Problem description: My laptop has been using the network on the wireless router before, the network speed and stability are very good, but because of a period of busy work, there has been no Internet access for a while, today I opened the computer and found that the wireless route search can not be signaled, the lower right corner of the display of a kind of red cross that we commonly see, the link signal displayed by the wireless network is also less, the wireless signal light display is not normal, the search for a long time did not find anything wrong, I tried to restore the system and had no effect, I really don't know, I hope that the heroes of Qi9.com can give the little brother a clear path.

Maybe you want to know: how to understand the computer's virtual memory odd 9 network: the computer has not moved, and the phenomenon of not being able to access the Internet normally is indeed rare, first of all, we need to try to check whether there is a problem with the driver of the wireless network card, if there is no driver wizard on the computer, the computer can not be used for wired network**, you can go to the computer store to buy a disc, and then install it on the computer, check that there is no problem with the computer driver, or reinstall the driver of the wireless network card.

If the problem has not been solved, you can try to use the program to reinstall the connection of the wireless router to search for the signal, and see if there is a problem with the software, if it is a problem with the software, then I think it can solve the problem if you reinstall the software to teach.

What should I do if my computer can't connect to the Wi-Fi?

First of all, look at the lower right corner of the computer to see if there is a wireless network icon, if not, it is the computer's wireless network card driver is broken, you can reinstall it.

If the network card driver cannot be installed, it may be a conflict between the system and the driver, and you can consider redoing the computer system to solve the problem.

If there is a wireless network card driver, but it is not connected to the Internet, you need to see whether your external network is unblocked, if not, it needs to be repaired by the operator.

Check whether the wireless card driver is installed correctly (find the corresponding wireless card in the device manager and see if there is an exclamation mark or abnormal condition) or right-click on the wireless network to diagnose it.

You can use PC Manager to fix it and see if it can be solved.
