Keep your WiFi wireless network secure.

1. See what security measures are available in your home WiFi network

When your friends first visit your home and use your WiFi network, do you need to enter a password? If not, your network is not secure enough. Even if they need to enter a password, there are several ways you can protect your network, and there are pros and cons to these methods. You can see what protection you have on your network by looking at the WiFi network settings. Your network may be unsafe, or you may have added protection such as Wired equivalent encryption (WEP), wireless network security access (WPA), or second-generation wireless network security access (WPA2). Where WEP is the oldest wireless security protocol, the effect is poor. WPA is superior to WEP, but WPA2 is the best choice.

2. Change your network security settings to WPA2

WiFi signals are generated by a wireless router in your home. If your network does not have WPA2 protection, you will need to access the Router Settings page to make changes. You can consult the router user's manual to learn how to access the Settings page, or to search online for guidance on your own router. All routers that have a Wi-Fi logo on sale after 2006 years will support WPA2. If you are buying an earlier model, we recommend that you replace the new router that supports WPA2. Because it's safer and faster.

3. Set a high strength password for your wifi network

To use WPA2 to protect your network, you need to create a password. It is important to choose a unique password, preferably using a long password consisting of numbers, letters, and symbols, which is not easily guessed by others. If you are at home in such a private place, you can also record the password so as not to forget, and safe custody, so as not to be lost. In addition, your password needs to be easy to use so that your friends can connect to your home WiFi network when visiting. Just as you don't give your own keys to strangers, the WiFi code in your home can only tell people you trust.

4. Protect your router to prevent others from changing your settings

Your router needs to set up a separate password that distinguishes it from the password that protects the WiFi network. New routers generally do not set a password, or only a simple default password, many network criminals have already known this password. If you do not reset your router password, criminals anywhere in the world can easily invade your network, intercept data that you share over the network, and launch attacks on computers connected to the network. Many routers can reset the password on the Settings page. This set of passwords should not be told to others and needs to be distinguished from the WiFi password (as described in step three). If you set the same password for both, anyone with your home WiFi password will be able to change the settings of your wireless router.

5. If you need help, please consult the instructions for use

If you lose the router manual, you can also find the model of the base station or router used in your home in the search engine, and the information on many devices can be found online. If this is not the case, you can also ask the router manufacturer or network service provider for help.
