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.

The AP uses WPA, but the driver has been told that WPA is disabled. Are
you using wpa_supplicant (or NetworkManager, or something else?) to
control the WiFi, and if so what version is it?

Thanks for the logs. I compared your network manager log with the one on my setup. Both are same. Basically network manager log doesn't show security info (WPA/WPA2, encryption mode etc). So we can't rely on that.
I checked your kernel log shared in previous email. It's incomplete. It didn't include information when connection was actually attempted. Probably you can run "dmesg -c >> dmesg.log" in loop with some delay to capture complete info. Otherwise sharing "/var/log/messages" is also an option.
I have created a driver debug patch(attached). Could you please apply it and share complete dmesg log?
Btw, do you see the problem if AP is configured in WPA2 security mode?
Regards,
Amitkumar

NetworkManager leaves the 'protos' field empty, which allows the
supplicant to choose the correct WPA/WPA2 mode depending on driver
support. What you see in the NM logs is exactly what gets pushed to the
supplicant in the network block. So if you don't see "proto" or
"pairwise" or "group" in the NM logs, then it doesn't get pushed to the
supplicant, and the supplicant uses its default behavior, which should
be:
proto=WPA RSN
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40

Here are the relevant entries from the syslog file:
I included the failed attempt to connect to the WPA protected network
named "southcentral" and the successful one to a non protected one named
"FreeWifi".

Thanks a lot for making my laptop usable again. I'll be happy to test
the fix when it's ready.

I applied your patch. Here are the dmesg logs when logging to a WPA
network with authentification (dmesg-WPA.log, ssid southcentral) and a
network without authentification (dmesg-noWPA.log, ssid FreeWifi).
Let me know if you need anything else.

Good catch, I changed my access point to WPA2 and now I can connect to
it ! I attached the corresponding dmesg logs (dmesg-WPA2.log, ssid southcentral).

Could you check if attached patch fixes your connection problem with WPA AP?

It seems ok so far. I have set my home router back from WPA2 to WPA and
I can successfully connect. I'll let you know if I experience some
problems with it.
Thanks for your help.

Julien.
