wlan0: disassociating by local choice (reason=3)



Dear all,

Every time I try to connect to internet via wireless, I get the message on the title.   I want to update but can't I have to switch to wired connection to actually get the updates.  Since I do not know against which component to file a bug against, I want to ask for advice.  I saw the following running a dmesg:

Should I file against NetworkManager and let the maintainers of that package figure it out?

I am running wireless on another laptop and I have not encountered this problem.  Thanks in advance for advice/suggestions.  

Regards,

Antonio
