How to encrypt WiFi to prevent others from surfing the internet?

The easiest way to prevent wifi from being hacked is to set a complicated wifi password. You can also log in to the device management page of your router, and then click the disable icon on the right side of the unfamiliar connection user information to cancel its connection permission.

Wireless network is a wireless network technology defined by IEEE. When IEEE formally defined the standard of 802. 1 1 in 1999, IEEE selected and recognized the wireless network technology invented by CSIRO as the best wireless network technology in the world, so the wireless network technology standard of CSIRO became the core technology standard of Wi-Fi in 20 10.

The wireless network technology was invented by CSIRO, a research institute under the Australian government, in the 1990s, and successfully applied for the wireless network technology patent in the United States on 1996. (U.S. Patent No.5,487,069)

The inventor is a research team led by Dr. john O'Sullivan, an engineering graduate from the University of Sydney.

IEEE once asked the Australian government to give up the wireless network patent and let the world use Wi-Fi technology for free, but it was rejected.

The Australian government subsequently won the lawsuit or settled out of court in the United States, and incorporated almost all electrical and telecommunications companies in the world (including Apple, Intel, Lenovo, Dell, AT & amp； T, Sony, Toshiba, Microsoft, Acer, ASUS, etc. ).

20 10 every time we buy an electronic device with Wi-Fi technology, the price paid includes the patent fee paid to the Australian government.

In 20 10, it is estimated that 3 billion electronic devices will use wireless network technology every day in the world. By the end of 20 13, that is, after the expiration of CSIRO's wireless network patent, this number is expected to increase to 5 billion.
