My RUTX11 failed to come online after a power failure. When I checked, I saw the 5 signal-strength LEDs blinking approximately once per second.
I tried power off, power on (even with a week inbetween), tried the various RESET options documented in the manual, tried with the SIM card in slot 1, slot 2, completely removed. Always the same. After about 10-20 seconds of normal boot behavior, the five signal-strength LEDs start to blink at ~1Hz, and that’s it.
The behavior you described - all five signal LEDs blinking at roughly 1 Hz after the initial boot - is a documented “fatal boot error” on the RUTX11. This indicates the router is unable to complete its boot process, usually due to one of the following causes:
Corrupted firmware – it might have occurred due to a sudden power loss.
Failed NAND/flash memory – preventing the bootloader from loading the OS.
Hardware failure on the board – less common, but possible if a component was damaged.
Before considering hardware replacement, you can try the following steps:
Use a different power supply (PSU) to rule out power issues.
Flash a fresh firmware image via the bootloader menu.

Step-by-step instructions for flashing the firmware using the bootloader can be found here:
If these steps do not resolve the issue, it likely points to a hardware failure, and I recommend contacting your reseller to initiate the RMA process.
