Many users have complained that their Windows 11-enabled notebooks and PCs are having WiFi problems, which was later identified to be caused by December 12th’s KB5033375 security patch rolled out via Windows Update. This update is affecting 802.11r ‘Fast Roaming’ adapters, mostly made by Qualcomm and MediaTek.
What makes this issue annoying is that the 802.11r standard uses a feature called Fast Basic Service Set Transition (FT) which allows users to move from one access to another access point while having continuous wireless connectivity.
