Intel Advanced-N 6205 (ThinkPad T520) - Microcode SW error detected

I have got problems after I connect to my wireless network (WPA2 Personal/TKIP). Very often even if my wlan0 is up for example ping doesn't work. Sometimes I have got connection for a short while. After I typed: pacman -Syu, I got: Microcode SW error detected. Logs:

Between same errors:

I read about related problems and decided to turn off 11n feature via: options iwlwifi 11n_disable=1 in /etc/modprobe.d/iwlwifi.conf. It seems to work now but I don't have enough time to test it better.
I'm using 3.4.3-1 kernel. Anyone know what can I do with that matter?

I just installed my first archlinux on new laptop (ThinkPad T520).

Re: Intel Advanced-N 6205 (ThinkPad T520) - Microcode SW error detected

This started happening recently after the kernel update.
Switch back to one of the recent-old kernels like 3.2 something.

The problem begins with:
HW problem - can not stop rx aggregation for tid 0

The greatest threat to knowledge is not ignorance - it is the illusion of knowledge!
