TRB500 running old modem firmware

Hi,

My TRB500 is dropping in connection speed after some hours of use. I’ve tried to put it to passthrough instead of NAT which seems to have improved the connection, but still not stable. I noticed the modem firmware it’s running is “RG501QEUAAR12A05M4G_OCPU_BETA-20211020D-04.001.00.000” which seems very old. Is there a way to find a stable firmware update?

@Vilius Could you please help me with the modem firmware for my TRB500?

Is there no way to update the modem firmware? I’m relying on the TRB500 for work and need the connection to be stable. Can’t continue to restart it several times a day. Is there any other product that is more stable than the TRB500? How about the RUTX50 or the TRB501?
