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 the router to work 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.

A "limited or no connection" prompt appears when connecting to Wi-Fi, which usually means that the device cannot obtain a valid network address from the router, resulting in the inability to access the Internet normally. This problem is common in network configuration errors, IP conflicts, driver problems, etc. Below are some practical troubleshooting and solutions to help you quickly solve this annoying problem.

Check whether the basic connection is normal

First make sure your router is working properly. Check whether other devices can connect to the same Wi-Fi and access the Internet normally. If other devices also have problems, it may be that there is a problem with the router itself, such as network disconnection, restarting, setting changes, etc.

If you only have problems with your computer, then continue to check:

• Try reconnecting Wi-Fi once
• Turn off and turn on the wireless function (can be a physical switch or shortcut key)
• Get close to the router to test the signal strength and eliminate distance or obstacle interference

Sometimes it is just a temporary glitch, and it can be solved by restarting the device.

Release and renew IP address

Windows uses dynamically assigned IP addresses by default, and if IP acquisition fails, it will display "Limited or No Connection". You can manually refresh the IP to fix:

1. Open a command prompt (run as administrator)
2. Enter the following command and press Enter:

    ipconfig /release

3. Enter again:

    ipconfig /renew

If you see the prompt "Cannot contact the DHCP server", it means that the router may not respond. At this time, you can try restarting the router.

In addition, you can also consider setting the IP to automatically obtain (make sure it is not manually fixed):

• Control Panel > Network and Sharing Center > Change Adapter Settings
• Right-click the current Wi-Fi connection > Properties > Double-click Internet Protocol Version 4 (IPv4)
• Select "Automatically obtain IP address" and "Automatically obtain DNS server address"

Update or reset network drivers

Sometimes problems with wireless network card drivers can also lead to abnormal connections. You can try the following:

• Open Device Manager (right-click Start Menu > Device Manager)
• Find "Network Adapter", expand and find your wireless network card
• Right-click it and select "Update Driver"
• If you have the option "disable" and then "enable", you can also try it

If the update is not successful, you can download the latest driver installation on the official website. Some brands of laptops (such as Lenovo and Dell) can directly search for models and download corresponding drivers on the support page.

If it still doesn't work, you can try reinstalling the driver or restoring the default settings.

Use the network troubleshooting tool

Windows's own network troubleshooting can automatically detect some common problems and try to fix them. Although not always working, it's worth a try:

• Settings > Network and Internet > Status
• Scroll to the bottom and click "Network Troubleshooting"
• Follow the prompts to run

If the problem is found but cannot be automatically fixed, the system will give a prompt, and you can further deal with it according to the prompt.

Basically these common solutions. In most cases, a step-by-step investigation can solve the problem. If you try all of them but haven't gotten it, it may be a hardware problem (such as a network card damaged), or the router has set restrictions such as MAC address filtering. It is recommended to find a professional to assist in the inspection at this time.
