Hardware: Intel **Galileo** Gen 2 System: **Yocto** linux (iot-devkit-image) User: root # iw reg set JP # iw reg get global country 00: DFS-UNSET (2402 - 2472 @ 40), (6, 20), (N/A) (2457 - 2482 @ 40), (6, 20), (N/A), NO-IR (2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, NO-IR (5170 - 5250 @ 40), (6, 20), (N/A), NO-IR (5735 - 5835 @ 40), (6, 20), (N/A), NO-IR (57240 - 63720 @ 2160), (N/A, 0), (N/A) # iw list Frequencies: * 2412 MHz (20.0 dBm) * 2417 MHz (20.0 dBm) * 2422 MHz (20.0 dBm) * 2427 MHz (20.0 dBm) * 2432 MHz (20.0 dBm) * 2437 MHz (20.0 dBm) * 2442 MHz (20.0 dBm) * 2447 MHz (20.0 dBm) * 2452 MHz (20.0 dBm) * 2457 MHz (20.0 dBm) * 2462 MHz (20.0 dBm) * 2467 MHz (20.0 dBm) (no IR) * 2472 MHz (20.0 dBm) (no IR) * 2484 MHz (20.0 dBm) (no IR) Notes : - "iw" not installed by default on Yocto, so i compiled it from source code. - All i want enable wifi channel 14. - "iw" and same wifi adapter work good on Ubunte 17 (without no-IR flag). **How to** fix "iw", or any other way to **enable channel 14**, or **remove no-IR flag**?
