Transfer limit on both lan and wlan

[MILWIS]

Hi. 

 

I have problem with my dell xps 15. When I use wifi or ethernet (via USB3.0 adapter) I get only 100mbps speeds. Ethernet connection shows 1gbps connection and wifi is 866,7mb/s but on both there is only 100mbps transfer to and from the NAS. When it comes to the Internet connection it's fine- 300mbps. NAS is not connected with 100mbps becouse on every other device it goes 1gbps. Also disk in XPS is not bad becouse it's NVME and it works fine with for expample samsung t5. When i connect it via usb 3.0 it should be like 40-50MB/s not 10... and why it is exactly the same on wifi? I have no idea right now. Please let me know what do you think it can be.

Run iperf to the nas, what speeds do you get?

 

What is your network diagram?

It seems exactly like between this two devices there is a 100mbps bottleneck or weak cable but there is not...

what is the network diagram look like? Really looks like a 100m link.

 

What if you connect a cable directly from nas to your laptop?

Didn't try it yet. What diagram do you mean?

network diagram. How is your home network layed out.

 

What switches, what port speeds do those switches report?

I always used 1gb switches, routers and access points. Cables only 5e and 6cat. Right now I tried something like this. I unplugged ethernet cable from desktop lan port which get 1gbps to the nas and plugged to xps using ue300. 100mbps again. XPS to the Internet via the same cable 300mbps. Plugged back to the pc and back on 1gbps. Both in ethernet connection details shows 1gbps.

Tommorow I'll try to connect directly to nas and we will see if it's laptop/ adapter problem or something between in the network.

what speed are the ports running at? The cli of the switch should show you, otherwise look at the lights near the ports.
