Thinkpad T410 WiFi NIC on Linux

The WiFi connection of the T410 has been a bit spotty, forever.
At first I thought it was a kernel related problem, but even the latest and shiniest gave the same errors, so a bit of Google turned out this:

unreliability with Centrino Ultimate-N 6300 wireless connection, 802.11n

Suggested that issuing this:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi bt_coex_active=0
sudo emacs /etc/modprobe.d/iwlwifi.conf

options iwlwifi bt_coex_active=0

And then rebooting.
Things seem to be really, really improve after this.
