Hi,
I am operating Linksys WRT1900AC with
OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.136.49537-fb2f363
The issue is that if i execute a speed test.net (internet speed test) on pc connected to router wirelessly i get 300/20 ... but executing same test on same PC connected to ethernet port directly to router its around 150-200 / 20 ... so i i also executed on other device connected to other ethernet port and its the same ...
is there some ethernet speed limitation or bug/ issue?
thanks

What is the internet speed your provider gave you?
It's hard to say if the numbers are correct if the scale units are missing.
Sth. like MiB, MB, MBit. So pls. check.
You could also make a test within your LAN if your ethernet port is working correctly. Just copy large files between some clients.
@pwned
its 300/20 MBit
what i am saying via devices connected to eth port its 150-200 MBit max... so it has to be bug or i dont know.

There are several things to check before:
Did you try different lan cables? What kind of cable you are using? It has to be at least a CAT 5e.
Did you try to use a different LAN port on the router?
If you checked this you can dig a bit more:
Check the logs if there are failures
Reset your device (if you made changes recently)
This is not normal, ethernet should be faster, unless you did something really weird with the configuration. Have you tried with another cable?
yes its not normal, tried different cables + different endpoints.
What is the speed between two devices on LAN? And between one device and the router?

is that really important? dont know how to measure it somehow easily probably ipfert or something ...
Yes, is important if you want to figure it out.
You could use iperf how described there.
You could run iperf3 on the router as server and test with the PC as client to check your LAN connectiviy.
Also check the CPU load with htop on the router.
# opkg update && opkg install iperf3 htop
Start the server.
# iperf3 -s -V -D
Start htop to monitor CPU load when you speedtest your Internet or your LAN:
# htop
Start htop as client on the PC
iperf3.exe -c [IP address of your router]
These are the results from my PC with a Linksys WRT1200AC.
iperf3.exe -c 192.168.90.254

I wanted to determine where exactly is the issue.
