Intel 5300AGN with not operable 11n

I've seen this problem describe for older (2.6.x era) kernels, but didn't find any info for recent ones. I'm using 3.7.9.

iw dev wlan0 link

freq: 2417
	RX: 69541 bytes (494 packets)
	TX: 7074 bytes (51 packets)
	signal: -77 dBm
	tx bitrate: 1.0 MBit/s

	bss flags:	short-preamble short-slot-time
	dtim period:	1
	beacon int:	100

The router is set to use wireless n with WPA2-PSK.

Setting the following in /etc/modprobe.d/iwlwifi.conf works as expected speed-wise. I still get drop-outs though.

options iwlwifi bt_coex_active=0
options iwlfifi 11n_disable=1

    freq: 2462
    RX: 8802143 bytes (11596 packets)
    TX: 1062732 bytes (5687 packets)
    signal: -70 dBm
    tx bitrate: 43.3 MBit/s MCS 4 short GI

    bss flags:    CTS-protection short-preamble short-slot-time
    dtim period:    1
    beacon int:    100

I can't remember when this situation started, but I'm sure somewhere in the 3.x era.
