Hi. I do have a TP-Link Archer AX23 v1.20 WiFi 6 Router running latest release (not snapshot) of OpenWrt. I get very slow download speeds, under 10Mbps WiFi speeds on Windows 10/11. This doesn't occur on Linux/FreeBSD OSes but only on Windows. Recently I installed stock TP-Link firmware on AX23 and it was giving perfectly fine WiFi download speeds on Windows. I think I've tried everything that I found in this case-like topics to get it working fine on Windows but no success. I do currently have OpenWrt installed on AX23. 2.4GHz seems to give higher download speed than 5GHz. Thanks in advance.

Try PSK2 on 5 Ghz. Possibly also forget the network on the windows machine before reconnecting.

Thanks for your reply. I think I was tried it once already but tried again and still I am getting download speed under 10Mbps, currently 5.9Mbps. Btw, i don't have windows installed, just using WinPE which is hiren's boot cd and in wifi list window, i see that 5ghz AP's radio type is showing 802.11ac and when i connect to it, i just see 802.11n. Just got 36Mbps download speed on 2.4GHz. My link is 100/50. FYI, I remember that I saw, in wireless section of luci, that tx rate of my windows client had 14mbit/s speed.
Do not use sae-mixed. If you really need wpa2 and wpa3 make 2 access points per band, one wpa3 one wpa2 , can even be with same name and password. old devices will not "see" wpa3 one and new devices wil lock on wpa3 due to downgrade protection.
Which channel is used in 5GHz? iwinfo ?

I already have 2 APs in total, one is 2.4GHz and other one is 5GHz. 2.4GHz AP's SSID just has 2.4GHz mark. Thanks for the hint.
EDIT: Oh, you said 2 APs per band, so i guess i can have 2 APs in each band?

Strange it selected relatively busy channel, while in web ui - restart 5ghz radio to re-select channel.

I don't know much about WiFi channels but it picked up channel 132. My pc isn't able to see 5GHz AP now while my phone connected to it, strange.

Are client regional settings correct?
Did you mean country code for AP? They are both set to TR which is country I live in, Turkey. If you meant that client's (Windows) regional settings, I don't know, how can I check?
Hiren's Boot CD got crazy (?) and was not connecting to both APs. I switched to FreeBSD and these are the speed results.

Your client is wifi-a, 300Mbps link speed?
Your client netcard is wifi4 level.

Thanks but I don't know what that means, so, is it a reason for not getting full speed on Windows while it works on other OSes? Maybe because my router is wifi 6?
Well, what link speed is windows indicating? You might need to reinstall/upgrade drivers.

I guess it was 144/144 and when there was tp-link firmware, it was 300/300 if i recall correctly.
Looks like only one antenna is employed, check drivers, as you measured yourself no broken hardware involved.

I was tried installing a different version of driver from driverpack.io and it was still same. 
It works under freebsd, ask closer to microsoft / wifi manufacturer. Dropping to one antenna from two sounds a bit too wild for powersave.
