Here is the issue: Every time after I login into the account, about 20 minutes later, the wifi will be disconnected automatically. I even cannot reconnect the wifi manually, the only thing that I can do is to reboot the laptop. After login again, wifi can be connected (but through manual way). By the way, during the period of wifi disconnection, I checked the "Wi-Fi Networks" by click "Select Network" in order to try to reconnect it manually. But I found that there is only one SSID which previously the laptop connected to. However, I was definitely sure that there should be more than one SSID being showed in the wifi list. Even for this only one SSID, like I mentioned before, I cannot reconnect manually unless I reboot the system. Finally, I set the wifi to be connected automatically after I login to the system, however, it just can't. I can only connect to the wifi manually after I login to the system.
