After my latest Ubuntu distro upgrade to version 11.10, wireless connection became extremely slow. The upgrading procedure failed on configuration files update dialog and I rebooted the laptop and run apt-get upgrade... Could that be because of misconfiguration or wrong driver? Any ideas?
You might have several misconfigurations since you mentioned that the upgrading procedure failed. What I suggest is to do a clean install to be on the safe side. Do a backup of your files and just do a clean Ubuntu install. It will save you all the hassle for looking for the culprit and enjoy the 11.10 as new.
