Solution on Windows, Linux and Android

22 mayo, 2021

You have your computer connected to the Internet, everything seems to be fine but you can’t navigate. It has happened to all of us on occasion, and there can be so many causes that it is often difficult to find a solution.

Let’s go over some of the checks we can perform when we believe that the Internet connection is fine but in no way can we navigate.

Try another device

Obviously, one of the first checks will be trying to connect from another device. If this works correctly, it is time to find out if it is a hardware or software error.

Before talking to the manufacturer to find out if there is a physical problem, it will be important to review all the connections and how the equipment with which we are having problems is configured.

What happens on the router?

The next thing we can do is physically check our router, checking that all cables are correctly connected. If everything seems fine, the next thing to do is look at the lights that appear.

If we have not saved the manual, we can search for it on the Internet (using a mobile device that does have a connection, obviously), in order to understand which lights should be on.

If, again, everything seems to be correct, the last thing we can do is reboot the router. Depending on the model, we find a power button on the back, or we can choose to unplug it and plug it in again.

Resorting to the classic “problem solver”

Whenever there is a problem on the network, we can use a functionality of the operating system that is responsible for carrying out a series of checks on our configuration.

Windows Network Diagnostic

On macOS We must go to Settings -> Network -> Assistant -> Diagnosis and let the system look for a solution. In Windows 10 we must follow these steps: go to the Network troubleshooter -> Identify and repair network problems in the list of results.

Android and iOS

In the case of Android, there is a very useful guide on this Google support page. The first thing they recommend is to try reboot device and if the problems persist, check if by deactivating Wi-Fi we can navigate with mobile data. If so, it would not be the device’s problem.

Apple also has a guide to troubleshooting connection issues on a iPhone, iPad or iPod touch. Again, the most important thing is to try restarting the device and see if we navigate with mobile data.

In both cases, we can try to forget the Wi-Fi network, entering the password again and reconnecting again.

Analyze installed software

An important step will be to verify if the problem is solved by installing another browser. If we identify that it is specific to an application, the best thing will be check extensions and programs that we have installed lately.

If you have an antivirus installed, it will be necessary perform an analysis and thus detect possible threats. If you do not use antivirus, you can use an antimalware to perform this check.

Finally, we can always resort to uninstalling the browser completely, download the latest version and reinstall it. Ideally, you should carry out a complete uninstall, deleting any configuration files left on the system.

Review DHCP and DNS settings

If after all these steps you still cannot navigate, the next thing to do is check if we have a fixed IP configured. The best thing to do is to make sure that the network settings are set to automatic.

On Windows 7, Windows 8.1 and Windows 10 We will have to follow the steps detailed on this Microsoft support page. MacOS users can check out a simple guide on this Apple support page.

Ubuntu IP

In the case of LinuxIf we want to avoid using the Terminal and do it from the graphical interface, we will simply have to go to System -> Preferences -> Network connections. There we will click on “Edit” and in “IPv4 Settings” select “Automatic Method (DHCP).

After applying the changes, try to reconnect again. If you cannot navigate, it will be time to continue trying possible solutions.

By following these steps you can improve the connection with your PC by configuring the Wi-Fi adapter

Change authentication and encryption

it’s possible the type of security of our router is incompatible with the device with which we are having problems. If you are trying to connect via Wi-Fi, try changing the authentication mode and encryption.

Surely, by default your router will be configured in WPA-PSK / WPA2-PSK. You can try changing it to WEP or open, although it is only recommended to do it momentarily for this test.

Another possible option may be change the WPA encryption mode. By default AES will come, but we can try to change it to TKIP. If you have made this change, it will be necessary to disconnect and reconnect to the network.

If we have done all these checks and we still cannot navigate, the last assets we have left is to call our Internet provider, format the equipment and speak directly with the manufacturer.
