Know how to rub the network card
"Rub network card" is a WiFi Wireless LAN network card, compared with the standard wireless network card, mainly has the following characteristics:
1. High transmitting power
China does not appoint the antenna gain less than 10dBi of 2.4GHz Wireless LAN products equivalent total radiation power (EIRP) must be less than or equal to 100mW, the EU CE Certification standard also stipulates 2.4GHz Wireless LAN products equivalent total radiated power (EIRP) to be less than or equal to 100mW, So the standard wireless router and wireless network card transmitter power is generally between 50-100mw, and "Rub network card" transmission power is generally above 800mW, is the standard wireless product more than 10 times times, and mobile phone is quite, the radiation is strong, is a serious exceeding the standard products, long time, close range of use will affect human health.
2, can crack the password
This type of network card is generally equipped with BT3/BT4, such as cracking software, but can only crack WEP encryption, the use of WPA-PSK/WPA2-PSK AES encrypted wireless router is powerless, so as long as the appropriate encryption method, can completely prevent malicious rub net.

Understand the "RUB network card" characteristics, anti-RUB network is relatively easy. Tp-link all wireless routers support the WPA-PSK/WPA2-PSK security mechanism, as long as the user chooses the WPA-PSK/WPA2-PSK security type when setting up the router, and specifies the encryption method for AES encryption, can effectively protect the wireless network security, To prevent the misuse of the network family.

For the Tp-link 11N wireless router and wireless USB network card, 150M wireless router and wireless USB card, users can also quickly set up AES encrypted wireless network by QSS The Fast security setting feature. If the user is supporting the use of the above products, just in two minutes, respectively, click on the router and the QSS button on the network card, you can easily in the wireless network card and wireless router to establish a WPA2 level of AES encryption security connection, no memory password, you can effectively prevent "rub network card" embezzlement.
Tp-link all wireless products have supported the WPA/WPA2,WPA-PSK/WPA2-PSK encryption mechanism, and the hardware to implement the AES encryption algorithm, encryption and decryption process more efficient, so that users in the use of AES encryption to ensure wireless network security, while wireless performance is not affected, Make sure users surf the internet as smoothly as they do. In addition, Tp-link products also support wireless MAC address filtering, SSID hiding, firewall and other functions, users can further protect their wireless network.
