Wifi region question

I've recently been trying to tidy up my network by switching as much as possible to wifi. A couple of devices gave surprisingly slow connections, considering they were connecting at 5GHz with very good signal quality readings (link quality 69/70).

A quick look through the settings revealed that both were running with default region settings.

I've included a short script in /etc/modprobe.d/ to force the module on to the right region, and things have improved. I still have one question, though:Code:iw reg get
global
country GB: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 20), (N/A)
(5150 - 5250 @ 80), (N/A, 23), (N/A), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (N/A, 20), (0 ms), NO-OUTDOOR, DFS, AUTO-BW
(5470 - 5730 @ 160), (N/A, 26), (0 ms), DFS
(5725 - 5850 @ 80), (N/A, 23), (N/A), NO-OUTDOOR
(5925 - 6425 @ 160), (N/A, 23), (N/A), NO-OUTDOOR
(57000 - 71000 @ 2160), (N/A, 40), (N/A)

phy#0
country 99: DFS-UNSET
(2402 - 2482 @ 40), (6, 20), (N/A)
(2474 - 2494 @ 20), (6, 20), (N/A)
(5140 - 5360 @ 160), (6, 20), (N/A)
(5460 - 5860 @ 160), (6, 20), (N/A)Am I right in thinking that "global" takes priority over "phy#0"?

I'm assuming the "phy#0" is what is baked into either the wifi firmware or kernel module, and that when I set the "global" setting that will take priority.

What is puzzling me is that my laptop has "GB" for both settings (GB is correct).

Cheers,
