The reason why WLAN is connected but cannot access the Internet

When WLAN is connected but cannot access the Internet, it may be caused by the following reasons:

1. IP Address Conflict

• If your device has been assigned the same IP address as another device on the network, it will cause an IP address conflict, which will interfere with Internet connection.

2. DNS setting error

• The device requires correct DNS settings to resolve domain names to IP addresses. Incorrect DNS settings can result in inability to access the Internet.

3. Gateway Issues

• Network gateways are responsible for routing data from your device to the Internet. If the gateway fails, you will not be able to access the Internet.

4. Firewall or security software

• Firewalls and security software sometimes prevent devices from connecting to the Internet. Check your firewall settings to make sure they allow your device to access the Internet.

5. Router firmware is out of date

• #If your router's firmware is out of date, it may not be able to communicate properly with your device. Update the router's firmware to resolve this issue.

6. Physical connection issues

• Check the physical connection between the device and the router. Make sure the cables are securely connected and not damaged.

7. Network Congestion

• If the network is congested, it may cause the device to be unable to connect to the Internet. Try connecting at different times or using a different network.

8. Service Provider Issues

• Your Internet Service Provider (ISP) may be experiencing a glitch or outage. Contact your ISP to confirm if there are any issues.
