Some observations that may help others:

1. About a week ago it was really difficult for me to connect to my wifi
network. The error was the infamous

"wlan0: deauthenticating from xx:xx:xx:xx:xx:xx by local choice
(reason=3)".

It turns out that by updating "managed=true" in
/etc/NetworkManager/NetworkManager.conf , I no longer see this error
message. (thanks to
http://ubuntuforums.org/showthread.php?t=2070648&page=2 ). Instead I
sometimes see

"wlan0: authentication with xx:xx:xx:xx:xx:xx timed out".

This error message doesn't appear as often, so now I have a much better
chance of establishing the initial connection (typically only 1-4
trials).

2. The dreadful "local choice (reason=3)" error will come back if I
remove and then insert the r8192ee module as suggested in #71. My
solution is to either reboot, or kill the wpa_supplicant and
NetworkManager processes.

3. I have reached a state where I can reliably connect to the wifi
network after a few trials, and the driver feels usable (albeit the
package drop rate sometimes seems higher, especial). I'm content with
the current driver in #66, and I really appreciate Larry Finger's
effort.

On the other hand, I think the current driver is a bit unfriendly to new
(T440s and other laptops) users, because the initial connection attempts
require repeatedly and manually disabling and re-enabling Wi-Fi in the
Network Manager applet. I look forward to seeing reliable initial
connection that is automatic.
