I'm using Sid/amd64 on my notebook and I have a Android smartphone. My
notebook has no problems to associate to every WiFI access point I
tested so far, including mobile phones hotspots, except the hotspot of
my own smartphone.
On the other hand, another notebook I have (booted with Systemrescuecd)
has no problems to associate to my smartphone hotspot, and the same is
true for other notebooks of a few friends I asked to.
I'm using XFCE, though I suspect that doesn't make any difference,
because Systemrescuecd also uses XFCE.
When I try to associate my notebook to my smartphone hotspot, the
password dialog simply pops up again, but I'm sure I enter the correct
password.
I've already tried changing the password, changing the SSID, removing
the network from NetworkManager and rebooting everything: no dice.
Can you please help me spot the problem?
