If your internet network is having trouble connecting, here are the steps you should try.
In all kinds of computer problems you may encounter, network connectivity problems are one of the worst problems. Even if your computer can work offline taking most of the time, being disconnected from the internet is no fun thing when you are at work. Worse, when you lose your network connection, you cannot research suggestions for fixing your problems through instructions from the internet.
If you are in such a case, you can quickly consult the suggestions that help resolve most network connectivity problems, especially those that are quite simple. As follows.
1. Check that other devices have the same connection and restart the network device
First, check the other surrounding devices with the same internet connection and check if they have the same problem with you. If so, this is a common connection problem and the simple thing you need to do now is to restart the network device.
It can be said, one of the simplest and easiest ways to fix the problem for every technology device is to reboot. In addition, you should also restart your computer and access the network again to check.
In most cases, restarting will be able to fix many system errors of the device that is currently suspended, unresponsive or overloaded. If you still can’t access the network, try another computer or another mobile device nearby. If you still cannot access the network, you can now narrow down to whether that errors occur from network devices or from ISP network connections.
In case other computers or mobile devices can access the network, you can determine the error appears on your computer only. At that time, you can try a solution using virus scanning software to check if the computer is infected with virus or malware. Or you can use another browser to open some web pages.
2. Check the physical connection
If the network problem is still not fixed after restarting, start going into the physical examination steps. Specifically, if you are using an Ethernet cable to connect the computer to the router, check to make sure it is firmly attached or not removed by someone.
During the testing process, take a look at the status of the network devices. Is the signal light on the router and modem blinking green as usual? If no lights are lit after booting, the device may have “died”. If the signal light turns red, or the power indicator light is light but there is no connection, it may be a problem for the line from your ISP.
If your laptop is equipped with a physical switch to turn on / off Wi-Fi wireless connection mode (the location of this button depends on the model), make sure it is not switched to OFF.
3. Start the Windows Network Troubleshooter process
As part of the list of system check and fix processes, Windows Network Troubleshooter is a process that helps check and fix network connection errors on Windows. You can use it to consider your problem by right-clicking the network connection icon in the system tray and selecting Troubleshoot Problems.
The Windows Network Troubleshooter window will start and perform a check, resolving the network connection problem for you. If Troubleshoot detects a problem and successfully fixes it, Windows will automatically reconnect immediately afterwards. However, if you receive an error message with a specific name but Windows cannot fix it automatically, save it and study how to fix it on technology or forum pages.
4. Check valid IP address
At this point, we can verify that the problem is not temporary and that they are related to the hardware. Because Windows cannot fix this problem for you, we need to identify the cause ourselves.
And one of the most common causes of network connectivity problems is that the IP address has not been correctly assigned. Therefore, it is best to make sure your computer is being assigned a valid IP from the modem or router.
Specifically, to test this, right-click the network icon in the system tray and select the “Network and Sharing Center” command.
The Settings window appears, click on the Network and Sharing Center option on the right.
The network connection management window in Control Panel appears, click the name of the wired or Wi-Fi network connection.
In the status window of the selected connection, click the Properties button in the Activity section and then double-click Internet Protocol Version 4 (TCP / IP v4). Make sure “Obtain an IP address automatically” and “Obtain DNS server address automatically” options are highlighted. Then, the system will automatically be assigned the IP from the modem or router correctly. You can repeat the same steps with the IPv6 address in Internet Protocol Version 6 (TCP / IP v6).
Once you have done the above steps, you can check further to make sure that the computer being assigned by the router has a valid IP address. Open the Windows PowerShell command-line interface by right-clicking the Start button and selecting Windows PowerShell (Admin). Next, type “ipconfig” command and find the information below the Ethernet adapter section (for wired connection) or Wireless LAN Adapter (for wireless connection).
Next, enter the “ipconfig / release” and “ipconfig / renew” commands one after another in order for the router’s computer to issue a new valid IP address.
5. Try running Ping and Trace commands
If the IP address has been re-issued but the problem has not been resolved, the main reason may be the router with the Internet.
We continue to solve it by trying to type “ping 188.8.131.52” to Google’s DNS servers to check if the computer can connect to the Internet. The above action will send 4 packets to Google.
If that fails, you will receive a message saying which packet has encountered a problem while sending. For more information, type “tracert 184.108.40.206” to track the path of each packet between your computer and Google’s DNS servers.
When running the above commands, you can see if the packets were sent successfully. If unsuccessful, you can check to see where the problem is happening, on the local network or outside the Internet.
6. Contact the operator
If you have done all the above steps basically like checking the device is working properly, the computer is assigned a valid IP address from the router and eventually detects the problem is happening outside the network. Internet, … that your computer still can’t access the Internet, the next best solution you should do is contact your network provider to report the problem.
7. Finally … wait!
After letting the network know about the problem, all you can do is wait. In most cases, you cannot fix network-related network problems yourself, but wait for the vendor’s technical staff. Or even in cases where international transmission is interrupted for some reason, you may have to wait longer before being connected again.
