Kirkwood-linksys_ea4500, OpenWrt 21.02.0-rc2, laggy Wi-Fi connection

Hi,

Right after I updated my router to 21.02 I already noticed there's considerable lag at times when trying to operate LuCI or browsing the Internet. Since it initially felt intermittent I thought this might be some performance-related issue.
After having used the router for some time I now have a better understanding of the characteristics of the problem.

Basically, it appears the lags only occur after the Wi-Fi connection was idle for a certain period of time. If the Wi-Fi connection is being kept busy, then there is no problem. The tipping-point seems to be around 8-9 seconds.
The 2.4 GHz radio and 5 GHz radio are equally affected.
I can't recall having had such issues with any versions of LEDE/OpenWrt up to version 19.

Is anyone else here running OpenWrt 21.02 on EA4500 hardware yet?

In an attempt to "visualize" the issue I made a small PowerShell script that repeatedly copies a file (13 MB) from a USB drive plugged into the router to my Windows PC, with a pause between the file copies. It measures the time it takes to copy the file and logs the result.

First log -> 5 seconds wait between two file copies over Wi-Fi:

I used to have an ea3500 which is basically the same device (4500 just has a bit more memory if I remember right) and it was always necessary to disable the Disassociate On Low Acknowledgement option which sounds like the problem you're having, the last time I used OpenWrt on the ea3500 was the 17.* builds, so I'm not sure if it will still solve the problem, but worth a try, you can find the option in Luci>Network>Wireless>Interface Configuration>Advanced Settings.

Thanks for the tip.

I disabled "Disassociate On Low Acknowledgement" for both wlan interfaces, but unfortunately in my case it doesn't solve the problem.

However, it has turned out that the problem is Wi-Fi card specific. If I disable the Intel AX210 card in my computer and instead use an external USB Wi-Fi adapter with Mediatek chipset, then there is no lag problem whatsoever.
I also noticed that when using the Mediatek Wi-Fi adapter the OpenWrt "System Log" is completely quiet, while with the Intel card in use the "System Log" is continuously being filled up with the following messages:
