I have updated two RUT240 to firmware 7.01. Everything worked normally (i installed ddns & snmp, it was tricky but worked somehow). After 5-10 reboots and ~ 2 hours later I wasn't able to start one of the routers.
The "signal strength" LEDs are flashing 5 times. After that they stay "green" for ~2 sec. then all LEDs are turning on green for ~4 sec. And the process is repeating itself.
Same problem for the other RUT240.
Any Ideas? Even after resettings to factory default this behaviour starts again.
Best regards
