Connection problems are quite frequent with many computers. With these steps you can detect faults in your network and fix them easily and quickly.
One of the most frequent problems we encounter when using a computer is that connection does not work. At first glance, it seems that everything should be fine, but the computer does not connect to the Internet. And although many operating systems have a self-diagnosis program for network failures, the truth is that many times it does not work well.
By following these 7 steps, you can easily detect faults in your network. And with any luck, you can also fix it.
Make sure the problem is yours
The first step may seem self-evident, but it is important to keep in mind. Maybe it’s not your connection that is failing but the page you are trying to access. To check it, try to connect to another website.
You could also have a problem with a specific page Although that page is not every. If you want to make sure that the problem is not yours, you can use isup.me, a service that tells you if a website is working or not.
Restart the router and computer
The first solution to consider, although many times people forget it. The connection problem can be caused by an error in the router or computer cache, and clearing the entire cache is as easy as restart the device. When rebooting the router, leave it one minute off to make sure the cache gets cleared.
After restarting, check if the connection works. If it does not work on any device, the problem is with your operator. But if it is a single device that has no connection, you can try to solve the problem in other ways.
Check that the device can receive connection
Before you start doing complicated tests, you should make sure that your device has the connection settings activated. If you are trying to connect via WiFi, make sure you have WiFi enabled. Many computers have a button on the keyboard to turn it on and off, and you may have accidentally pressed it.
If you are trying to connect by cable, make sure that the cable is correctly connected to both the router and the computer.
Test the network diagnostic system
Windows has integrated a network diagnostic system who can help you. To activate it, just right-click the connection icon and select troubleshoot. Normally, network diagnostics is not capable of troubleshooting, but sometimes it does.
In any case, what the diagnostic system will probably offer you is precisely that: a diagnosis. If it gives you the name of an error or problem, write it down, because it can help you if you contact the technical service of your operator.
Make sure you use a valid IP
You have already verified that you have a connection problem, that it does not depend on the cache of any device and that it is not a problem of your operator. It is a problem that Windows cannot solve by itself. So now you’re going to have to get serious about solving the problem.
Open the Network and Sharing Center (right click on the connection icon) and click on the name of your network. In the window that will be displayed, select properties and then double click on Internet Protocol version 4.
There, select to both obtain an IP address automatically and obtain the DNS server address automatically. Then follow the same process with Internet Protocol version 6.
Now, to verify that the IP that your computer receives is valid, open the cmd and type the following command:
Next, check the IP that your computer receives in the section Ethernet Ethernet adapter if you are connected by cable or WiFi wireless LAN adapter if you are connected via WiFi. If the IPv4 address starts with 169, it is not valid. To fix it, enter the following commands:
ipconfig / release
ipconfig / renew
If the IP you receive still starts at 169, try connecting via cable if you are not. If you have a connection when connecting by cable, the problem is with your router.
Find at what exact point the problem happens
In the event that your computer receives a valid IP (any that does not start with 169), but you still do not have a connection, the problem occurs at some point between your router and the Internet. To locate the exact moment when the problem occurs, you have to resort to the cmd again, and type the following command:
By using that command, you will get in response all the steps the router follows to connect to google.es. Of course, you can use any other website. You can also see in which step the error occurs. If the error is one of the first steps, the failure is probably from your local network.
Contact your operator and wait
Once you have tried all the solutions that are in your hand, if nothing has worked, the best thing you can do is contact your operator. Once you leave the problem to them, the best thing you can do is wait for them to fix it. Probably the problem is a drop in the service in your geographical area.
