Connection limited to 100Mb speed.
Your network configuration appears to have one of the connections running at 100Mbps, likely because of a faulty cable or other issue.
It might be due to routers lacking gigabit ports or some connections not operating at that speed. Often the switch port has a status indicator showing its current speed, so inspect those.
Task manager network section displays the data in bits. The transfer period (as shown there) indicates no Windows file transfer, which means I cannot capture a matching snapshot. Windows transfers during those times usually register around 10MB per second.
It's not just a simple switch—it's a router switch with AP functionality. I've used some budget options recently. Trunk cables are those connecting devices to switches, then switches to patch panels. All of them use Gigabit Ethernet. That’s what I was looking at first.
trunk cables serve as connections between switches. If your PC and NAS both use 1Gbit, the obvious issue might be a link between basement and first floor not being 1Gbit. A faulty pair could force the interface to switch to 100mbit (100BaseTX only uses two pairs, while 1000BaseT needs all four). Try using a laptop connected to the switch next to the NAS to test speed. If it works, repeat with the PC side. Narrow down the problem by checking each connection step by step.
