usb from Fedora7. I tried it also with
  'ndiswrapper' with no result. Now it looks like I caused the problem..

  Because of an error message in Gnome Network Device Control (where
  I activate ippp0) I deactivated the ippp0 device. I have to activate and
  deactivate the device  several times untill it activates
  correctly. The error message in Gnome: "the device ippp0 is currently
  not available".
