Dear Maintainer,
Installed Debian Jessie on a shiny new Thinkpad X1 Carbon gen3 (2015) but wireless has been unusable so far.

Things I have tried:
- Add 11n_disable=1 option to iwlwifi.
- Force CRDA region on cfg80211_getdom option to JP an US
- Set region to JP/US on /etc/default/crda
- Change thousands configurations on my routers.
I have tested three wireless routers and the wifi on my machine presents the same problem. It gets disconnected every few seconds making it practically unusable.
