▷ How to fix unavailable gateway and other frequent errors

Almost all of us have Internet at home, and on many occasions we suffer from errors such as the gateway is not available, an unidentified network or the ethernet cable is not connected in Windows 10. For this reason we have proposed to propose the maximum amount of useful solutions to solve our connection problems.

Sometimes the solution is as simple as rebooting the router or our own equipment, and other times the problem results in more serious results such as having to purchase a new router or otherwise, a new network card. It is not common that the errors we get are due to hardware failures, since these computers are generally quite reliable and relatively easy to manage.

Gateway error not available

The reason for this error may be due to various circumstances, including:

• Our router is updating: it may be that at a certain moment the firmware of our router is updated and temporarily we get errors like this. The router is turned off: normally another message will appear such as "the network cable is not connected", although it is also possible to see the one in question. Firmware or port failure: precisely this error is not one to let pass. It is not very common to obtain it, so it may be due perfectly to an error in the firmware of our router or even the malfunction of the connection port Error in the configuration of the adapter: on the part of our equipment, it may also be due to a adapter configuration error.

Solution 1: Restart router and / or computer

Well, even if it seems silly, the first thing we would have to do is reboot, first the router and then, if the problem persists, the equipment.

Not having the available gateway, is indicative that the connection between the equipment and the router is not correct, since the gateway is precisely the IP of our router and is necessary to connect our computer to the Internet to through it.

By restarting both devices, we will, on the one hand, reload the router's firmware, thereby solving possible bugs that may have occurred during its operation, and on the other hand, restart our network adapter so that it tries to obtain a new IP from the server. DHCP of the router.

Solution 2: Change the connection port or try another computer

Another mandatory measure before we start testing configurations, is of course, trying to change the Ethernet cable port, in order to verify that the problem persists. Another interesting practice may be to try to connect other equipment, either via Wi-Fi or via cable.

• If we continue with the same problem, on other ports or other types of connections, it is certain that the problem is in our router. If, on the contrary, we have been able to obtain an IP address correctly without error and with access to the Internet, it will mean that the error is in our own team.

Solution 3: Problems on our computer: troubleshooter

Well, if we have followed the procedure in the previous section, we will have identified that the problem can be found in our specific team. We are going to test with the Windows troubleshooter to see if it is able to easily fix the problem.

We go to the right area of ​​the taskbar to right-click on the network icon. Then click on " troubleshoot"

Now we will follow the steps of the wizard, which will vary depending on the problem you have detected. Sometimes this assistant is able to solve the problems that we have.

In addition to this, Windows has a few commands to force the appearance of some troubleshooters that may do the task we need.

We are going to go to " Start " and we are going to type " CMD " to click on the search result " Command Prompt ". We will place these commands one by one and press Enter every time we put one:

msdt.exe -id NetworkDiagnosticsNetworkAdapter

msdt.exe -id NetworkDiagnosticsWeb

msdt.exe -id NetworkDiagnosticsInbound

Solution 4: Problems on our computer: manually restart the controller

What we are going to do is try to restart our connection using this procedure:

We are going to go to " Start " and we are going to type " CMD " to right click on the search result " Command Prompt " and we will choose the option " Run as administrator ". In this way we will open the Windows command terminal.

Now we are going to put in order the following commands:

ipconfig / release ipconfig / flushdns ipconfig / registerdns ipconfir / renew

In this way the network adapter will have requested all the network information from the router again.

Now we try again to connect to the Internet.

Solution 4: Problems on our computer: create a new network adapter

If it still shows us that the gateway is not available, or the unidentified network message, we are going to carry out a slightly more extreme process and reinstall our internet controller from our computer from scratch.

We are going to place ourselves on the start button, and we are going to press on it with the right button. We will choose the option " Device Manager"

A window will appear with a list of devices in which we will have to search in the upper area " Network adapters ". Click on the arrow to display the information and then we will locate the brand and model of our network card. Right click on it, and choose the option " Uninstall the device"

The other items on the list will not matter to us, the only important one is our adapter. It will have disappeared and now a red "x" will appear on the network icon in the taskbar.

Don't panic, let's go to the " Action " option within the device manager, and click on " Search for hardware changes ".

Our network card will immediately reappear in the directory and a new adapter will be configured to reestablish the connection.

If in our case we have an external network adapter or through an expansion card, we may also need the installation of the corresponding drivers to get the controller to work correctly. Knowing the brand and model of the device, we can go to the manufacturer's page to download them.

Solution 5: The network cable is not connected

Now we are out of our team, because already, in principle we have carried out all the checks within it. At this point, the error may be due to a bad network cable. The cable crimp may be broken or not making good contact.

In this case, we only have to buy a cable, compare another, or test whether the router gives us Internet access through Wi-Fi.

Solution 4: Router problem

As we have said, it is possible that the router is being updated, we will notice it right away if we access it, if we see its lights turning off even though it is connected to power, or simply because it has a light dedicated exclusively to notify that the system is updated. In this case, we must NOT restart the router, we must wait for the procedure to finish.

Sometimes it happens that due to sudden power cuts the firmware configuration gets corrupted or the update fails. In this case, what we will have to do is a complete reset to the router in order to restore the factory settings of the equipment.

Normally, most routers, after this procedure, automatically connect to the Internet and assign an IP address to the computers connected to them. On other occasions we will have to be the ones to carry out a small configuration through an assistant if we enter the team.

Initial configuration of a router after resetting

The first thing we will have to do in this case, is obtain the IP address of the router or gateway. For this we are going to go to " start " and write " CMD " to open " command prompt"

Now we will have to place the command " ipconfig " and press Enter. We look at the IP address that is located on the " Default Gateway " line.

We must take this and place it in a web browser to access the router. Immediately a page will appear where we will be asked for a username and password, or we will directly enter the assistant.

The configuration process will always be quite simple and intuitive, although if you want to see some examples, we recommend you take a look at these tutorials:

Performing the procedure, all the Internet connection in your house would be fully restored and you should not have to connect.

If you don't feel like doing all this, the best thing to do is to talk to your network provider to see what solutions they offer you.

Final solution: try another router or contact the internet provider

We are paying for something, if we cannot solve the problem with the previously proposed methods, it means that we have to call the Internet provider and explain our problem. We will detail the problem, and if it affects only our equipment or anyone that connects to the router.

These methods are the ones we recommend to follow if we find various errors with our connection: gateway not available, network cable is disconnected or network not identified. In general, everything will have similar procedures as the ones we have proposed.
