How to fix 'Limited or no connectivity' on Windows Wi-Fi
When a Windows computer connects to Wi-Fi, it usually shows "limited or no connection", it is usually caused by the inability to obtain a valid IP address. You can troubleshoot it through the following steps: 1. Confirm that the router is working normally, restart the device and check the signal strength; 2. Run ipconfig/release and ipconfig/renew through the command prompt to refresh the IP address, or set it to automatically obtain the IP; 3. Update, disable/enable or reinstall the wireless network card driver; 4. Use Windows built-in network troubleshooting tools to detect problems. If the above method is invalid, it may be a hardware failure or router limitation. It is recommended to contact a professional to deal with it further.
