wifi connected but no internet only on one device

It's frustrating when your device can't access the internet, even though it's connected to the WiFi network. This issue can be caused by a variety of factors.

The WiFi connection settings on your device might be incorrect, such as a wrong IP address or subnet mask. This is a common problem that can be easily fixed by restarting your router.

A faulty WiFi adapter on your device can also prevent internet access. This can be due to a malfunctioning adapter or a loose connection.

Have you tried switching to a different WiFi network or checking your internet service provider's status to see if there's an outage in your area?

If you're experiencing WiFi connected but no internet on a mobile phone, try restarting your phone and router, as these are the basic steps you should always do first.

A DNS issue might be the problem, and setting a fixed DNS server, such as 1.1.1.1 / 1.0.0.1, can solve this.

In some cases, the issue is related to the device's IP address not matching the expected subnet. Check your IP address on your laptop and ensure it's what you expect.

If the issue persists, try connecting your laptop via cable, as this can "force" the communication with the DHCP server and refresh the device's information in the server's cache.

A mesh network can sometimes cause issues with internet access on specific devices. In one case, a Windows 11 Laptop was unable to access the internet on a mesh WiFi network, but was able to connect to the main WiFi network.

The issue might be related to the device not being visible in the Google Home app, or it might be a problem with the device's IP address not matching the expected subnet.

Ensure that the router and modem are powered on and functioning correctly to prevent connectivity issues.

If you're using a mobile hotspot to connect your computer to Wi-Fi, it's worth checking if your mobile data is turned off or exhausted. This is because your mobile data is the source of internet access for your hotspot.

If your mobile data is turned off, simply turning it on should resolve the issue. If it's exhausted, you'll need to refill your data plan to regain internet access.

If you're using a mesh network, it's possible that the issue is caused by a mismatch between the subnet settings on your device and the router. Check your IP address to see if it matches what you expect.

If not, you may need to change your laptop settings or the router settings to match. Remember to save the changes, as forgetting to do so can cause the issue to persist.

Connecting your device via cable can also help resolve the issue, as it ensures communication with the DHCP server and assigns an appropriate IP address.

Unfortunately, this solution may not be permanent, and you may need to reconnect your device via cable periodically to maintain access to the internet.

Network problems can be frustrating, especially when only one device is affected. Restarting your router or modem is a fundamental troubleshooting step that can resolve many network connectivity issues, including the "connected to WiFi but no internet" problem.

If multiple devices have the problem, it's likely related to a problem with your router or modem, wireless network, or ISP. However, if only a single device can't connect to the internet, the problem might be related to a corrupt DNS cache, wrong DNS server configured, or wireless adapter related issue.

If you're having trouble connecting to the internet on your mobile phone, try setting a fixed DNS server, as it can solve DNS issues. Also, make sure to restart your phone and router first, as these are the basic steps to always do first.

You can try setting a fixed DNS server to solve this problem.

If you're experiencing issues on a single device, it's possible that the problem is related to a corrupt DNS cache, wrong DNS server configured, wrong or outdated network information, anti-virus or firewall causing problems, or a wireless adapter related issue.

If multiple devices are experiencing issues, the problem might be related to the router, modem, or wireless network.

Try testing your network with a network cable first to rule out any issues with your wireless network.

If you're connected to a wireless network of a repeater and experiencing the error "WiFi connected but no Internet", the network connection between the repeater and your router is likely lost.

Try resetting your repeater or moving the base station closer to your router.

Here are some possible causes of the "WiFi connected but no Internet" error:

Network Congestion is a common issue that can slow down your internet speeds significantly.

It happens when too many devices are using the same network simultaneously, consuming the available bandwidth and causing a bottleneck.

This is particularly common in households with multiple internet-connected devices.

During peak usage hours, such as when everyone is streaming or gaming at the same time, congestion can become even more severe.

In extreme cases, network congestion can prevent access to online services altogether.

Network congestion is a major problem that can be caused by too many devices using the same network.

If you're experiencing the frustrating issue of being connected to WiFi but having no internet access on one device, there are several potential causes to investigate.

First, try restarting your router and device. This is a basic step, but it's often overlooked and can resolve the issue.

If restarting doesn't work, the problem might be related to a DNS issue. Setting a fixed DNS server can solve this problem, as mentioned in Example 2.

A corrupt DNS cache can also cause this issue. You can try flushing your DNS cache to see if it resolves the problem.

Another possible cause is a problem with your wireless network. Try testing your network with a network cable to see if the issue persists.

If only one device is affected, it's likely related to a specific issue with that device, such as a corrupt DNS cache, wrong DNS server configured, wrong or outdated network information, anti-virus or firewall causing problems, or a wireless adapter related issue.

Here are the possible causes for a single device:

If you're experiencing issues with a mesh network, it's possible that the problem is related to the device's IP address not matching the subnet expected by the router. You can try checking your laptop's IP address and adjusting it if necessary.

Connecting via cable can also help resolve the issue by forcing the communication with the DHCP server and refreshing the device's information in the server's cache.

However, if the solution is not permanent and you have to connect the device by cable again every few days, it's possible that the fix is not a long-term solution.
