wifi disconnection / deauthenticating from ... by local choice (reason=3)
 

Anyone knows where the following problem comes from?

In the last hours, I've had a wifi disconnection twice, while I had
never had such a problem before. Concerning the second connection and
disconnection (at 01:48), the kernel and dhclient logs contain:

Not yet, but I don't use the wifi very often.

I use wicd, but its logs at this time are:

2011/08/19 01:48:46 :: attempting to set hostname with dhclient
2011/08/19 01:48:46 :: using dhcpcd or another supported client may work better
2011/08/19 01:48:47 :: attempting to set hostname with dhclient
2011/08/19 01:48:47 :: using dhcpcd or another supported client may work better

then when I reconnected, as usual:

2011/08/19 01:49:20 :: Connecting to wireless network vinc17
2011/08/19 01:49:20 :: attempting to set hostname with dhclient

[...]

So, it seems that wicd wasn't responsible of the reason=3, unless
it didn't log what it did.

but in debug mode, wicd also writes:

2011/08/20 02:39:40 :: Forced disconnect on

So, it is the cause of the disconnection. I've reported the bug:
