Issue with Intel(R) Wi-Fi 6E AX211 160MHz Online Gaming

[wnc]

Hello,

I'm struggling with gaming while connected to wireless 5GHz network. Issue is the same like in this topic:

https://community.intel.com/t5/Wireless/Running-into-an-issue-with-Intel-R-Wi-Fi-6E-AX211-Online-Gaming/td-p/1511447

Downloading / opening web pages works perfectly, issue shows up everytime i play online games. Here you can see how playing Call of Duty looks while I'm on 5Ghz network:

And this is a screenshot from command line window, with ping to some server, that usually have ~8ms ping, but took in same time as video above (during gaming attempt).

To be able to play, I need to use 2.4GHz network or plug in ethernet cable.

Other computer, which network card also supports AX connections does not have this issue with my 5Ghz network.

I've followed every step from other topic I've mentioned befor (BIOS update, clean reinstall of network drivers, windows update has no new updates, AP firmware is also up to date, recommended settings for 802.11ax connectivity is set like in your guide).

I'm also sending logs from Intel System Support Utility for Windows.

Please help 🥺

Quick update for all, that have same issue with their WiFi card.

Steps that helped me fix this:

1. Clean install of drivers - guide here
2. In the advanced properties network adapter, I've changed the bandwidth setting from Auto to 20 MHz for 5 and 6 GHz.
