One more question : does dmesg tell you something is wrong with
bcm43xx when you try to configure wireless?

  I requested help for a wireless problem a few days back.  I tried loading the windows driver and the ndiswrapper for the internal modem and got the message error that it was the incorrect driver....  I also have a USB modem working perfectly with Kubuntu 6.06, that will not operate under Ubuntu 6.10.  Is there a known issue and will it be fixed in full release version?  I much prefer Ubuntu and would prefer to sort wireless issue
