Wireless fidelity (wifi) adalah teknologi yang memungkinkan pengguna dapat mengakses internet dari berbagai perangkat. Wifi, yang kini dengan mudah dapat ditemui, adalah nama paten dari lembaga pengembangan teknologi Wifi Alliance, yang bertujuan memperbaiki produk Wireless LAN berbasis standar IEEE
Lantaran sifatnya yang nirkabel, memang menjadi nilai tambah yang patut dipertimbangkan. Akan tetapi, para pengguna juga sebaiknya berhati-hati terhadap “ancaman virtual” yang dikhawatirkan dapat menembus jaringan wifi.
Khusus pengguna rumahan, setidaknya ada tiga langkah yang dapat dilakukan untuk menjaga jaringan wifi.
Pertama adalah meletakkan antenna router wifi di bagian tengah bangunan atau ruangan, agar sinyal wifi tidak sampai keluar rumah maupun ruangan.
Langkah berikutnya adalah dengan menggunakan wireless encryption protocol (WEP). Enkripsi adalah proses mengacak data sehingga hanya dapat dibaca oleh pihak-pihak tertentu. Pengguna harus menyertakan kunci untuk membuka data yang dienkripsi.
Langkah terakhir adalah dengan menyetel router agar mampu melakukan identifikasi dan membuka koneksi internet hanya kepada perangkat yang berhak mengakses
Wireless fidelity (wifi) is a technology that allows users to access the internet from various devices, like cell phones and notebook wirelessly. Wifi, which now can easily be found and felt in a cafe, restaurant or other public place, is the name of the patent of the technology development institutions Wifi Alliance, which aims to improve wireless LAN products based on IEEE standards
Ease and practicality wifi, because its wireless, it is an added value to consider. However, users should exercise caution against "the threat of a virtual" who feared could penetrate the wifi network.
Therefore, a special home users, at least there are three steps that can be done to keep the wifi network.
First is the extent possible to put the wifi router antenna in the middle of the building or room. This meant that the wifi signal not to leave the house or room that it is feared even a crack parties who are not responsible.
For the record, in a simple router is the "bridge" that connects two or more networks and serves to look at the various destination addresses of data packets through it and choose where the packet should be sent.
The next step is to use wireless encryption protocol (WEP) whose function is to conduct encrypted communication on a wireless network wifi. Encryption is the process of scrambling data so it can only be read by certain parties. In some of the encryption process, the user must include a key to unlock the encrypted data.
The final step is to set the router to be able to identify and open up the internet connection only has access to the device, which it called a Service Set Identifier (SSID). Thus, it can be protected wifi network and your own can be more comfortable when surfing in cyberspace.
