Transfer quota available for both LAN and WLAN connections.
Hi. Your Dell XPS 15 seems to have inconsistent speeds depending on the connection method. On Ethernet via USB3.0, you're getting only 100Mbps, while the display shows 1Gbps and Wi-Fi reports 866.7Mb/s. However, both connections transfer just 100Mbps to and from your NAS. The internet connection works at 300Mbps, but the NAS doesn't reach 100Mbps regardless of other devices. Your SSD is performing well, as it supports NVME and works with devices like the Samsung T5. When using USB 3.0, speeds drop significantly to 40-50MB/s, which matches what you observed on Wi-Fi. It’s possible the USB port or driver settings are affecting performance. You might want to check the network adapter drivers or try a different port.
Execute iperf to the NAS, which speeds are you observing? Share your network diagram details.

It appears the connection between these two units has a 100mbps limitation or a poor cable, yet it doesn't show that issue.
The network layout appears similar to a 100-meter connection. If you link a cable straight from the NAS to your laptop, it could simplify the setup.
You mentioned a diagram but didn't specify which one. Could you clarify what you're referring to?

I previously relied on 1gb switches, routers, and access points. Cables were limited to 5e and 6cat. Now I experimented with a setup. I removed the Ethernet cable from the desktop LAN port which provided 1gbps to the NAS and connected it to the XPS via UE300. It then reached 100mbps. The XPS connected to the Internet through the same cable at 300mbps. After reconnecting to the PC, both Ethernet settings displayed 1gbps.
