Method One, wireless card driver problem
1. If I go to the official to download the wireless network card driver
2. Now go to the official page we search the model of our own computer, as shown in the picture.
3. We clicked on the wireless network card driver and then click the download driver.
4. Download the computer we have wireless network card driver installation and restart the computer problem solved.
Method Two, other reasons (fixed IP)
1. If the above method is invalid, we can try to give the computer a fixed IP,
2. In the computer "start"-"Control Panel"-"Network and Sharing Center" click to enter, as shown in the picture.
3. Then we will see a "WLAN" click on the right to enter.
4. Then in the pop-up window we clicked "Properties" as shown in the picture.
5. Now generally used IPv4, we click on IPv4, and then click "Properties" as shown in the following figure.
6. Now we are entering a static IP address, usually before the 192.168.1.2-192.168.1.255
7. Finally switch the WLAN switch, reconnect, see already normal
Ok, method Two is I see from another friend, hope can solve your problem.
