The reasons why the computer cannot connect to WIFI after hibernation are as follows: If you use a simple router that plugs into the USB interface of the computer, the computer will not sleep, and the network card will be in a sleep state. The network card will no longer lend the network to the simple router, so there will be no wifi signal.The solution is to change an external router, which can not only connect to the computer, but also send wifi signals.For example, the newifi produced by Baidu and Lenovo.
Wi Fi is a technology that can connect terminals such as personal computers and handheld devices (such as pads and mobile phones) to each other in a wireless way. In fact, it is a high-frequency radio signal.Wi Fi is a brand of wireless network communication technology, which is held by the Wi Fi Alliance.The purpose is to improve the interoperability between wireless network products based on IEEE 802.11 standard.
Move the mouse to "Computer", click the right mouse button and click "Management". There is a "Device Manager". Double click the device manager and find the "Network Adapter" in the middle. Double click the wireless network card and the wired network card (usually all in English). The following interface will pop up

Basic judgment: It's impossible. You don't understand the status of the machine. It's almost the same as power-off. The difference is that it transfers memory resources to the hard disk for storage, and then transfers them to the memory for operation after the machine is fully powered on, as before hibernation; Reason description: The hotspot can only be used when it is in the running state when it is turned on. This is a common sense problem. If your system is not running, how does the virtual wireless routing tool you have established work.Give up this groundless idea.Only in the power on state.I wish you a happy Internet experience.eighty-eight To add, some netizens said that, regardless of the logout method, this can only keep the local network open, but if the virtual routing tool cannot run, it cannot transmit wireless WIFI signals.
