1. The reason why the laptop is limited after connecting to wifi.
1. IP address conflict.
When the IP address conflict occurs after the laptop is connected to WiFi, you can solve it by the following methods: right-click the network icon in the lower right corner of the desktop, select "Open Network and Sharing Center", select "Local Connection" in the pop-up window, and then click "Properties", select "TCP IP Protocol Version 4" in the pop-up property window, and set the IP address and DNS address to be obtained automatically. If that doesn't solve the problem, you can try disabling the local connection and re-entering the wifi password to connect.
2. Network setting problems.
If you have network setup issues after connecting your laptop to WiFi, it may be because the WiFi network does not provide Internet service. In this case, you can use your mobile phone or other device to connect to that wifi network and test whether you can access the Internet. If other devices also can't access the internet, you can try contacting your network administrator to resolve the issue.
3. Router setting problems.
When the laptop is restricted after connecting to wifi, it may be because the router is not set up correctly. For example, if the router's firewall is not set up correctly, it may cause the laptop to not be able to access the Internet properly. At this point, you can try to modify the router's firewall settings, or reset the router and reset the network parameters.
Second, the solution to the limitation of the laptop after connecting to wifi.
1. Check the IP address and DNS settings.
When it comes to resolving IP address conflicts, you first need to check if your laptop's IP address and DNS settings are correct. You can open the "Network and Sharing Center" in the control panel, then click "Local Connections", double-click "Internet Protocol Version 4" in the properties window, and set the IP address and DNS address to be obtained automatically. If the IP address and DNS address have been manually assigned, you can try to obtain them automatically.
2. Disable the local connection and reconnect.
When fixing network settings issues, you can try disabling the local connection and reconnecting to the wifi network. Here's how: right-click the network icon in the lower right corner of the desktop, select "Open Network and Sharing Center", select "Local Connection" in the pop-up window, then click the "Disable" button, wait for a few seconds and then click the "Enable" button to reconnect to the WiFi network. If the problem persists, you can try resetting the router and resetting the network parameters.
3. Modify router settings and reset network parameters.
To resolve router settings, you can try to modify your router's firewall settings, or reset your router and reset your network parameters. For example, enter the IP address and username and password of the router in the browser to log in to the router management interface, and then click "Wireless" or "Wireless Security" to modify the firewall settings or reset the network parameters in the pop-up window. If the problem persists, you can try replacing it with a brand new router and resetting the network parameters.
3. Summary. There are many reasons why your laptop may be restricted after connecting to WiFi, including IP address conflicts, network setup issues, router setup issues, and more. Workarounds include checking IP address and DNS settings, disabling local connections and reconnecting, modifying router settings and resetting network parameters, etc. If none of the above methods solve the problem, you can try to contact a professional technician to repair or replace the network device.
