Checked the latest image. Downloaded from the website (something to make sure that the file on the website is not corrupted). Recorded on the flash drive. Launched on VIM. Then show a video of my actions. The system found the available network, I enter only a password to connect. Pay attention - I not change Android, I just added multi-upload (via UART console, it’s easier and immediately see the result). The dtb file is used from internal memory. Maybe you have to handle the case could disconnect the antenna or broke the contact. Or use the dtb that is different from the regular one. Either the router is spelled out binding to MAC to the address, and he changed. Ideas from me yet.
