How to encrypt a wireless router

1. Enable WEP encryption on the wireless router

First, let's cite an example to illustrate implementing 128-bit WEP encryption. Now let's look at how to use this WEP key to set up a wireless router.

Wireless router Encryption It is important to note that when you configure this part, you should also use wired to connect to the wireless router, because if you lose your wireless key, you will not be able to connect to the wireless router with the correct key. As in the previous wireless router settings, use your Web browser to access the wireless router and click on the Wireless Parameters tab. Click Basic Settings, first turn on security settings, on a row labeled Security type, select WEP.

Select 16 in the key format, enter the key, and click Save. Write down this key. After you click Save Settings, any computers that were previously connected to the wireless router will lose connectivity. This is normal because you have modified the way they communicate with the wireless router, but you have not yet told them what security key to use to access the wireless router.

　2. Enable WPA encryption on the wireless router

To make a comparison with enabling WEP encryption, let's look at how to enable WPA encryption, which is similar to enabling WPA encryption, but a bit different, before you can enable WPA encryption, you have to decide how long the encryption key is valid, for example, if you set it to 1800 seconds , for 30 minutes, the wireless router and wireless card will generate a new key after the key has been used for 30 minutes. If a hacker cracked the key within 30 minutes, the key would be worth less than 30 minutes, because it would have become another new key after 30 minutes, and the hacker would have to start cracking it again. The following is an example of setting up WPA on a wireless router.

In the wireless parameters, select Enable security settings, select Wpa-psk, select the security option WPA-PSK, select the encryption method, enter the PSK password. In the place marked with the WPA shared key, enter the preshared key and, where the group key is updated, enter how long the key will be updated. We select 1800 seconds in this example and click Save Settings.

Wireless router encryption needs to note: How long should we set the key update time? There is no good answer, if you set it too short, such as 1-2 minutes, it is true that security is improved, but for some network cards, this may cause some connection problems. We recommend it according to the manufacturer's default value. For WPA encryption to be enabled, we also need to tell each wireless card the super password so that they know how to decode the call to the wireless router. Set up each machine in the wireless home network in turn, and remember to check to see if you have connected to the wireless router every time.

Tips for troubleshooting: Wireless router Encryption

If some computers are unable to re-establish the session, the following items need to be checked: Verify that the wireless router and wireless network card are encrypted in the same way. Verify that the passphrase used to generate the WEP key (or WPA key) is the same in the wireless router and the wireless card. This passphrase is case-sensitive, for example, "P" and "P" are not the same. So when you set the time to carefully input, pay attention to the difference between uppercase and lowercase letters. If not, then disable encryption in both the wireless router and the wireless network card, and verify that the connection can be established without enabling encryption.
