What Causes “An Unexpected Error Occurred” Ethernet Problem in Windows?
The “An unexpected error occurred” message can be caused by a variety of things, including corrupted files and drivers or outdated software. It can also be caused by a virus or malware on your system.
How Do I Fix “An Unexpected Error Occurred” Ethernet Problem?
The first step you should take is to run a virus scan on your system. If the issue is caused by a virus or malware, the virus scan should detect it and allow you to remove it from your system.
If the virus scan does not find any malware or viruses, then you’ll want to check for corrupted files or drivers. To do this, open Device Manager on your computer and look for any devices with a yellow exclamation point next to them. If you find any, then right-click on the device and select “Update Driver.” This should download the updated driver for your device and fix any corrupted files or drivers.
If updating the driver does not work, then you can try reinstalling Ethernet drivers from your computer manufacturer’s website. Finally, if all else fails, you can try uninstalling and reinstalling your Ethernet adapter.
Check you’re connected to the right network
If you’re still experiencing the issue, it could be because you’ve connected to the wrong network. To check this, open your Network Connections window and make sure that the connection you are using is marked as “public” or “private.” If it is set to public, then switch it to private and try connecting again.
Update your drivers and software
Sometimes, an unexpected error can be caused by outdated drivers or software. To update your drivers and software, open your Device Manager window and look for any devices with a yellow exclamation point next to them. If you find any, then right-click on the device and select “Update Driver” to download the updated driver for your device. You can also check for Windows updates by going to the Start menu and selecting “Check for Updates.”
Restart your router and modem
If you’re still experiencing the issue, it could be because your router and modem need to be restarted. To do this, unplug both devices from their power sources for at least 30 seconds. Then plug them back in and wait for all the lights to come on before trying to connect again.
Reset your IP address
Sometimes, an unexpected error can be caused by a corrupted IP address. To reset your IP address, open the Command Prompt window and typeipconfig /release” followed by “ipconfig /renew” then hit enter.
