First stab: It seems with 217, the card is waiting for getting its firmware loaded:

+E: FIRMWARE=iwlwifi-6000-5.ucode
+E: SUBSYSTEM=firmware
+E: TIMEOUT=60

and dmesg shows:

[ 6.586593] iwlwifi 0000:02:00.0: Direct firmware load failed with error -2
[ 6.586598] iwlwifi 0000:02:00.0: Falling back to user helper

which seems to correlate with this in the 217 changelog:

        * Userspace firmware loading support has been removed and
          the minimum supported kernel version is thus bumped to 3.7.

so it seems we found a case where the in-kernel firmware loading does not work.

I have iwlwifi as well:

03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)

and my dmesg says

[ 2.898239] iwlwifi 0000:03:00.0: loaded firmware version 18.168.6.1 op_mode iwldvm
