Key notes
The Suspect Arp Probe Failed error sometimes appears on the client-side Windows machines when the Wi-Fi or Ethernet connection drops suddenly. We have replicated the SuspectArpProbeFailed connection issue in our WR labs, and we have the tested solutions to fix it.
What is an ARP probe? The ARP Probe is a tool that checks a local network to validate that an IP address is unique. If it finds a duplicate IP address, it will look for a response from the original IP. In our case, the Suspect Arp Probe Failed error is caused by problematic Wi-Fi or Ethernet drivers from the endpoint.
How do I fix the Suspect ARP Probe Failed error?
Before going into more detailed fixes, let’s crosscheck some quick methods to investigate the problem further:
1. Run the Network and internet troubleshooter
For Windows 10, go to Settings>Update & Security>Troubleshoot>Additional troubleshooters, select Internet Connections, and click on Run the troubleshooter.
2. Update or roll back the Ethernet or Wi-Fi driver
If the solution doesn’t work, uninstall the driver and get the latest driver directly from the manufacturer’s website. This solution will work seamlessly on Windows 11 and 10.
If you’d like to simplify this whole process you can always rely on dedicated software such asOutbyte Driver Updater. This tool will scan your system, identify any outdated or broken drivers,and replace them with new up-to-date versions, in a matter of minutes.

3. Reset the network settings
After applying these solutions, the internet access will be restored, and if the device has any DNS issues, they will be fixed. To be on the safe side, you may also reset the router to make sure that the problem is not associated with thePC not getting the right settings from the router.
How do I fix Unexpected ARP Probe and ARP Announcement?
This is a very similar error that can be solved with the same solutions outlined above. However, the problem is caused by one of the computers from the network sending too many ARP packets.
So, the first thing you need to do is to isolate the system that is causing the overflow by disconnecting the terminals one by one and monitoring the network at the same time.
To summarize our guide, the Suspect ARP Probe Failed error is usually caused by problematic drivers for either the Ethernet or the Wi-Fi adapters. Running the Network and internet, troubleshooting, or fixing the drivers will eventually solve the problem.
You may also reset the network adapters to default factory settings if needed.
