The laptop can t find WIFI, and it has been restarted several times. What to do???

Check whether the wireless card switch is turned on, and then see if the driver is normal. Then reconnect again.

Check whether the wireless network card is turned on, most notebook wireless network card switches are fn+f5, and the driver of the wireless network card is good?

This is either your network card is not good or it may be that the network is unstable, it is best to wait a minute, there may be a network failure.

Because the option to "Allow the computer to turn off this device to save power" is set, you can turn off this feature. Here's how:

1. First of all, right-click on the start menu and select the "Device Manager" option as shown in the image below.

2. Secondly, select the "Network Adapter" option in the list as shown in the image below.

3. Next, select the NIC, then right-click and select the "Properties" option in the list as shown in the image below.

4. Then, select the "Power Management" tab and uncheck the option "Allow the computer to turn off this device to save power" as shown in the image below.

5. Finally, click the "OK" button in the lower right corner of the window, as shown in the figure below. In this way, the above problem is solved.

Answer: This situation is generally due to the installation of some domestic optimization software for "optimization" or "junk cleaning", resulting in the disabling or loss of the driver of the network card. You only need to uninstall the optimization software and reinstall the driver of the network card once to solve the problem. If it is a wireless network card, and it still can't be solved after pressing the above operation, you can try the following methods:

1. Device Manager, right-click the wireless network card - Properties, put, the default is 20mhz, change it to 20 40 Open the network and sharing center - upper left corner - manage wireless network, after the relevant icon pops up, right-click the previous wireless network - delete the network. 3. After deleting, reconnect to the wireless router, enter the user name and password, and then pop up the window, be sure to select the public network. If it still doesn't work, you can try to connect the router with wires first, then log in to the router's management page, find the wireless network settings page, change the band bandwidth to 20MHz, and then save and exit, which can generally be solved.

1 Address conflicts, which are especially common when using W7 systems. It's useless to change ipdns. Because the problem is that the pace of notebook refresh is slower than that of desktops and mobile phones, causing others to change him and not keep up.

Squeeze it out. It may even be disconnected due to conflicts, along with other devices. Most likely, it used a computer with the conscience of the American imperialists, and the network card was too weak.

If you don't want to be annoyed by changing places, upgrading W10 will reduce the probability. In fact, there is a 100% solution to the problem that can be solved by giving the conscience of the US imperialists to connect to the wired network, and other devices continue to use wireless.

2 Or because of the use of the computer with the conscience of the United States, their motherboard is a custom cut corners bargain, the power supply is problematic and prone to electromagnetic interference. When a slight noise is randomly emitted that is imperceptible, the line will be disconnected, and you can hear it if you listen carefully. Just select Disable and then turn it on.

Right-click on the computer, find Device Manager, go in and find the network adapter, click the small triangle next to it, then right-click on that what what adapter, click Disable, and then click Enable after a while, if not, click Uninstall, the pop-up window does not need to check any options, click OK directly, and then right-click on the network adapter, click Scan to detect hardware changes, you can, but it still can't solve the fundamental problem!

The same problem has not yet been completely solved. In the past, I used to restart directly, but later I found that I could reconnect by starting sleep mode and waking up. At least it doesn't have to be rebooted.

I've been bothered by this problem for a long time, the wifi of the mobile phone is nothing at all, that is, the computer wifi is interrupted once an hour on time, as if a timer is set, and it takes more than a minute to reconnect.

Mine is just press fn and f3 at the same time (long press).

I also have this problem.,Wake up after sleep.,Win10 system.。

I'm also having this issue and it's not being resolved now.

Mine is also in this situation, and it has not been solved until now, and I have not seen a reliable answer.

2.Check whether the laptop has a wireless switch, some old laptops will have a separate wireless switch button on the trackpad or some other positions on the fuselage or can be turned on and off wirelessly by a combination of keys between FN+F1-F12, so the first step is to check whether there is this switch, if so, you need to turn it on.
