Killer network driver causes high ping — Fix on Windows 11 (2026)
If you're getting "Killer network driver causes high ping" on Windows, the cause is almost always the Killer / Rivet network driver — either a buggy release, a leftover from an older install, or a Windows Update / vendor driver fighting for the same device. The clean-install path below fixes 90% of cases.

Likely causes
- ▸Killer Network Manager prioritizing the wrong traffic
- ▸Buggy Killer driver branch (a known issue on multiple revisions)
- ▸Intel + Killer hybrid driver conflict

How to fix it — step by step
- 01
Update the Killer / Rivet network driver from the vendor
Skip Windows Update for this — go directly to the Killer / Rivet site and download the latest network driver for your exact model. Use the "Custom (Advanced) → Perform a clean installation" option if the installer offers it.
- 02
If a clean update doesn't fix it, do a real clean reinstall with Killer Network Suite Uninstaller
Killer Network Suite Uninstaller removes every trace of the previous driver — leftover registry keys, services, files. Boot into Safe Mode, run Killer Network Suite Uninstaller, choose "Clean and do NOT restart", then install the fresh driver immediately after the reboot.
- 03
Roll back to the previous driver version
Sometimes the newest driver is the problem.
Device Manager → Killer / Rivet Network → Properties → Driver → Roll Back Driver. If the button is greyed out, manually install a previous version from the vendor's driver archive. - 04
Check for a Windows error code on the device
Open
Device Manager, find the Killer / Rivet network device and read the Properties → General → Device status message. Code 43 means the device reported a hardware error; Code 28 means no driver is installed; Code 10 usually means a driver/firmware mismatch. - 05
Disable Fast Startup
Windows Fast Startup keeps the kernel in a saved state across reboots, which sometimes leaves driver state inconsistent.
Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable → uncheck "Turn on fast startup". - 06
Test the hardware in another machine or another slot
If every clean reinstall fails, isolate the hardware. A failing network device or a flaky PCIe / USB slot can look exactly like a driver bug. Swap to a different port — or, for GPUs, a different slot — before assuming the driver is at fault.
