Ĭan Jio Fiber Router give 1 gbps over Wifi to my PC? This can help you to determine if the problem lies between your computer and the modem, or the modem to the internet.Ī great way to test raw throughput and read/write speeds on your home network is to use Lan Speed Test. How are you testing your connection? For internet speeds use I use to test speeds for my LAN.Īfter a quick search and a test, you can also use This program to test the speed between your computer and your LAN. I've used Lan Speed Test by Totusoft to narrow down degraded network performance between devices on a LAN to a smaller area of troubleshooting. Like mentionned, you can always connect to the box directly by using static ip, bypassing your whole network to make sure that's not the problem.As far as stress testing i/o and network, I'm unsure, never had to test it. Faulted drive in a RAID array can cause performance issue while still beeing functionnal. If it's faster using FTP, you can then try different SMB configuration to get the speed you should be getting.

Try to use FTP for example, which is usually faster. Sometimes Synology NAS are using conservative config like suporting SMBv1 and SMBv2 which are slower.

You didn't mention it but i'm guessing you are using SMB to transfer files, which is not the fastest transfer protocol out there.

Then i would try to transfer files using another protocol. Here is a few steps i would do in order to find the problem and test network speed:įirst, make sure that the links between your NAS and network is correctly beeing displayed as gigabit and that your cable are OK. Ideally always test with a wired connection to limit factors (wifi interference). I've seen a couple of ways to get this running on synology, one beeing to run a docker container with iperf ( ). But you have to install on both machine testing the link (client/server). If you want to test pure network speed, iperf is the tool to have ( ).
