I bought a Cisco RV320 dual-WAN Gigabit VPN router that keeps freezing after about 12 hours or so of use. On the System Summary page, it shows that it is a RV320-K9 v03, firmware version 1.3.2.02. I have several other Cisco RV320s that work perfectly. They are RV320-K09 v04, firmware version 1.3.1.12. I downloaded and attempted to apply the 1.3.1.12 firmware to the V03 router, but after the reboot, it still showed v03, 1.3.2.02.
There are a plethora of RV320 firmware options at https://software.cisco.com/download/home/284005929/type/282465789/release/1.5.1.13
As far as I can tell, none of them specify whether they are for v03, v04, or what. I don't know whether the 1.3.1.12 firmware failed on the v03 because that version only works on v04, or because it's an older version. I am averse to blindly downloading other firmware versions and would rather see if someone has some specific knowledge about this.
