Public bug reported:
Hi,
are in possession of the x201 notebook with the wireless card "Intel (R)
Centrino (R) Advanced-N 6200 AGN, REV = 0x74" after upgrading to xubuntu 16.10
I observed a slowdown in wireless connection. After several attempts and
drivers checked:

and verified the /etc/modprobe.d/iwlwifi.conf configuration file:
options iwlwifi swcrypto=1 11n_disable=8 bt_coex_active=0 led_mode=1
without getting any improvement, reading on the internet I saw that the problem
could be the frequencies of the wireless card, in fact across power of the NB I

after the command of "iw reg set IT" connect regains velocity having before
upgrading to 16.10.
At this point I changed the line "REGDOMAIN = IT" in /etc/default/cdra, but on
reboot everything went back to the German frequencies DE. To solve I added
temporarily in /etc/rc.local "iw reg set IT".
Please could you fix it? Thank you
