Download speed is 2 times slower compared to upload on 5 Ghz. Asus AX6000

Installing and Using OpenWrt Network and Wireless Configuration
1

Hey!

I have flashed openwrt into my Asus TUF-AX6000 router. I did the basic configuration (selecting the correct channels, transmit power, width, etc.) for 2.4 and 5 Ghz. I have 1 Gbps fibre

2.4 GHz settings:

  • AX / 13 / 40 MHz
  • 30 dBm
  • Everything else on default

5 GHz settings:

  • AX / 128 / 160 MHz
  • 30 dBm
  • Everything else on default

On 2.4 GHz i'm getting (1m from router):

  • 100 Mbit/s on Download
  • 100 Mbit/s on Upload

On 5 GHz i'm getting (1m from router):

  • ~ 570 Mbit/s on Download
  • ~ 940 Mbit/s on Upload

Is this behaviour expected or could there be a problem somewhere? I have tested it on several devices (iPhone Pro Max 15, Mac M1, Apple TV, Ugoos AM8), the result is always the same, the download speed does not go over 570 Mbps.

Please post

ubus call system board
cat /etc/config/wireless

cleaning access codes and MAC addresses.

What other clients casually connect? Wifi AN would consume lots of airtime from all due to omnidirectional nature?

Try execute nft flush ruleset before speed test

After executing this, the ethernet connection has been lost.

service firewall restart
