Your router helps distribute the Internet throughout the network, but there is also a risk that the device will not only own the Internet. Hackers have become smart enough to spread malware, ransomware and other network security threats, putting the entire network at risk.

How to protect your WiFi and router

It is reported that hackers have been using covid-19 applications concerned by users in vulnerable exposed routers, and then maliciously nested them. The question now is, how to protect routers from such threats?

Although this seems to be an insurmountable task, there are some things you can do to protect routers and WiFi from hackers.

1: Adjust router settings

The first step you should take is to check the security settings of your router. Many users leave the default settings in place, but do not realize that they can be adjusted. Their adjustment level depends on the router itself, but all routers have certain defense capabilities.

Log in to the router settings. Login information shall be provided with the router, usually including IP address and password. Here, you should change your login information regularly to avoid too single password, so changing your password regularly will make it easy for hackers to log in to your network.

2: Change the name of WiFi

Next, you should change the WiFi name. The service set identifier (SSID) is the default name for the network. Leaving it as is will make it easier for outsiders to simply scan the network name to find it. First, if you change the name, it will be difficult to find your network.

3: Disable network name broadcasting

This should be in the router settings. Networks that share their WiFi (such as coffee shops, libraries or hotels) use this feature. This feature is not required for your private home network. Turning it off removes your network from the list of open networks.

4: Turn on network encryption

Many routers have built-in encryption settings, which sometimes turn off. See if you can turn the router on when you first set it up. The available encryption should be WPA2.

5: Check if the router has a guest network

We are not suggesting that it may not be safe for friends to use your password, but if you can let them access the guest network through the router (rather than the actual network), you can improve the overall security of the network.

In any case, you really shouldn’t provide the network password at will, so you can choose to build a public network for visitors to use alone, which is also a method.

6: Check the firewall of the router

All tri band routers or dual band routers will have built-in firewalls of some types. This does not mean that the firewall will open automatically. A software firewall can protect your network from intrusion. If your router does not have a firewall, you should consider buying a new router or buying a separate firewall device to make the network as secure as possible.

7: Use VPN

A VPN, or virtual private network, is a bridge to encrypt your communication and let your network communicate with the outside world. It can ensure that after the data packet reaches the destination VPN device, it will be unsealed, and the data packet will be decrypted after checking the digital signature.

8: Keep software and firmware up to date

Manufacturers will update the software and firmware of their devices from time to time and update any information about new malware or viruses. Now, when you update the system, it will be able to find and exclude new threats. If security updates are available, do not delay downloading them.

9: Off line shutdown

If you are going to be offline at any time, it is best to turn off the router so that people with ulterior motives can leave the network. If you have many people in your family, this may not work properly.

10: Buy a new router

Finally, how old is your router? Older routers will not have all the security features that come with the new router. Moreover, there are more choices today than in previous years. Updating the router can not only make your network more secure, but also speed up.

If you are sensitive to the privacy of the network, clear your sensitive personal information in time, change your password in time, and keep all contents up-to-date, you should be able to ensure the security of the router.
