I have the same problem. I am running the firmware v1.5.1.05. I have noticed that since I have installed this firmware, the unit respond super slow until the web interface stops responding, in my case, happens every 3 or 4 months, so, I have to shut down the unit using the power switch. It will be great if Cisco allow us to set a cron job to reboot the unit as I do with my UniFi EdgeRouter X. If somebody knows how to set a cron job to reboot the Cisco RV325, please, share it.
