Thank you for your report please try the following. open a terminal and type the following.
sudo cp /etc/network/interfaces /etc/network/interfaces.bak now do the following. sudo gedit /etc/network/interface scroll down the list until you find your wireless connection and delete the two lines. Save the file, then reboot your machine. If that fails you can reset to the default with the following. sudo rm /etc/network/interfaces sudo mv /etc/network/interfaces.bak /etc/network/interfaces If this solves your problem please report back many thanks. ** Changed in: network-manager (Ubuntu) Assignee: (unassigned) => davmor2 -- network-manager in feisty is broken https://launchpad.net/bugs/82715 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
