I am experiencing some stability problems after going to firmware RUT2_R_00.07.01. My deployment requires IPv4/IPv6 on the mobile interface, so I have this enabled. Randomly, and infrequently, the RUT 240 goes down with lights flashing. After that there is no IPv6 address on the mobile interface, only IPv4. Even after a reboot IPv6 does not work, I need to return to IPv4 in the mobile interface configuration and then change it to IPv6/IPv4 again for it to work.
Any idea what may be wrong?
