Intel Centrino Advanced-N 6205 Wifi Frequently Disconnects from Network

[Martin Dluhos]

version: Linux Mint Olivia 15
kernel: 3.8.0-33-generic
Network Card: Intel Centrino Advanced-N 6205 [Taylor Peak]
driver: iwlwifi

It happens to me a few times a day that my network connection drops. I haven't been able to identify a pattern yet that would give a hint as to why this happens. Sometimes it happens when I am streaming music, while at other times when I am only web browsing or even away from my computer (with my browser open). There are other networks which are in range, but Network Manager never tries to connect to them, so I don't think they are part of the problem. The disconnect might have something to do with cfg80211 updating the world regulatory domain since that is reported in syslog right after this line:

wpa_supplicant[1814]: wlan0: CTRL-EVENT-DISCONNECTED bssid=00:02:cf:ca:44:f6 reason=4

I am including the relevant part of syslog for reference.
