What have you looked at? There should be no obvious reason for you to change any of the LMIC files to setup regional settings.

Please can you stop posting screen shots by default, particularly of web pages that can be linked to. If it’s a log, it should be copy & pasted as text. See [**here**](https://www.thethingsnetwork.org/forum/t/how-do-i-format-my-forum-post-howto/8735) on how to format posts.

Here are three things to do:

1. Post a copy (as text) of your lmic\_project\_config.h so we can see the regional settings in use.
2. Set #define LMIC\_DEBUG\_LEVEL to 1 in config.h so you get more debug output and then post it (as text) showing from power up to join fail or downlink fail.
3. Post the gateway log (as text) for the corresponding time period.
