"Channel NICs" are Wifi wireless LAN cards. Compared with standard wireless NICs, they have the following features:
The equivalent omnidirectional radiated power (EIRP) of the 2.4 GHz wireless local area network antenna with a gain less than 10 dBi in China must be less than or equal to 100 mW. The EU CE certification standard is also equivalent to 2.4 GHz wireless LAN products. Omnidirectional radiated power (EIRP) is less than or equal to 100mW, so the standard wireless router and wireless network card transmit power is generally between 50-100mW, and the "蹭 network card" transmit power is generally more than 800mW, is the standard wireless products More than 10 times, and mobile phones, radiation is strong, is a serious product, long time, close to use will affect human health.
2. It is possible to crack passwords.
This type of network card is generally equipped with cracking software such as BT3/BT4, but it can only crack WEP encryption, and it uses WPA-PSK/WPA2-PSKAES encryption. The wireless router is very effective, so just select the appropriate encryption method, you can completely prevent malicious network.
How to prevent flooding networks
Understanding the characteristics of "silver network cards", flood prevention networks are easier. All TP-LINK wireless routers support the WPA-PSK/WPA2-PSK security mechanism. As long as the user sets the router, select the WPA-PSK/WPA2-PSK security type and specify the encryption method as AES encryption. The safety of preventing cricket nets.
Router Settings For TP-LINK 11N wireless routers and wireless USB network cards, 150M wireless routers, and wireless USB network cards, users can also quickly set up AES-encrypted wireless networks using the QSS Fast Security feature. If the user is using the above products, simply press the QSS button on the router and the network card within two minutes, you can easily establish a WPA2 level AES encryption secure connection between the wireless network card and the wireless router, without the need to memorize the password. You can effectively prevent "cards" card.
TP-LINK All wireless products have support WPA/WPA2, WPA-PSK/WPA2-PSK encryption mechanism, and use hardware to implement AES encryption algorithm, encryption and decryption process is more efficient, so that users use AES encryption to ensure wireless network security while wireless performance Unaffected, ensuring that users surf the Internet as smoothly. In addition, TP-LINK products also support wireless MAC address filtering, SSID hiding, firewall and other functions, users can further their own wireless network through these functions.
