I just get new device SXT2G. It has 6.39.2 routerOS installed, and it was losing all configuration changes after reboot. I did upgrade to latest version and the bug was fixed. I have configured WISP AP via quick settings. AP was working, but I lost access to webfig. Then I did reset device. I succeded after 3 times repeating reset procedure. Then I did minor changes and apply config with default 192.168.88.1 bridge settings. And I was lost webfig again. Then I was fail to reset device after 5 attempts. The reset procedure I did exactly as follows https://www.youtube.com/watch?v=JfPOpypuJjc. Please give advice what to do. Is it a hardware defect?
Thanks.
