Description Steko95 2026-09-16 19:34:59 UTC 
Environment:

Fedora 44
Kernel 7.2.5-200.fc44.x86_64
NetworkManager 1.56.1-2.fc44
wpa_supplicant 2.11-9.fc44
Realtek RTL8922AE
driver rtw89_8922ae
firmware 0.35.80.3
Wi-Fi 7 / 802.11be with MLO active on 2.4 GHz + 5 GHz

I was seeing network stutters during multiplayer gaming approximately every 5 minutes. Tracing showed that they occurred exactly when NetworkManager triggered a background Wi-Fi scan. During the scan, rtw89 stopped TX queues and the ping to the local gateway stalled.

NetworkManager upstream already contains the fix:

“Keep the long background scan interval for a single Wi-Fi 7 AP-MLD.”

The workaround is to lock the connection to a specific BSSID, which disables the periodic background scan. After applying it, MLO remains active and the stutters disappear completely.

Could this AP-MLD/background-scan fix be backported to the NetworkManager package shipped with Fedora 44?
