    Just a report to say that I still see those in 3.5.0-rc5.

    I recently moved from a Dell Latitude 6400, with a bcm4322 chip managed
    by the Broadcom-STA out-of-tree driver (wl module) to the new Latitude 6420,
    which has this as per lspci:

    02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34)

    and I have two issues compared to the bcm4322; one is the above message,
    which appears when the driver can't associate to my D-Link DSL2740B router;
    telnetting into the router and bouncing its AP component via wlctl is enough
    to allow the laptop to connect again.
    At the same time, my wife's old 32-bit Dell D610 with an ipw2200 connects just
    fine to the DSL-2740B.

    The second issue is that the wifi speed is much lower with the new 6420 under
    iwlwifi - topping out at under 3MB/s compared with peaks of 10MB/s with the
    bcm4322's wl driver, which hardly ever went under 6MB/s.

    iwconfig wlan0 reports fluctuating bitrates of 18/24/36 Mb/s whereas I could see
    very easily 130Mb/s with the wl driver. Maybe something is also due to the fact
    that the DSL-2740B has a draft-N implementation and its Broadcom chip has
    better feelings with the laptop's Broadcom wl than the iwlwifi.

    I'm available for more detailed reporting and testing.
