I tried set country via
iw reg set TWand via /etc/config/wireless and reboot router - no matter, ath9k ignore this settings.root@lede:~# iw reg get global country TW: DFS-FCC (2400 - 2483 @ 40), (N/A, 30), (N/A) (5150 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW (5250 - 5350 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW (5470 - 5725 @ 160), (N/A, 23), (0 ms), DFS (5725 - 5850 @ 80), (N/A, 30), (N/A)phy#0
