Wi-Fi frequency bands are regulated country by country: Japan allows channel 14, most other countries do not; North America forbids channels 12 and 13. Setting the right country code guarantees that your Recalbox uses the frequencies allowed where you live.
Recalbox defaults to
JP. It is the most permissive value, the one that connects to the widest range of access points without any configuration. You only need to change it if your Wi-Fi connection does not work, or to comply with the regulations of your country.
| Channel | Frequency (MHz) | North America | Japan | Rest of the world |

| 12 | 2467 | ❌ | ✅ | ✅ |
| 13 | 2472 | ❌ | ✅ | ✅ |
| 14 | 2484 | ❌ | ✅ (802.11b only) | ❌ |
