I saw several similar threads, but none really does it...
I have 12.04 precise x64 installed and things worked great for some 10 days. Then it all stopped - I wasn't able to connect any more.
Even more, things were so scre*ed up that it were showing other network's name while connecting :(
I have an Asus K53SM-SX054. Here's the text from dmesg related to my card:
Basically, it's Intel Centrino Wireless-N 1030.
Not sure if it's important, I had Gnome with unity and then moved to KDE.
Any ideas what to do? I'm on the verge of reinstalling things, but I already set plenty of things and have some things that I'd need to back up... and I'm rather lazy to go on with it :)
EDIT: My wlan network is hidden. Not sure if this should have any influence.
