I found what might be causing the problem. My system recently upgraded kernel
to 3.15.4-gnu (linux-libre from jxself repository). Well I found out that if
I load the 3.14.6-gnu there is no problem, I can connect to any wifi network,
while if I load any 3.15 version, it won't work with any password-protected
networks.
Just in case anyone ask me why I'm using that linux-libre version, it's
because my laptop usb port wasn't supported by the default version 3.2 (I
think it was you, Chris, who suggested that solution to me by email when I
bought the USB adapter).
If this is the issue, what should I do, wait for newer versions of the
kernel? Will it possibly be fixed in the future?
By the way, lembas, I think havlet is not proprietary since I found it in
trisquel's repositories. If it actually is proprietary, who should I contact
to remove it?
Thanks a lot.
