I have the same symptom, but with Broadcom wireless card and fresh install of Kubuntu. Tried also Mint 17, same behavior.

But if I leave the computer unattended for some time, ie no network traffic, the connection drops and the system asks me the password to connect, but the password is correctly configured so that if I cancel the dialog and click on the link at nm-aplet(tray icon) it is reconnected without the need to reenter the password. It seems to me that has to do with network-manager because sometimes there is a notification from the system that informs timeout of autentication from wpa-suplicant. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1276238 Title: Wifi Connection Dropping/Need to reconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1276238/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
