Many users experience the "Wi-Fi IP Configuration Error", which blocks network access due to IP conflicts or incorrect settings. This article provides common solutions to quickly resolve the issue and restore your connection.

Method 1: Restart the Router and Device

Turn off the router, wait for 30 seconds, and then restart it.

On your device, disconnect from Wi-Fi and restart the device.

After rebooting, reconnect to the Wi-Fi and check if the problem is resolved.

Method 2: Update Network Drivers

Outdated network drivers can be a common cause of Wi-Fi IP configuration errors. Ensuring your wireless network driver is up to date can improve the stability of your network connection. It is recommended to use Driver Talent for automatic driver detection and updates, which saves time and avoids installing incorrect drivers.

Download Driver Talent

Click the download button to get the latest version of Driver Talent, install it, and open the software, then click "Scan".
After scanning, the software will display which drivers need to be installed or updated. Find the network driver in the results list and click "Download".

Method 3: Flush the DNS Cache

Press Win + R to open the "Run" dialog box, type "cmd", and press Enter to open Command Prompt.

In the Command Prompt window, type the following command and press Enter: ipconfig /flushdns

Close the Command Prompt and try reconnecting to Wi-Fi to see if the problem is resolved.

Method 4: Automatically Obtain an IP Address

Click "Network and Sharing Center" and select "Change adapter settings".

Right-click the connected network and select "Properties".

In the "Properties" window, double-click "Internet Protocol Version 4 (TCP/IPv4)".

In the pop-up window, ensure "Obtain an IP address automatically" and "Obtain DNS server address automatically" are checked.

Wait a few seconds, then right-click the adapter again and select "Enable device".

Once enabled, reconnect to the Wi-Fi and check if the issue is resolved.

Method 7: Check Router Settings

Open a browser and type the router's IP address into the address bar, usually 192.168.1.1 or 192.168.0.1 (you can check the label on the bottom of the router for the exact address).
Enter the administrator username and password (usually found on the router's label, e.g., admin/admin; if modified, enter your updated credentials).
After logging into the router settings interface, locate the DHCP settings (usually under "LAN Settings" or "Network Settings").
Ensure the DHCP server is enabled. If not, check the "Enable DHCP Server" option and save the changes.
Restart the router, reconnect to the Wi-Fi, and check if the issue is resolved.
