Why is my Wi-Fi on but not working?

Troubleshooting Wi-Fi Connectivity Issues

It’s frustrating when your Wi-Fi is connected but the internet is inaccessible. The problem usually lies within the device itself rather than the Wi-Fi network. Here are some common causes and solutions to help you troubleshoot:

1. Incorrect Network Settings:

• Check if the device is connected to the correct network.
• Make sure the network password is entered correctly.
• Verify that the device’s IP address and DNS settings are set to “Obtain automatically” or are manually configured correctly.

2. Wi-Fi Adapter Issues:

• Ensure that the Wi-Fi adapter on the device is enabled.
• Try disabling and then re-enabling the Wi-Fi adapter.
• Check the device’s Device Manager to see if the Wi-Fi adapter is working properly.

3. Outdated or Corrupted Drivers:

• Outdated or corrupted Wi-Fi drivers can cause connectivity problems.
• Visit the manufacturer’s website to download and install the latest drivers for your Wi-Fi adapter.

4. Corrupted DNS Cache:

• The Domain Name System (DNS) cache stores website addresses and their corresponding IP addresses. If it becomes corrupted, it can disrupt internet access.
• To clear the DNS cache, open the Command Prompt (as administrator) and type “ipconfig /flushdns.”

5. Firewall or Antivirus Interference:

• Some firewalls or antivirus software may block internet access.
• Temporarily disable these programs to see if that resolves the issue. If it does, add an exception for your Wi-Fi network in the security settings.

6. Network Congestion:

• If multiple devices are connected to the same Wi-Fi network, it can lead to congestion and slow or intermittent internet access.
• Disconnect unnecessary devices or consider upgrading to a faster Wi-Fi router.

7. Physical Obstacles:

• Objects such as walls, furniture, and metal can interfere with Wi-Fi signals.
• Reposition your device to a location with a stronger Wi-Fi signal.

8. Power Cycling:

• Restarting both the device and the Wi-Fi router can resolve many connectivity issues.
• Unplug the power cords from the devices, wait a few minutes, and then plug them back in.

If you have tried all of these steps and still cannot access the internet, the issue may be with the Wi-Fi network itself. In this case, contact your internet service provider (ISP) for assistance.
