Refreshing the IP settings sometimes help you fix most Internet connection errors, including the Windows Has Detected An IP Address Conflict error. Follow below guide to do it:
- Right-click Start icon (or hit the ‘Windows + X’ shortcut on your keyboard) and select Command Prompt (Admin), select Yes when you’re asked for administrator permission. If you can not find it in ‘Windows + X’ menu in Windows 10, try to put it back;

Some users confuse between restarting and resetting. Remember, restarting is very different from resetting a router. Perform a restarting is far less extreme than a resetting but it will help to fix most problems, including the Windows Has Detected An IP Address Conflict error.
Steps to restart a router:
- Typically, you’ll see at least two buttons on your router. One is a power button, other is labeled Reset, it does not do the same thing. In case you can not find a power button, try to reach the power outlet which your router is plugged into;
- Use the power button to turn your router off in case you found it. Whether you found the power button to turn off the router or not, unplug the router from outlet power;
- You should unplug all other access point devices on the network if available or modem in case your router is connected to it;
- From the moment you finish step 3, wait at least 30 seconds before the move to the next steps.
- In this final step, you need to plug everything back in, then use the power button to turn it on. The router needs 30-60 seconds to establish a stable connection with your ISP. Your computer should automatically connect to the router. If it doesn’t, open the WiFi setting and connect again.
Method 3: Restart your network adapter
The problem may come from your network adapter too, try to disable then enable it to see if the problem is fixed. To do this:
