I have one device (a Windows laptop with a docking station which provides an Ethernet port) connected to a router via a wired connection and a number of dropped packets is slowly increasing while the device is in operation. I have tried different cables and different router ports before without any success. The device is currently connected via a managed switch and then to a trunk port on the router and I am still seeing the same behaviour on a VLAN interface (lan1.20): a slowly (10+ per hour or so) increasing number of dropped packets. Tried different ports on the switch.
The router is wrt3200acm running 22.03-SNAPSHOT and only a single physical port utilized (VLAN trunk), which is in turn connected to a managed switch. The cable tester on the managed switch shows no issues and I also tried different cables; no dropped packets reported on the switch either.
Is there a way to figure out why the packets get dropped? Is it possible that some network buffers overflow? This is a work laptop and it has always has VPN active, so I would like to eliminate the dropped packets of possible.
