If I am abroad, I can make phone calls, receive text messages and surf the Internet, but I can't send text messages. Where is this?

There are many reasons why computers can't get online, and the solution can only be to eliminate them, that is, to test them one by one to see if they are caused by this reason. If this is the reason, then it is possible to solve the problem, so the first thing to do is to find out the reason why the computer can't access the Internet.

Whether it is overdue, take the last bill to see if it is overdue. If it expires, it can be renewed.

What we can't solve is whether the communication company has problems and needs to call for advice. If so, we can only wait for them to solve the problem.

It is also very common that computer poisoning leads to the inability to access the Internet. Of course, it's better to solve it. If it is caused by a virus, it can be solved after antivirus.

Network firewall problems, if the network firewall is not set properly, such as the security level is too high, IE is accidentally put into the blocked access list, and the firewall policy is wrong. You can try to check the policy, lower the security level of the firewall or close it directly to see if it is back to normal.

Internet protocol and network card driver problems, IE can't browse, which may be caused by network protocol (especially TCP/IP protocol) or network card driver damage. You can try renaming the network card driver and network protocol.

Problems with the HOSTS file, modifying the HOSTS file will also lead to abnormal browsing. The solution, of course, is to empty the contents of the HOSTS file. You may not know the location of host, but this is C:WINDOWSsystem32driversetc.

Of course, the computer's inability to access the Internet is by no means limited to the above items. The above are the common reasons and solutions for not being able to surf the Internet, and there are many or many inexplicable reasons that can only be solved one by one. There is no other way, but in the case that the cause of the problem cannot be found for a long time, the final solution can be to reinstall the system. This may not be professional, but you will like this method. Now it takes only a short time to restore or reinstall the system, and it can be completed in a few minutes without manual intervention. After the system is restored, if it is not the problem of the communication company, the problem will be solved instantly. But in order to compete, it took a long time to solve this problem, and it will be a bit thankless to solve it all the time, so it depends on the individual. There are many solutions, the key depends on how to choose.
