It's an even more general issue I think. The problem is, whenever anything goes wrong in the connection process, nm-applet asks the user for a password. It makes no difference, whether the wifi went down completely, the dhcp server didn't respond or anything else happened. Most of the times, it totally makes no sense, to ask the user for a new password. A clear error message with the reason for the connection problem, or the possibility to provide manual network configuration e.g. if dhcp fails, would be much better.
I'm travelling a lot and use new wifis nearly every day. Lots of them are badly maintained hotel or restaurant wifis. Given correct credentials, most connection problems are cause by bad connectivity, someone switching of the wifi unexpectedly, or by problems with the DHCP server on the router. While of course nothing helps against the first, just setting the IP address manually to something like 192.168.1.... sometimes does the job. So if there would be some proper exception handling for the connection process, a menu to enter configuration settings manually could be provided, or some configurations could be tried out automatically, even if DHCP setup fails. And for bad connectivity or network shutdowns, this could be handled by retries with increased timeout and clear error messages, finally switching to other networks if available, without disturbing the user with a password dialogue. For the inexperienced user this is just totally misleading and keeps him retrying, while there is no hope for cure for the connection at all. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1010745 Title: network-manager forgets my password when an error occurs Status in “network-manager-applet” package in Ubuntu: Confirmed Bug description: My home wifi is slightly flaky, and stops working when there's a lightning storm or excessive traffic. It comes back after a while. But in the meantime, network-manager can still identify it but can no longer connect. What happens: For some reason network-manager decides this means the password must have changed and prompts me for a new one, forgetting the old. This does not work, of course, and it means that network- manager can't reconnect automatically when the wifi starts working again; in fact it can't even tell me whether it is working again, and it forces me to dig up the password I use. What should happen: The dialog box that comes up contains an error message. It offers "Retry", "Change Password", and "Cancel". Ideally the error message would contain some sort of information about what went wrong, perhaps including a "more information" section that lets me see detailed technical information. I realize getting this extra information can be a problem, since the network system is running as root, but at least it would be nice if network-manager did not assume that the network had changed its password, and especially if it didn't forget my old password.
