How on the laptop to turn off the Wi-Fi? How to change the password for wi-fi

The desire to turn off Wi-Fi on the laptop can arise for various reasons. For example, you are on the road. There is no Internet, and the transmitter simply spends charging the laptop to find non-existent networks. Or you have a wired Internet connected to your laptop, and you do not need this wy-fay for free. In any case, you need to know how to turn off the Wi-Fi on the laptop. The same story and with a password change. If you notice that there is a "vampire" attached to your network, the best option is to learn how to change the password for wy-fay, and do it. So this little "illiteracy" will be useful for everyone.

What can affect the turn off wi-fi?

This is a legitimate question, because everyone wants to know about the possible risks, consequences and bonuses. In principle, if the Wi-Fi network is disabled on your laptop, nothing terrible will happen. Well, the internet will be gone. That's all. In return, you will get an excellent bonus: your laptop will be able to work much longer on battery power. In some cases this is crucial. And the Internet is not so important. You can live without it.

The same story and with a password change. But here everything is a bit more complicated. Your laptop will not automatically connect to the access point because the password has been changed. I'll have to reconfigure the connection. That's all. But, if you come up with a "zubodrobitelny" password, then no intruder will be able to more impudently connect to your wi-fi and shamelessly take advantage of the free Internet.

Lenovo. Disconnecting Wi-Fi

How to disable Wi-Fi on Lenovo laptop? You can do this in several ways. The first is using the laptop's hot keys. For most models, the Fn + F5 key combination is enough to turn off Wi-Fi. This will immediately turn off the transmitter. You can enable the reverse network with the same combination. Everything turns on and off very quickly.

But there is in some models (especially old ones) a switch located on the body of the device. It can be anywhere: from the side, from the front, from behind. But he is. To turn off the transmitter, just move the switch to the "Off" position and the network will immediately turn off. This is a hardware way to disable wi-fi. And the first was software, which works only if the laptop has the necessary system drivers installed.

ASUS Notebooks

In the case of the Korean manufacturer, everything looks different. Many models are equipped with hot keys to disable the Wi-Fi transmitter, but each model can have its own combination. There is no particular constancy here. How to disable Wi-Fi on the laptop "Asus"? To do this, hold down the key combination Fn + F2. If this helps, then we will not have to resort to searching for other methods.

If this combination does not work, you will have to carefully study the icons pictured on the function buttons. Look for something that looks like a transmitter with a signal. If you find it - boldly press. If your laptop is so old that the icons are erased, then you should try random combinations. At least one will work. All that you accidentally turn off, you can easily turn on again. Let's proceed to the next step in the instruction "How to turn off Wi-Fi on the laptop".

We use system capabilities

If the hot keys of laptops for some reason do not work, then you can use an alternative option - system options. How can I turn off Wi-Fi on my laptop with the help of the operating system? Very simple. In Windows, the tenth and eighth versions, it is enough to click the left mouse button on the wy-fay image in the system tray. Immediately, the side menu pops up, in which it is enough to move the slider to the "Off" position. The transmitter will immediately turn off.

With the seven, everything is a bit more complicated. There's no option to turn off wi-fi right from the interface. To disable it, you need to right-click on the Wi-Fi icon, go to the "Network and Sharing Center" menu item, then go to the "Change adapter settings" tab. Here we select our wireless connection, right-click and select "Disconnect". A bit more complicated than in the eight and ten. But the result is the same.

Replace the password for wi-fi

Change the password from the wi-fi is done in the settings of the router (router). The sequence of actions depends on the particular model and manufacturer. But in general, the replacement algorithm is similar. Therefore, consider the example of changing the password on the router from "Asus".

First you need to enter the router's menu. To do this, enter the address line in the browser http://192.168.1.1. We will be politely asked to enter your login and password. In both fields, enter the word admin. Now we are in the router menu. We search for the item "Settings", then "Wireless network" and "General". The password from the wi-fi is hidden under the asterisks in the "WPA Preliminary Key" field. It is in this field that we need to enter a new password. After entering, we press the "Apply" button. All. Password changed successfully. Now the free wi-fi of the laptop will not get to others.

General recommendations for choosing a password

Before you learn how to change the wy-fay password, you need to understand some of the features of creating a new password in order for your wi-fi network to be difficult to break. By default, modern networks with security use an eight-digit password. But eight characters is the minimum. In fact, the password can be any number of characters. And the more, the better.

To create a password, it's best to use a combination of random numbers, uppercase and regular English letters. Moreover, the more random the combination, the better. The more you can hope that the password will stand even against the most sophisticated methods of hacking. Everything else relates to the purely technical side of the question. To create a random password, it is better to use online generators. Do not use names, dates or common names. For the best result, use this method: take eight random words and from each select one random letter. This will not allow attackers to easily break the protection.

What certificate to use?

A security certificate protects the connection. The more perfect it is, the safer. To date, there are types of certificates WEP, WPA-PSK and WPA-PSK2. The first two are hopelessly out of date. And in their best years they were quite leaky. But the last one to date is the most protected. It should be used. Because the connection must be reliably protected from penetration from the outside.

The main thing is to remember that no matter how secure the certificate is, it turns into nothing with a weak password. If you have a password - four units, then no super secure security certificate will help you. Any monkey with a keyboard will be able to hack your wi-fi. The laptop will also be under attack if you have enabled file and folder sharing.

Which one to choose the type of encryption?

Here everything is simple. Each certificate has its own type of encryption. If you change it arbitrarily, then wi-fi just will not connect. Already obsolete and insecure type TKIP was used together with WEP-certificate. It goes without saying that now its use will be impossible. But WPA-PSK2 uses the AES encryption type , which is much more reliable than its ancestor. If you try to forcely change the type of encryption, then you simply will not have a connection. So do not experiment.

The type of encryption affects many factors. But the most important of them is security. The more sophisticated the encryption, the more difficult it is to crack the connection. But remember, there are absolutely no reliable methods of protection. Even the most perfect type of encryption can be cracked for once or twice by some self-taught hacker. So the best way to achieve maximum security is to change your password at least once a month.

Conclusion

Thanks to this small "illiteracy" you learned how to turn off the Wi-Fi on the laptop and change the password on the router. Information on security certificates and encryption types was also very useful. Now you can easily do everything necessary. The main thing is to follow this instruction clearly and not to engage in amateur activities. Otherwise, you can twist such cases, that no expert then can not fix it.
