I can't connect anymore to my home wifi since upgrading my machine from
Ubuntu 15.04 to Ubuntuy 15.10. I was previously running kernel 4.3.0-rc2
from kernel.org without any problem. After the upgrade, and with the
same kernel, I couldn't connect anymore. I built 4.3.0-rc7, and the
problem remains. However, I can connect to the wifi access point from my
Android phone.

Here are the relevant lines from syslog. Let me know if you need more
information.

The machine is a Microsoft Surface Pro. I've been having a lot of
problems getting the wifi to work but never this particular one, and
they were all fixed in 4.3.0-rc2.

You could check it by disabling the NetworkManager and connect using
wpa_supplicant manually. Sometimes NetworkManager does some problem
which is solved by disabling the NetworkManager.
