qtr: if MD5 hash is the same, they're (with a very high degree of certainty) the same. No need to check further. What were your before and after values for the power output on the low 5GHz channels (e.g. 36 and the few above that, the ones under 100)? Should have been 17dBm before, and 23 after. Power limit of 20dBm is pretty common around the world for the 2.4GHz channels, so wouldn't pay too much attention to that.
I may be wrong here, but I think passive scanning means it can look for a router SSID running on that channel, and if it finds one can connect to it but that it can't signal prior to finding local infrastructure on the channel. Not much good for running an AP, but handy if you take your laptop overseas and are looking to connect to one...
My output from iw list is (on 2.4GHz):
Frequencies:
* 2412 MHz [1] (20.0 dBm)
* 2417 MHz [2] (20.0 dBm)
* 2422 MHz [3] (20.0 dBm)
* 2427 MHz [4] (20.0 dBm)
* 2432 MHz [5] (20.0 dBm)
* 2437 MHz [6] (20.0 dBm)
* 2442 MHz [7] (20.0 dBm)
* 2447 MHz [8] (20.0 dBm)
* 2452 MHz [9] (20.0 dBm)
* 2457 MHz [10] (20.0 dBm)
* 2462 MHz [11] (20.0 dBm)
* 2467 MHz [12] (20.0 dBm)
* 2472 MHz [13] (20.0 dBm)
* 2484 MHz [14] (disabled)
and on 5GHz:
Frequencies:
* 5180 MHz [36] (23.0 dBm)
* 5200 MHz [40] (23.0 dBm)
* 5220 MHz [44] (23.0 dBm)
* 5240 MHz [48] (23.0 dBm)
* 5260 MHz [52] (23.0 dBm) (passive scanning, no IBSS, radar detection)
* 5280 MHz [56] (23.0 dBm) (passive scanning, no IBSS, radar detection)
* 5300 MHz [60] (23.0 dBm) (passive scanning, no IBSS, radar detection)
* 5320 MHz [64] (23.0 dBm) (passive scanning, no IBSS, radar detection)
