Hi all, I own a TM-AC1900 (T-Mobile rebranded RT-AC68U). I followed the tutorials carefully and was successfully able to flash it with Shibby's Tomato firmware, specifically tomato-RT-AC68U-ARM--138-AIO-64K. I made sure to clear the NVRAM after the firmware process was completed. I noticed that whenever the power goes out, or if I manually reboot the router, all of my settings are lost. I would then have to log in and reconfigure all of my settings. This has been been a problem ever since I flashed my router to Shibby's Tomato firmware. Is there a compatibility issue with my router? Any help would be much appreciated. Thanks!
