Killer WiFi 6 AX1650i driver error

[davidcoffey]

I am on Windows 11 Home 24H2.   After the a recent upgrade my system will no longer connect to the 5ghz wireless network whle the 2.4 ghz wireless still works.     I have installed/reinstalled the killer drivers to no avail.   Guidance needed to get the 5 ghz wireless working again.  

Have tried manually installing the latest killer drivers, tried a rollback.....  nothing seems to address the issue.

Device manager shows the following error:  

Device settings for PCI\VEN_8086&DEV_06F0&SUBSYS_16521A56&REV_00\3&11583659&0&A3 were not migrated from previous OS installation due to partial or ambiguous device match.

Status: 0xC0000719

Desktop or Laptop?  Desktop system.  Dell XPS 8940

Original adapter? Yes 

Checked other networks?  No, I have not.  All the other 5gig devices on my home network work as expected and show no issues.  This is the only device that cannot connect to the 5gig network. 

Recent upgrade?   Win 11 24H2 on 1/31/2025 but this was after this problem showed up.   There are 3 cumulative updates: 2025-01 on 2/27/2025 (after the issue showed up) and 2025-02 on 211/2025 and then 2024-12 on 12/17/2024, newest to oldest.   Could be one of these two....    I don’t have a specific record when it showed up because my system defaulted to the 2.4gig network and it was not noticed immediately. 

Drivers?  I have installed both the Intel supplied driver set and then the Dell supplied driver.   Prior to the install of the Intel driver set I completely deleted and uninstalled the Killer app and all services.  KillerPerformanceSuite_36.24.12162_Win10-11x64.exe (Intel I think) and then Killer-BE1750-AX1690-AX1675-AX1650-and-Intel-BE202-BE201-BE200-AX411-AX211-AX210-AX201-AX200-9560-9462-9260_P766C_WIN64_23.90.0.8_A51_03.EXE  (Dell) 

Additional Comments:  My SSIDs are mercury-24g and mercury-5g    Only mercury-24g shows active in the report.   The 5gig radio cannot connect to my network, hence it is not in use and not shown.

I have installed the rcent driver, dated 3/4/2025.   There is no change in the behaviour.   I complted the automated install, rebooted my computer and the 5gig network was visible.   I switched the connection, supplied the password and the message dispoayed was "Unable to connect to the network.    

No improvement.
