Xiaomi r3p very slow wifi inside network

Installing and Using OpenWrt
1

im running latest openwrt image on a xiaomi r3p pro everything is working great
except for network speeds inside my network (maximum speed is 8mb/s average ~4mb/s)
but when i run a speedtest from the internet whilst connected to wifi i get :slight_smile:

strange@echelon:~$ sudo speedtest-cli

on ethernet i do get fast transfer speeds
any ideas?

asked for some help on irc and we ran some tests iperf3 inside network 30mbit or so
outside to an internet machine 500mbit

no QOS or SQM installed
no isolate clients enabled

and output of tc -s qdisc

How are you testing the speeds between the devices on your network? You mention slow WiFi speeds, but have you run tests wired-wired? wired-wireless? And wireless-wireless? What are the devices on each end? And what are the actual speeds for each test?

5

wired-wired = ~100mb/s
wired-wirelesss = ~50mb/s
wireless-wireless = ~7mb/s

devices: macbook pro 2019, lenovo t14 gen 1, raspbery pi4 8gb

scp is what i use to test

Try using iperf to run the tests. This way you don’t have read and/or write speeds potentially affecting the results. Test this using the two most powerful systems - the MacBook Pro and the Lenovo machine.
