Why can't I access the Internet even though my wifi is connected?

Reasons why wifi is connected and cannot access the Internet: 1. Weak WiFi signal; 2. IP address conflict; 3. DNS server problem; 4. Router failure; 5. Network provider problem; 6. WiFi network itself Problems; 7. Router problems; 8. Equipment network setting problems; 9. Signal interference or obstacles; 10. Equipment problems. Detailed introduction: 1. The WiFi signal is weak. The strength of the WiFi signal directly affects the stability and speed of the network. If the connected WiFi signal is weak, it may cause the network connection to be unstable or unable to access the Internet, etc.

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

When you connect to a WiFi network and find that you cannot access the Internet, there may be the following reasons:

1. The WiFi signal is weak: The strength of the WiFi signal directly affects Network stability and speed. If the WiFi signal you are connected to is weak, it may cause the network connection to be unstable or unable to access the Internet. At this point, you can try moving closer to the router or using a signal booster to enhance signal coverage.

2. IP address conflict: Each device has a unique IP address in the network. If multiple devices use the same IP address, it will cause network conflicts and prevent you from accessing the Internet. At this point, you can check your device's IP address settings to make sure each device has a different IP address.

3. DNS server problem: DNS server is the key to resolve domain names into IP addresses. If your device cannot properly connect to the DNS server, it will not be able to access the Internet. At this time, you can manually set the DNS server address, or contact the network provider to find out whether there is a DNS server failure.

4. Router failure: The router is the bridge between the connecting device and the Internet. If your router fails, you will be unable to access the Internet. At this point, you can try to restart the router and check whether there is obvious physical damage to the router, or check whether the network cable is firmly connected. If all the lights on the router are off, you should consider reporting it for repair.

5. Network provider problems: Sometimes, the inability to access the Internet is caused by problems with the network provider. For example, the supplier's server fails, the line is repaired, or there is network maintenance and other reasons. At this time, you can contact the network provider to find out whether there is a network failure. If so, wait patiently for the provider to resolve it.

6. Problems with the WiFi network itself: It may be caused by broadband arrears or other network problems. You can try connecting to other WiFi first to see if you can access the Internet normally. If there is no other WiFi to connect to, you can ask someone around you to turn on the hotspot, and then try to connect to see if it works normally.

7. Router problem: It may be caused by overheating, damage of the router or network cable connection problem. You can try to restart the router, check whether there is obvious physical damage to the router, or check whether the network cable is firmly connected.

8. Device network setting problems: Sometimes, the device's network settings may cause connection problems. You can try modifying your device's network settings, such as setting it to a static IP or DHCP.

9. Signal interference or obstacles: Electrical appliances or other equipment in the home may interfere with WiFi signals. Make sure your router is far away from these sources of interference and that there aren't too many obstructions within your home's WiFi signal coverage.

10. Equipment problems: Sometimes, the problem may lie with the equipment itself. You can try to use another device to connect to the same WiFi to see if you can access the Internet normally. If other devices cannot access the Internet, the problem may be with the WiFi or network; if other devices can access the Internet normally, the problem may be with the original device.

In short, when you connect to a WiFi network and find that you cannot access the Internet, you can troubleshoot and handle it from the above aspects. If the problem persists, it is recommended to contact professional technical support personnel for further investigation and processing.
