|Architecture|ARMv7 Processor rev 0 (v7l)|
|Target Platform|ipq806x/generic|
|Firmware Version|OpenWrt 24.10.2 r28739-d9340319c6 / LuCI openwrt-24.10 branch 25.168.50434~d6b13f6|
|Kernel Version|6.6.93|

if i can improve somthing tell me

My two cents:

  • Use an ethernet cable
  • Do not use a VPN

Then try again, removing any other device in your network but the PC, and removing any unneeded intermediate device in the traffic path.

For QoS tuning you need to do measurements with cable. wifi is different beast.

What is he report for a wired up client? You can paste link, it does not lead back to your IP/home.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):

Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/wireless
cat /etc/config/firewall

That is too much for sqm on ipq8065. for sqm/cake it maxes out around 120 MBit/s (or slightly less). ipq806x/ ipq807x/ ipq50xx/ ipq60xx was designed with proprietary hardware offloading (NSS) in mind, which will never be supported by OpenWrt - without that, its routing (and even more so sqm-) performance is far from stellar. sqm really doesn't like running out of CPU cycles, you'll end up worse than without it.

If you're looking for improvements, you will have to (considerably) upgrade the router.
