You can right-click on the LAN connection and then Check the 'Status'. That will give you the link speed. You can also open a command prompt and run ping.exe to ping other computers on the network. Link speed doesn't reflect the actual speed of the network.
Here is a few steps i would do in order to find the problem and test network speed: First, make sure that the links between your NAS and network is correctly beeing displayed as gigabit and that your cable are OK. Then i would try to transfer files using another protocol.
Download the version for your OS. On one of the computers run iperf -s (this is the server) and on the other run iperf -c <server hostname or IP> (this is the client). Then wait for the results. There are many options to tweak the measuring. Check iperf -h for a complete list of options. This was a useful reference for me on how to use iPerf ...
4. It could be not only network issue, but if you need to check the network speed, I would suggest use iPerf utility: https://iperf.fr/ It is cross platform tool which should work fine in your scenario. You have to run iperf on one side as server and on another one as a client. Share. Improve this answer.
Set static IP address for PC A. Set static IP address for WAN port of the Router (your router configuration must support this) On PC A start the server: iperf3 -s. on PC B run the command : iperf3 -c 192.168.2.30 (replace IP as required) The result may look like this (on the sender) when the speed is 95 Mbps: Share.

wmic NIC where "NetEnabled='true'" get "Name,Speed" (The where clause, and any get attribute (like Name and Speed), must be enclosed in double quotes and comma-delimited). // Edit #1: GET expression Name,Speed has to be enclosed within a single set of double quotes. Get expressions may not have a space between them
4. You have gigabit ports connected to a 100 megabit switch (or equivalent device). GBE = Gigabit Ethernet. The 100 megabit will be coming from the speed negotiated with the switch or equipment on the other end of the link. The cat5 cabling is probably not relevant - most cat5 cables will negotiate a gigabit connection (but you might not get ...
To test the maximum bandwidth of a network cable, do the following: Install iPerf on two computers, then connect both to opposing ends of the cable. On one of the computers, start iPerf in Server mode: iperf -s. On the other computer, run iPerf in client mode to test the connection: iperf -c <IP of server>.
177 1 11. 3. iperf to test plain network speed. Use ftp transfer of big continuous file to test network speed + writing to NAS drive. Small files will slow down transfers. If you got acceptable speed over ftp then tweak samba settings to improve throughput. Cables very rarely improving speed, it is either working or not.
A netstat -s command will provide some additional information on errors. E.g., in regards to the possibility of a fragmentation problem, there is a "Datagrams Failing Fragmentation" count. C:\>netstat -s. IPv4 Statistics. Packets Received = 265412964. Received Header Errors = 0.
