RESOLVED: WiFi Speed does not go over 100Mbit on OpenWRT

Hello,
I've installed OpenWRT on Linksys WHW01.
Version OpenWrt 23.05.0.

Speedtest directly on router:

server selected profile detected: profile selected from server configuration

Download: 557.02 Mbit/s
Upload: 461.34 Mbit/s

Now a PROBLEM:

When i connect to this router by network to eth
Signal is OK

Tx Rate: 866bit

And run speedtest.net

The speed is

Download: 100~110Mbit
Upload: 150-200Mbit

:((((

What could be the issue?

Software flow offloading is OFF. When ON - it does not have any effect.

It seems the issue is on packet routing level. Because when connecting through other router to LAN eth port, i get same issue

what version are you actually running ?

how about you start by installing a stable release ?

@frollic I just updated all to stable version and updated the post. the issue is still there

All wired connections seem to be OK and on 1Gbit speed

ksoftirqd/2 CPU usage goes to 25% during speedtest performed from LAN
It stays 0-2% when speedtest is performed directly on router

Looks like its related to hardware offloading. I created new topic.
