In Ubuntu 14.04.0, I pressed the 'Suspend' button by accident and when my computer woke up it couldn't connect to the internet. What I noticed is that it was asking for a WEP key for the network it already knows, rather than WPA. Regardless, it shouldn't be asking for such info because it already knows the key. I restarted my computer and the issue still persisted.
When I next suspended my computer wouldn't turn on for a minute or two, and when at least it turned on it went straight to grub's boot screen. This implies that the suspend function infact shut down my computer without question. After the third suspend, my internet was restored. It's weird, but there are serious flaws with the suspend button.. especially due to the fact Ubuntu doesn't warn you before you suspend! Avoid the suspend button!!!
Vormeph,
We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.
Presumably this problem was a one time occurrence and/or is no longer an issue? Can this bug report now be closed?
If we do not hear from you the bug report will close itself in approximately 60 days time.
Thank you for helping make Ubuntu better.
