Hi cam8528,

Thanks for reaching out to the Intel Community Forum! I appreciate your message and I’m here to help you out. Since both adapters show up correctly in Device Manager but aren’t detected by the Killer Performance Suite, it’s likely there’s some software corruption going on. To get a better idea of what’s happening and provide the right support, could you please share the following info:

What version of the Killer Performance Suite are you using? (You can check this in the app settings or under “About.”)
When was the last time you updated the Killer software and the drivers?
In Task Manager → Details tab, do you see any “Killer” processes running? Does the Killer Performance Suite briefly appear and then close when you try to launch it?
Have you used any PC cleanup tools or registry cleaners recently?
Are you running the Killer app using the same user account that installed it?

Also, please try this:

Open services.msc
Look for Killer Network Service and Killer Analytics Service
If either is stopped, try starting it manually — let us know what happens when you do.

To help us understand your system setup better, we’d also appreciate it if you could send us the Intel® System Support Utility (SSU) logs. These logs give us key details about your hardware and software environment, which are super helpful for troubleshooting.

Here’s how to do it:

Download and run the Intel® SSU tool
It will generate a text file with your system info
You can follow this guide for step-by-step instructions: Help Guide for the Intel® System Support Utility
Once done, please attach the file to your reply

If you have any other questions or need help with anything else, feel free to reach out!

Best regards,

Hi cam8528,

I’ll begin investigating this issue using the SSU logs you provided. However, to help further isolate the problem, please confirm whether you’ve already followed my previous recommendations:

Open services.msc
Locate Killer Network Service and Killer Analytics Service
If either service is stopped, try starting it manually and let us know what happens.

Additionally, please confirm the following:

What version of the Killer Performance Suite are you currently using? (You can find this in the app settings or under “About.”)
When was the last time you updated the Killer software and drivers?
In Task Manager → Details tab, do you see any “Killer” processes running? Does the Killer Performance Suite briefly appear and then close when you try to launch it?
Have you used any PC cleanup tools or registry cleaners recently?
Are you running the Killer app using the same user account that installed it?

If you have any other questions or need further assistance, feel free to reach out.

Best regards,

ok so both of the killer services are running in msc. i'll double check. they're called:

ok all FOUR killer services are running. see image

now lets see...

what version of killer performance suite am i using?

i like to keep all my software up to date.

version: version not listed in killer app. next best thing: killer version in Settings>Apps (see image)

version: 36.25.3250

Latest driver install date: 10/16/2025 from: I got an email from my manufacturer (Dell) stating there was a new update for your device. i installed the update yesterday and it just so happened to be a killer UWD driver.

Software/Driver updaters in use:

Norton Driver updater

Dell SupportAssist

Intel Driver & Support Assistant

i check all of these frequently and keep everything REALLY up to date. i use these to cross check each other, see who is lagging behind in driver updates. everything looks good at this time, except i just noticed this unique killer performance suite software anomaly. no devices detected? odd....

in task manager, yes killer apps are running automatically. however the killer performance suite app doesn't start upon computer boot up (it used to).

task manager -> details (see image)

this is the best i got for you, kent. thanks for your time.

Hi cam8528,

Thank you for answering my previous questions. To help further isolate the issue, please respond to the following questions below. It appears that you installed a Dell Universal Windows Driver (UWD) update on 10/16/2025, which updated your Killer drivers. However, your current Killer Performance Suite software (version 36.25.3250) maybe incompatible with the newer driver version.

What is the exact driver version of your Killer adapters?
(Right-click the adapter in Device Manager → Properties → Driver tab → Driver Version)
Did the Dell update change your driver version from what you had before 10/16?
Did you notice the “No Killer Adapters Connected” issue immediately after the 10/16 Dell driver update, or did it appear a few days later?

Please try the following steps:

Step 1: Update Killer Performance Suite

Download the latest Killer Performance Suite directly from Intel’s website.
Your current version (36.25.3250) may not be compatible with the updated UWD drivers.

Step 2: Driver Rollback Test (if updating doesn't resolve the issue)

In Device Manager, try rolling back the Killer driver to the previous version.
Check if the Performance Suite recognizes the adapters again.

Step 3: Clean Reinstall (if rollback also fails)

Uninstall the current Killer Performance Suite.
Download and install the latest version from Intel’s website.

You can find the latest Killer Performance Suite here: Intel® Killer™ Performance Suite

If you have any further questions or need additional assistance, please don’t hesitate to reach out.

Kent,

the problem with killer performance suite not detecting devices persists regardless of which driver is installed; the problem was noticed before the most recent driver installation. however i did check Event Viewer and noticed the following error

"The IntelTACD service failed to start due to the following error:
The system cannot find the file specified."

i do not know if this has anything to do with killer drivers/the killer app.

i will try uninstalling+reinstalling the killer app.

cam8528 · ‎10-20-2025

great, now i uninstalled killer performance driver suite and it says this when trying to reinstall. how incompetent

cam8528 · ‎10-20-2025

its annoying because to run the installer titled "KillerPerformanceSuite_40.25.905.1721_Win10-11x64.exe" it makes you first have to run appwiz.cpl and uninstall the software in the red box in the picture below:

ok so i uninstalled Killer Performance Driver Suite UWD from appwiz.cpl

then i was able to run the KillerPerformanceSuite_40.25.905.1721_Win10-11x64 installer.

after a reboot or two, and reinstalling Killer Intelligence Center from the microsoft store, i checked the app and the problem went away. it detected the device!

HOWEVER,

After another reboot, it no longer detects the device. i'm disappointed because for a second there, i thought reinstalling the killer package fixed the issue. however, no such luck.

as a side note, i would just say its really cumbersome and stupid that just to re-run the installer KillerPerformanceSuite_40.25.905.1721_Win10-11x64

it doesnt tell you that you need to open appwiz.cpl and uninstall the software in the red box above. it seems like the installer should just overwrite that software instead of making you do manual job like tinkering in appwiz.cpl

it should just run and reinstall the software automatically instead of presenting the user with the previous error message shown in the last post.

so i'm still stuck. please help!

cam8528 · ‎10-20-2025

of course immediately after making the previous post i checked back and it seemed to be working.

but then i went to install my manufacturer (Dell) update from Oct 16 that i got in my email, went through the appwiz.cpl conflict again, rebooted, installed the dell driver, rebooted, and now seems to be broken again. very very strange. it points to the dell driver.

Hi cam8528,

I hope you're doing well. After reviewing the issue, it appears that the behavior you're experiencing is being caused by the OEM application. In this case, we recommend reaching out directly to Support Home | Dell US as they will be best equipped to assist you further with troubleshooting and resolving the issue related to their software.

I will proceed to close this inquiry. Should you require further assistance or have additional questions, please feel free to submit a new request. Kindly note that this thread will no longer be monitored once closed.
