I was racking my brain on this one for a while until I noticed the Windows 11 machine that was working was older WIFI Card. Newer Windows 11 machine has the Killer(R) Wi-Fi 6E AX1675i 160MHz Wireless Network Adapter.


I searched the web and found this thread.


When I loaded the "Killer Intelligence Center" I noticed warning messages indicating that my router is not compatible with newer capabilities on this Killer WiFi Card.


Work around:

  1. Right click start and load Computer Management
  2. Find Killer Services under the Services and Applications
  3. Set both Killer Network Service and Killer Analytics Service to Disabled
  4. Find both these services in task manager and stop the both
  5. Log into icloud.com without issue; Joy!


Thanks rivrbend!
